Reported by Daniel P. Berrange.
A lock manager may operate in various modes. The direct mode of
operation is to obtain locks based on the resources associated
with devices in the XML. The indirect mode is where the app
creating the domain provides explicit leases for each resource
that needs to be locked. This XML extension allows for listing
resources in the XML
<devices>
...
<lease>
<lockspace>somearea</lockspace>
<key>thequickbrownfoxjumpsoverthelazydog</key>
<target path='/some/lease/path' offset='23432'/>
</lease>
...
</devices>
The 'lockspace' is a unique identifier for the lockspace which
the lease is associated
The 'key' is a unique identifier for the resource associated
with the lease.
The 'target' is the file on disk where the leases are held.

I noticed this while building from libvirt.git on RHEL 5.6:
Generating internals/command.html.tmp
mkdir: cannot create directory `/internals': Permission denied
If I had been building as root instead, this pollutes /.
Older autoconf lacks $(builddir), but it is rigorously equal to '.'
in newer autoconf, so we could use '$(MKDIR_P) internals' instead.
However, since internals/command.html is part of the tarball, we
_already_ build it in $(srcdir), not $(builddir) during VPATH
builds, so the mkdir is wasted effort!
* docs/Makefile.am (internals/%.html.tmp): Drop unused mkdir.

Migration just seems to go from bad to worse. We already had to
introduce a second migration protocol when adding the QEMU driver,
since the one from Xen was insufficiently flexible to cope with
passing the data the QEMU driver required.
It turns out that this protocol still has some flaws that we
need to address. The current sequence is
* Src: DumpXML
- Generate XML to pass to dst
* Dst: Prepare
- Get ready to accept incoming VM
- Generate optional cookie to pass to src
* Src: Perform
- Start migration and wait for send completion
- Kill off VM if successful, resume if failed
* Dst: Finish
- Wait for recv completion and check status
- Kill off VM if unsuccessful
The problems with this are:
- Since the first step is a generic 'DumpXML' call, we can't
add in other migration specific data. eg, we can't include
any VM lease data from lock manager plugins
- Since the first step is a generic 'DumpXML' call, we can't
emit any 'migration begin' event on the source, or have
any hook that runs right at the start of the process
- Since there is no final step on the source, if the Finish
method fails to receive all migration data & has to kill
the VM, then there's no way to resume the original VM
on the source
This patch attempts to introduce a version 3 that uses the
improved 5 step sequence
* Src: Begin
- Generate XML to pass to dst
- Generate optional cookie to pass to dst
* Dst: Prepare
- Get ready to accept incoming VM
- Generate optional cookie to pass to src
* Src: Perform
- Start migration and wait for send completion
- Generate optional cookie to pass to dst
* Dst: Finish
- Wait for recv completion and check status
- Kill off VM if failed, resume if success
- Generate optional cookie to pass to src
* Src: Confirm
- Kill off VM if success, resume if failed
The API is designed to allow both input and output cookies
in all methods where applicable. This lets us pass around
arbitrary extra driver specific data between src & dst during
migration. Combined with the extra 'Begin' method this lets
us pass lease information from source to dst at the start of
migration
Moving the killing of the source VM out of Perform and
into Confirm, means we can now recover if the dst host
can't successfully Finish receiving migration data.

It was just pointed out that, although I added documentation for the
IPv6 additions to the network XML, I neglected to use those additions
in the examples. This patch adds an IPv6 address to each of the
examples except for the "default" network, since that is a faithful
reproduction of the default network config that's automatically
installed, which doesn't include any IPv6 address (for good reason -
because there is no such thing as IPv6 NAT, there is no one IPv6
address that would work for all installations).
Commit 78ba748ef1 claims to fix

documentation in formatdomain.html and libvirt.h. This patch completes
the task by fixing "virsh help memtune" output and memtune section of
virsh man page.
The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.
Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.
The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.
Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.

Some things to note in this patch:
- we do extend libvirt scope beyond purely managing domains, there is
already a number of blocks which are here as helpr functions to
manage the resources on the host.
- we are expanding in the direction of libvirt being sufficient to do
most of the management on the Host (but within the limits of the need
for virtualization, e.g. managing users on the host is out of scope)
- we don't require anymore APIs to be supported by multiple
hypervisors to get in, it's already the case in practice, but we
should still make sure the semantic of those APIs are clear. We
added quite a bit for QEmu, but for example I saw on IRC that VBox
could emulate a network unplug/replug on a domain interface, and
that would be a good addition even if a priori no other hypervisor
supports it.
- Make clear that all libvirt APIs are available remotely, which is
key to use libvirt for building management tools.
- link the goal page from the project main page
As for libvirt project directions, I think it just reflects the natural
evolution in the last couple of years. We are less hypervisor agnostic
and extending in the Host management. Clearly there is interest in
making sure libvirt is complete in term of features for the hypervisors
supported, especially the ones like KVM or LXC which don't really have
integrated management library.

The current LXC I/O controller looks for HUP to detect
when a guest has quit. This isn't reliable as during
initial bootup it is possible that 'init' will close
the console and let mingetty re-open it. The shutdown
of containers was also flakey because it only killed
the libvirt I/O controller and expected container
processes to gracefully follow.
Change the I/O controller such that when it see HUP
or an I/O error, it uses kill($PID, 0) to see if the
process has really quit.
Change the container shutdown sequence to use the
virCgroupKillPainfully function to ensure every
really goes away
This change makes the use of the 'cpu', 'devices'
and 'memory' cgroups controllers compulsory with

The Relax-NG schema for domains regarding <hostdev> doesn't match what's
implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The
implementation only requires @type, but the schema currently either
required none or all three attributes (@mode, @type, and @managed) to be
defined together, because they are declared in the same
<optional)-section. (@managed is currently even undocumented on
<http://libvirt.org/formatdomain.html#elementsUSB>).
Thus the following minimal <hostdev>-example fails to validate:
<domain type='test'>
<name>N</name>
<memory>4096</memory>
<bootloader>/bin/false</bootloader>
<os>
<type arch='x86_64' machine='xenpv'>linux</type>
</os>
<devices>
<hostdev type='pci'>
<source>
<address bus='0x06' slot='0x00' function='0x0'/>
</source>
</hostdev>
</devices>
</domain>
The schema is changed to match the current implementation:
1. @mode is optional (which defaults to 'subsystem')
2. @type is required
3. @managed is optional (which defaults to 'no')
The documentation is updated to mention @managed.

XSLT allows for two ways of generating the output of transformation.
Either implicit, which xsltproc prints to stdout and can be redirected
to a file using -o file. Or explicit, which means the stylesheet
contains <xsl:document> element which specifies where the output should
be saved. This can be used for generating more files by a single run of
xsltproc and -o directory/ can change the directory where the output
files will be stored.
devhelp.xsl is special in that it combines both options in one
stylesheet, which doesn't work well with -o:
xsltproc --nonet -o ./devhelp/ ./devhelp/devhelp.xsl ./libvirt-api.xml
Outputs 4 *.html files into ./devhelp but then tries to write to
./devhelp/ as a file (hence the I/O error) rather than writing output to
the fifth file devhelp/libvirt.devhelp.
This patch modifies devhelp.xsl so that all files are generated using
<xsl:document> element and -o directory/ can be used to override output
directory where those files are saved.
This patch adds the possibility to not just drop packets, but to also have them rejected where iptables at least sends an ICMP msg back to the originator. On ebtables this again maps into dropping packets since rejecting is not supported.
I am adding 'since 0.8.9' to the docs assuming this will be the next version of libvirt.

The problem was that, since a bridge always acquires the MAC address
of the connected interface with the numerically lowest MAC, as guests
are started and stopped, it was possible for the MAC address to change
over time, and this change in the network was being detected by
Windows 7 (it sees the MAC of the default route change), so on each
reboot it would bring up a dialog box asking about this "new network".
The solution is to create a dummy tap interface with a MAC guaranteed
to be lower than any guest interface's MAC, and attach that tap to the
bridge as soon as it's created. Since all guest MAC addresses start
with 0xFE, we can just generate a MAC with the standard "0x52, 0x54,
0" prefix, and it's guaranteed to always win (physical interfaces are
never connected to these bridges, so we don't need to worry about
competing numerically with them).
Note that the dummy tap is never set to IFF_UP state - that's not
necessary in order for the bridge to take its MAC, and not setting it
to UP eliminates the clutter of having an (eg) "virbr0-nic" displayed
in the output of the ifconfig command.
I chose to not auto-generate the MAC address in the network XML
parser, as there are likely to be consumers of that API that don't
need or want to have a MAC address associated with the
bridge.
Instead, in bridge_driver.c when the network is being defined, if
there is no MAC, one is generated. To account for virtual network
configs that already exist when upgrading from an older version of
libvirt, I've added a %post script to the specfile that searches for
all network definitions in both the config directory
(/etc/libvirt/qemu/networks) and the state directory
(/var/lib/libvirt/network) that are missing a mac address, generates a
random address, and adds it to the config (and a matching address to
the state file, if there is one).

Explanation
qemu's virtio-net-pci driver allows setting the algorithm used for tx
packets to either "bh" or "timer". This is done by adding ",tx=bh" or
",tx=timer" to the "-device virtio-net-pci" commandline option.
'bh' stands for 'bottom half'; when this is set, packet tx is all done
in an iothread in the bottom half of the driver. (In libvirt, this
option is called the more descriptive "iothread".)
'timer' means that tx work is done in qemu, and if there is more tx
data than can be sent at the present time, a timer is set before qemu
moves on to do other things; when the timer fires, another attempt is
made to send more data. (libvirt retains the name "timer" for this
option.)
The resulting difference, according to the qemu developer who added
the option is:
bh makes tx more asynchronous and reduces latency, but potentially
causes more processor bandwidth contention since the cpu doing the
tx isn't necessarily the cpu where the guest generated the
packets.
Solution
This patch provides a libvirt domain xml knob to change the option on
the qemu commandline, by adding a new attribute "txmode" to the
<driver> element that can be placed inside any <interface> element in
a domain definition. It's use would be something like this:
<interface ...>
...
<model type='virtio'/>
<driver txmode='iothread'/>
...
</interface>
I chose to put this setting as an attribute to <driver> rather than as
a sub-element to <tune> because it is specific to the virtio-net
driver, not something that is generally usable by all network drivers.
(note that this is the same placement as the "driver name=..."
attribute used to choose kernel vs. userland backend for the
virtio-net driver.)
Actually adding the tx=xxx option to the qemu commandline is only done
if the version of qemu being used advertises it in the output of
qemu -device virtio-net-pci,?
If a particular txmode is requested in the XML, and the option isn't
listed in that help output, an UNSUPPORTED_CONFIG error is logged, and
the domain fails to start.

In QEMU, the card itself is a PCI device, but it requires a codec
(either -device hda-output or -device hda-duplex) to actually output
sound. Specifying <sound model='ich6'/> gives us -device intel-hda
-device hda-duplex I think it's important that a simple <sound model='ich6'/>
sets up a useful codec, to have consistent behavior with all other sound cards.
This is basically Dan's proposal of
<sound model='ich6'>
<codec type='output' slot='0'/>
<codec type='duplex' slot='3'/>
</sound>
without the codec bits implemented.
The important thing is to keep a consistent API here, we don't want some
<sound> devs require tweaking codecs but not others. Steps I see to
accomplishing this:
- every <sound> device has a <codec type='default'/> (unless codecs are
manually specified)
- <codec type='none'/> is required to specify 'no codecs'
- new audio settings like mic=on|off could then be exposed in
<sound> or <codec> in a consistent manner for all sound models

QEMU supports serving VNC over a unix domain socket rather than traditional
TCP host/port. This is specified with:
<graphics type='vnc' socket='/foo/bar/baz'/>
This provides better security access control than VNC listening on
127.0.0.1, but will cause issues with tools that rely on the lax security
(virt-manager in fedora runs as regular user by default, and wouldn't be
able to access a socket owned by 'qemu' or 'root').
Also not currently supported by any clients, though I have patches for
virt-manager, and virt-viewer should be simple to update.

Currently, boot order can be specified per device class but there is no
way to specify exact disk/NIC device to boot from.
This patch adds <boot order='N'/> element which can be used inside

element. Since not all hypervisors support per-device boot
specification, new deviceboot flag is included in capabilities XML for

specification.

option will alleviate this problem (sndbuf=0 actually sets it to
0xffffffff).
Because we must be able to explicitly specify "0" as a value, the
standard practice of "0 means not specified" won't work here. Instead,
virDomainNetDef also has a sndbuf_specified, which defaults to 0, but
is set to 1 if some value was given.
The sndbuf value is put inside a <tune> element of each <interface> in
the domain. The intent is that further tunable settings will also be
placed inside this element.
<interface type='network'>
...
<tune>
<sndbuf>0</sndbuf>
...
</tune>
</interface>
This patch is in response to
https://bugzilla.redhat.com/show_bug.cgi?id=643050
The existing libvirt support for the vhost-net backend to the virtio
network driver happens automatically - if the vhost-net device is
available, it is always enabled, otherwise the standard userland
virtio backend is used.
This patch makes it possible to force whether or not vhost-net is used
with a bit of XML. Adding a <driver> element to the interface XML, eg:
<interface type="network">
<model type="virtio"/>
<driver name="vhost"/>
will force use of vhost-net (if it's not available, the domain will
fail to start). if driver name="qemu", vhost-net will not be used even
if it is available.
If there is no <driver name='xxx'/> in the config, libvirt will revert
to the pre-existing automatic behavior - use vhost-net if it's
available, and userland backend if vhost-net isn't available.
* docs/hacking.html.in (Curly braces): Tighten recommendations to
disallow if (cond) one-line; else { block; }.
* HACKING: Regenerate.
Suggested by Daniel P. Berrange.
At this point everything is already in place to make IPv6 happen, we just
need to add a few rules, remove some checks for IPv4-only, and document
the changes to the XML on the website.
This commit adds support for IPv6 parsing and formatting to the
virtual network XML parser, including moving around data definitions
to allow for multiple <ip> elements on a single network, but only
changes the consumers of this API to accommodate for the changes in
API/structure, not to add any actual IPv6 functionality. That will
come in a later patch - this patch attempts to maintain the same final
functionality in both drivers that use the network XML parser - vbox
and "bridge" (the Linux bridge-based driver used by the qemu
hypervisor driver).
* src/libvirt_private.syms: Add new private API functions.
* src/conf/network_conf.[ch]: Change C data structure and
parsing/formatting.
* src/network/bridge_driver.c: Update to use new parser/formatter.
* src/vbox/vbox_tmpl.c: update to use new parser/formatter
* docs/schemas/network.rng: changes to the schema -
* there can now be more than one <ip> element.
* ip address is now an ip-addr (ipv4 or ipv6) rather than ipv4-addr
* new optional "prefix" attribute that can be used in place of "netmask"
* new optional "family" attribute - "ipv4" or "ipv6"
(will default to ipv4)
* define data types for the above
* tests/networkxml2xml(in|out)/nat-network.xml: add multiple <ip> elements
(including IPv6) to a single network definition to verify they are being
correctly parsed and formatted.
In practice this has always been optional, but the RNG has shown it as
mandatory, and since all the examples for make check had it, it was
never noticed. One of the existing test cases has been changed to
check for this.
I also noticed that the dhcp/host/ip was still defined as <text/>,
but should really be <ref name='ipv4-addr'/>
formatnetwork.html has a menu item at level 3. libvirt.css
doesn't have a explicit rule for level 3 and level 3 and
level 2 items end up at the same indentation level.
Add an additional 1em indentation to level 3 menu items.
The xml watchdog dump option is converted to qemu watchdog pause arg
but it is not reasonable to convert it back from qemu watchdog pause
arg since there already is a xml watchdog pause option, so a test for
the dump option to convert it from arg to xml is not added.
Changes common to all network disks:
-Make source name optional in the domain schema, since NBD doesn't use it
-Add a hostName type to the domain schema, and use it instead of genericName, which doesn't include .
-Don't leak host names or ports
-Set the source protocol in qemuParseCommandline

This patch adds network disk support to libvirt/QEMU. The currently
supported protocols are nbd, rbd, and sheepdog. The XML syntax is like
this:

<driver name="qemu" type="raw" />
<source protocol='rbd|sheepdog|nbd' name="...some image identifier...">
<host name="mon1.example.org" port="6000">

Guarantee that outbuf/errbuf are allocated on success, even if to the
empty string. Caller always has to free the result, and empty output
check requires checking if *outbuf=='\0'. Makes the API easier to use
safely. Failure is best effort allocation (some paths, like
out-of-memory, cannot allocate a buffer, but most do), so caller must
free buffer on failure.
* docs/internals/command.html.in: Update documentation.
* src/util/command.c (virCommandSetOutputBuffer)
(virCommandSetErrorBuffer, virCommandProcessIO) Guarantee empty
string on no output.
* tests/commandtest.c (test17): New test.
* docs/internals/command.html.in: Better documentation of buffer

Similarly to deprecating close(), I am now deprecating fclose() and
introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with
VIR_FDOPEN().
Most of the files are opened in read-only mode, so usage of
VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write
mode already had the fclose()< 0 check and I converted those to
VIR_FCLOSE()< 0.
I did not find occurrences of possible double-closed files on the way.
IP addresses and MAC addresses had been defined in the RNG simply as
<text/> meaning that, according to the RNG, any string could go in
there. Of course the C parsing code does a much better job of
validating, but we may as well have this describing the contents
accurately (even though it's currently only used during "make check").
All the other RNG files in libvirt are enclosed within <grammar>. This
commit makes the syntactical changes necessary to make network.rng fit
that pattern. (This is the first step in adding some data type
definitions to network.rng for more exact validation of IP and MAC
addresses).
Formatting changes (indentation) will be done in a subsequent commit,
so that actual changes to the code won't be obscured by whitespace.
* docs/schemas/domain.rng: Fix merge error which left SPICE channel
elements under VNC schema.
* tests/qemuhelptest.c: Add SPICE flag to kvm-83 test
* tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.xml: Add
<memballoon> element
This extends the SPICE XML to allow channel security options
<graphics type='spice' port='-1' tlsPort='-1' autoport='yes'>
<channel name='main' mode='secure'/>
<channel name='record' mode='insecure'/>
</graphics>
Any non-specified channel uses the default, which allows both
secure & insecure usage
* src/conf/domain_conf.c, src/conf/domain_conf.h,
src/libvirt_private.syms: Add XML syntax for specifying per

* src/qemu/qemu_conf.c: Configure channel security with spice
This extends the XML syntax for <graphics> to allow a password
expiry time to be set
eg
<graphics type='vnc' port='5900' autoport='yes' keymap='en-us' passwd='12345' passwdValidTo='2010-04-09T15:51:00'/>
The timestamp is in UTC.

struct containing VNC password
This adds an element
<graphics type='spice' port='5903' tlsPort='5904' autoport='yes' listen='127.0.0.1'/>
This is the bare minimum that should be exposed in the guest
config for SPICE. Other parameters are better handled as per
host level configuration tunables
* docs/schemas/domain.rng: Define the SPICE <graphics> schema
* src/domain_conf.h, src/domain_conf.c: Add parsing and formatting
for SPICE graphics config
* src/qemu_conf.c: Complain about unsupported graphics types

The default location for the XML catalog file, /etc/xml/catalog,

Since bugs due to double-closed file descriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here.
There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were.
I also dare to declare close() as being deprecated in libvirt code base (HACKING).
* docs/formatdomain.html.in: Add memtune element details, added min_guarantee

https://bugzilla.redhat.com/show_bug.cgi?id=623903 documents a qemu
bug that causes libvirt to hang if virt-manager happens to be

is fixed, people need to know how to avoid the issue.
* docs/formatdomain.html.in (Memory balloon device): Mention
model='none'.
This introduces new attribute to filesystem element
to support customizable access mode for mount type.
Valid accessmode are: passthrough, mapped and squash.
Usage:
<filesystem type='mount' accessmode='passthrough'>
<source dir='/export/to/guest'/>
<target dir='mount_tag'/>
</filesystem>
passthrough is the default model if not specified, that's
also the current behaviour.
* include/libvirt/libvirt.h.in: some of the function type description
were broken so they could not be automatically documented
* src/util/event.c docs/apibuild.py: event.c exports one public API

To enable the CPU XML from the capabilities to be pasted directly
into the guest XML with no editing, pick a sensible default for
match and feature policy. The CPU match will be exact and the
feature policy will be require. This should ensure safety for
migration and give DWIM semantics for users
* src/conf/cpu_conf.c: Default to exact match and require policy
* docs/formatdomain.html.in: Document new defaults
This adds a script to generate the todo item page from
bugzilla. This requires a valid username+password for
bugzilla, so it is intended that this only be run on
the libvirt.org website via cron. Normal usage will just

* docs/todo.pl: Script to extract todo items from bugzilla
* docs/todo.cfg-example: Example config file
* docs/sitemap.html.in: Add todo page
* docs/Makefile.am: Generation rules for todo items
This patch adds another example to the nwfilter html page and provides 2 solutions for how to write a filter meeting the given requirements using newly added features.
Since version 4.1 ESX(i) can expose virtual serial devices over TCP.
Add support in the VMX handling code for this, add test cases to cover
it and add links to some documentation.
ESX supports two additional protocols: TELNETS and TLS. Add them to
the list of serial-over-TCP protocols.
The <vcpu cpuset=...> attribute has been available since commit
e193b5dd, but without documentation or RNG validation.
* docs/schemas/domain.rng (vcpu): Further validate cpuset.
* docs/formatdomain.html.in: Document it.
* src/conf/domain_conf.c: Fix typos.
Prior to this patch, the ChangeLog generation was hard coded to use
"awk", when it should have been using the AWK variable set by our
build system.
This breaks compilation on a newly installed OS X system, where the
default path has the Mac (non GNU) awk in the default search PATH
before any installed GNU awk (gawk).
Tweaked the PolicyKit documentation improvement patch submitted
by Patrick Dignan.
Additionally, removed the reference to PolicyKit.conf, which is
no longer used by PolicyKit, plus added a link to the expanded
PolicyKit example page on the wiki.
Added a workable initial page for the libvirt Application
Development Guide, giving the online viewable options +
the available download ones (pdf, epub, srpm).
Added a link to the PDF to the main Downloads page, plus
neatened the html tags throughout the page as they
were a bit of a mess.
Added --enable-compile-warnings=error to the autogen line,
as suggested by Eric Blake.
Xen supports on_crash actions coredump-{destroy,restart}. libvirt
cannot parse config returned by xend that contains either of these
actions
xen52 # xm li -l test | grep on_crash
(on_crash coredump-restart)
xen52 # virsh dumpxml test
error: internal error unknown lifecycle type coredump-restart
This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.
I wrote a patch to add support for listing the Vendor and Model of a
storage pool in the storage pool XML. This would allow vendor
extensions of specific devices. The patch includes a test for the new
attributes as well.

Add documentation for features added a while ago.
* docs/formatdomain.html.in (Time keeping): Update documentation
of <clock> element to match 0.8.0 addition.
The balloon device is automatically added to qemu guests if supported,
but it may be useful to desactivate it. The simplest to not change the
existing behaviour is to allow
<memballoon type="none"/>
as an extra option to desactivate it (it is automatically added if the
memballoon construct is missing for the domain).
The following simple patch just adds the extra option and does not
change the default behaviour but avoid creating a balloon device if
type="none" is used.
* docs/schemas/domain.rng: add the extra type attribute value
* src/conf/domain_conf.c src/conf/domain_conf.h: add the extra enum
value
* src/qemu/qemu_conf.c: if enum is NONE, don't activate the device,
i.e. don't pass the args to qemu/kvm
Now a vpx:// connection has an explicitly specified host. This
allows to enabled several functions for a vpx:// connection
again, like host UUID, hostname, general node info, max vCPU
count, free memory, migration and defining new domains.
Lookup datacenter, compute resource, resource pool and host
system once and cache them. This simplifies the rest of the
code and reduces overall HTTP(S) traffic a bit.
esx:// and vpx:// can be mixed freely for a migration.
Ensure that migration source and destination refer to the
same vCenter. Also directly encode the resource pool and
host system object IDs into the migration URI in the prepare
function. Then directly build managed object references in
the perform function instead of re-looking up already known
information.
All <console> devices now export a <target> type attribute. QEMU defaults
to 'serial', UML defaults to 'uml, xen can be either 'serial' or 'xen'
depending on fullvirt. Understandably there is lots of test fallout.
This will be used to differentiate between a serial vs. virtio console for
QEMU.

Add a new element to the <os> block:
<bootmenu enable="yes|no"/>
Which maps to -boot,menu=on|off on the QEMU command line.
I decided to use an explicit 'enable' attribute rather than just make the
bootmenu element boolean. This allows us to treat lack of a bootmenu element
as 'use hypervisor default'.
Add a pointer to the primary context of a connection and use it in all
driver functions that don't dependent on the context type. This includes
almost all functions that deal with a virDomianPtr. Therefore, using
a vpx:// connection allows you to perform all the usual domain related
actions like start, destroy, suspend, resume, dumpxml etc.
Some functions that require an explicitly specified ESX server don't work
yet. This includes the host UUID, the hostname, the general node info, the
max vCPU count and the free memory. Also not working yet are migration and
defining new domains.
Thanks to DV for knocking together the Relax-NG changes
quickly for me.
Changes since v1:
- Change the domain.rng to correspond to the new schema

To allow compatibility with older QEMU PCI device slot assignment
it is necessary to explicitly track the balloon device in the

guests by default.
* docs/schemas/domain.rng: Add <memballoon> element

By specifying <vendor> element in CPU requirements a guest can be
restricted to run only on CPUs by a given vendor. Host CPU vendor is
also specified in capabilities XML.
The vendor is checked when migrating a guest but it's not forced, i.e.,
guests configured without <vendor> element can be freely migrated.
(EXTRA_DIST): Remove redundant listing of xml files.
(html/%-%.html, html/%-virterror.html, %-api.xml, %-refs.xml):
Rewrite with...
(python_generated_files): ...new macro, since make didn't see
through the dependency chain correctly otherwise.
Also don't abuse the disk driver name to specify the SCSI controller
model anymore:
<driver name='buslogic'/>
Use the newly added model attribute of the controller element for this:
<controller type='scsi' index='0' model='buslogic'/>
The disk driver name approach is deprecated now, but still works for
backward compatibility reasons.
Update the documentation and tests accordingly.
Fix usage of the words controller and id in the VMX handling code. Use
controller, bus and unit properly.
According to docs/formatdomain.html.in, "The boot element can be
repeated multiple times to setup a priority list of boot devices to try
in turn." The Relax-NG schema required / allowed exactly one entry.

This patch adds an optional XML attribute to a nwfilter rule to give the user control over whether the rule is supposed to be using the iptables state match or not. A rule may now look like shown in the XML below with the statematch attribute either having value '0' or 'false' (case-insensitive).

dstportstart='100' dstportend='1111'/>
</rule>
[...]
I am also extending the nwfilter schema and add this attribute to a test case.
The virtio serial changes broke the test suite because they forgot
to add the new address attribute to the domain XML schema. The
xml2xml test also broke because the XML no longer roundtrips. This
is due to testing of auto-addition of <controller> elements. Split
that test case off into a separate XML file to avoid breakage
* docs/schemas/domain.rng: Allow port number for virtio serial addresses
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Revert to

complex test case for auto-controller addition for xml2argv test
* tests/qemuxml2argvtest.c: Add channel-virtio-auto test
Otherwise, 'make check' in the python dir tries to reference a file in
docs that is built by 'make' but not by 'make check'.

This patch parses the following two XML descriptions, one for
802.1Qbg and one for 802.1Qbh, and stores the data internally.
The actual triggering of the switch setup protocol has not been
implemented here but the relevant code to do that should go into
the functions associatePortProfileId() and disassociatePortProfileId().
<interface type='direct'>
<source dev='eth0.100' mode='vepa'/>
<model type='virtio'/>
<virtualport type='802.1Qbg'>
<parameters managerid='12' typeid='0x123456' typeidversion='1'
instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/>
</virtualport>
<filterref filter='clean-traffic'/>
</interface>
<interface type='direct'>
<source dev='eth0.100' mode='vepa'/>
<model type='virtio'/>
<virtualport type='802.1Qbh'>
<parameters profileid='my_profile'/>
</virtualport>
</interface>
I'd suggest to use this patch as a base for triggering the setup
protocol with the 802.1Qb{g|h} switch.
Several rounds of changes were made to this patch. The
following is a list of these changes.
- Renamed structure virVirtualPortProfileDef to virVirtualPortProfileParams
as per Daniel Berrange's request
- Addressing Daniel Berrange's comments:
- removing macvtap.h's dependency on domain_conf.h by
moving the virVirtualPortProfileDef structure into macvtap.h
and not passing virtDomainNetDefPtr to any functions in
macvtap.c
- Addressed most of Chris Wright's comments:
- indicating error in case virtualport XML node cannot be parsed
properly
- parsing hex and decimal numbers using virStrToLong_ui() with
parameter '0' for base
- tgifname (target interface name) variable wasn't necessary
to pass to openMacvtapTap function anymore
- assigning the virtual port data structure to the virDomainNetDef
only if it was previously parsed
- make sure that the error code returned by openMacvtapTap() is a negative n
in case the associatePortProfileId() function failed.
- renaming vsi in the XML to virtualport
- replace all occurrences of vsi in the source as well
- removing mode and MAC address parameters from the functions that
will communicate with the hareware diretctly or indirectly
- moving the associate and disassociate functions to the end of the
file for subsequent patches to easier make them generally available
for export
- passing the macvtap interface name rather than the link device since
this otherwise gives funny side effects when using netlink messages
where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev
all of a sudden gets the MAC address of the macvtap interface.
- Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case
we wanted to use hook scripts for the setup and so the setup doesn't fail
here.
- if instance ID UUID is not supplied it will automatically be generated
- adapted schema to make instance ID UUID optional
- added test case
- parser and XML generator have been separated into their own
functions so they can be re-used elsewhere (passthrough case
for example)
- Adapted XML parser and generator support the above shown type
(802.1Qbg, 802.1Qbh).
- Adapted schema to above XML
- Adapted test XML to above XML
- Passing through the VM's UUID which seems to be necessary for
802.1Qbh -- sorry no host UUID
- adding virtual function ID to association function, in case it's
necessary to use (for SR-IOV)
Allow for a host UUID in the capabilities XML. Local drivers
will initialize this from the SMBIOS data. If a sanity check
shows SMBIOS uuid is invalid, allow an override from the
libvirtd.conf configuration file
* daemon/libvirtd.c, daemon/libvirtd.conf: Support a host_uuid
configuration option
* docs/schemas/capability.rng: Add optional host uuid field
* src/conf/capabilities.c, src/conf/capabilities.h: Include
host UUID in XML
* src/libvirt_private.syms: Export new uuid.h functions
* src/lxc/lxc_conf.c, src/qemu/qemu_driver.c,
src/uml/uml_conf.c: Set host UUID in capabilities
* src/util/uuid.c, src/util/uuid.h: Support for host UUIDs
* src/node_device/node_device_udev.c: Use the host UUID functions
* tests/confdata/libvirtd.conf, tests/confdata/libvirtd.out: Add
new host_uuid config option to test
* docs/hacking.html.in: Use the "curly braces" section from coreutils'
HACKING, adapting for libvirt's different formatting style.
* HACKING: Sync from the above, still mostly manually.
So far the references to other filters needed to appear before filtering
rules. With the below patch they can now appear in any order.
Also I forgot to add a couple of 'rarp's.
This patch adds support for the RARP protocol. This may be needed due to
qemu sending out a RARP packet (at least that's what it seems to want to
do even though the protocol id is wrong) when migration finishes and
we'd need a rule to let the packets pass.
Unfortunately my installation of ebtables does not understand -p RARP
and also seems to otherwise depend on strings in /etc/ethertype
translated to protocol identifiers. Therefore I need to pass -p 0x8035
for RARP. To generally get rid of the dependency of that file I switch
all so far supported protocols to use their protocol identifier in the
-p parameter rather than the string.
I am also extending the schema and added a test case.
changes from v1 to v2:
- added test case into patch
With this patch I want to enable hex number inputs in the filter XML. A
number that was entered as hex is also printed as hex unless a string
representing the meaning can be found.
I am also extending the schema and adding a test case. A problem with
the DSCP value is fixed on the way as well.
Changes from V1 to V2:
- using asHex boolean in all printf type of functions to select the
output format in hex or decimal format
* configure.ac docs/news.html.in libvirt.spec.in src/libvirt_public.syms:
updates for release of 0.8.0
* po/*.po po/libvirt.pot: updated a lar set of localizations, and merge
the messages
Extend tests to cover all SCSI controller types and document the
new type.
The lsisas1068 SCSI controller type was added in ESX 4.0. The VMX
parser reports an error when this controller type is present. This
makes virsh dumpxml fail for every domain that uses this controller
type.
This patch fixes this and adds lsisas1068 to the list of accepted
SCSI controller types.
Reported by Jonathan Kelley.
This patch adds a relaxng nwfilter schema along with a test that
verifies all the test output XML against the schema. The input XMLs
contain a lot of intentional out-of-range values that make them fail the
schema verification, so I am not verifying against those.
The clock timer XML is being updated in the following ways (based on
further off-list discussion that was missed during the initial
implementation):
1) 'wallclock' is changed to 'track', and the possible values are 'boot'
(corresponds to old 'host'), 'guest', and 'wall'.
2) 'mode' has an additional value 'smpsafe'
3) when tickpolicy='catchup', there can be an optional sub-element of
timer called 'catchup':
<catchup threshold=123 slew=120 limit=10000/>
Those three values are all longs, always optional, and if they are present,
they are positive. Internally, 0 indicates "unspecified".
* docs/schemas/domain.rng: updated RNG definition to account for changes
* src/conf/domain_conf.h: change the C struct and enums to match changes.
* src/conf/domain_conf.c: timer parse and format functions changed to
handle the new selections and new element.
* src/libvirt_private.syms: *TimerWallclock* changes to *TimerTrack*
* src/qemu/qemu_conf.c: again, account for Wallclock --> Track change.
* cfg.mk (sc_prohibit_test_minus_ao): Also check for [.
* docs/Makefile.am (%.html, html/index.html): Avoid non-portable
test usage.
* libvirt.spec.in (%post): Likewise.
* tools/virt-pki-validate.in (servercert.pem): Likewise.
* configure.ac (LOGNAME): Use test, not [, in files processed by
autoconf.
Detected by Matthias Bolte.
timers are sub-elements of clocks. A clock can have zero or more
instances of timer. Within the timer, only the name attribute is
required; all other attributes are optional.
A simpler representation of a timer element is:
<timer name='platform|pit|rtc|hpet|tsc'
wallclock='host|guest'
tickpolicy='delay|catchup|merge|discard'
frequency='123'
mode='auto|native|emulate|paravirt'
present='yes|no'/>
frequency is a ulong. All other attributes are simple enums.
* Fixes per feedback from Dan and Daniel
* Added test datafiles
* Re-disabled JSON flags
* Added code to print the error policy attribute when generating XML
* Re-add empty tag
In the documentation mention that the direct device support is there
since libvirt 0.7.7. A Linux kernel 2.6.34 is required for macvtap to be
available as standard device.
With N_() in place, we can use it for a smaller file.
* doc/api-extension/0008-Step-8-of-8-Add-virsh-support.patch:
Replace all uses of gettext_noop with N_.
* tools/virsh.c: Likewise, throughout the file.
* configure.ac libvirt.spec.in: update with new version
* docs/news.html.in: add list of changes in 0.7.7
* po/*po*: updated spanish and russian localisations, rebuilt
This extends the XML to allow for
<clock offset='timezone' timezone='Europe/Paris'/>
This is useful if the admin has not configured any timezone on the
host OS, but still wants to synchronize a guest to a specific one.
* src/conf/domain_conf.h, src/conf/domain_conf.c: Support extra
'timezone' attribute on clock configuration
* docs/schemas/domain.rng: Add 'timezone' attribute
* src/xen/xend_internal.c, src/xen/xm_internal.c: Reject configs
with a configurable timezone
This introduces a third option for clock offset synchronization,
that allows an arbitrary / variable adjustment to be set. In
essence the XML contains the time delta in seconds, relative to
UTC.
<clock offset='variable' adjustment='123465'/>
The difference from 'utc' mode, is that management apps should
track adjustments and preserve them at next reboot.
* docs/schemas/domain.rng: Schema for new clock mode
* src/conf/domain_conf.c, src/conf/domain_conf.h: Parse
new clock time delta
* src/libvirt_private.syms, src/util/xml.c, src/util/xml.h: Add
virXPathLongLong() method
Add missing rule to build html/libvirt-libvirt.html.
Use a GNU Make pattern rule to avoid running apibuild.py once
for each out-of-date target, in a parallel build.
* docs/Makefile.am
* docs/Makefile.am (libvirt-api.xml libvirt-refs.xml): Generalize
apibuild.py to work in a non-srcdir build. Pass "srcdir" to it.
* docs/apibuild.py (rebuild): Honor the $srcdir envvar.
* docs/Makefile.am (MAINTAINERCLEANFILES): Use this variable
for generated-and-distributed files, not "CLEANFILES".
Besides, "make clean" and "make distclean" should not delete
distributed files.
Add support for virtio-serial by defining a new 'virtio' channel target type
and a virtio-serial controller. Allows the following to be specified in a
domain:
<controller type='virtio-serial' index='0' ports='16' vectors='4'/>
<channel type='pty'>
<target type='virtio' name='org.linux-kvm.port.0'/>
<address type='virtio-serial' controller='0' bus='0'/>
</channel>
* docs/schemas/domain.rng: Add virtio-serial controller and virtio
channel type.
* src/conf/domain_conf.[ch]: Domain parsing/serialization for
virtio-serial controller and virtio channel.
* tests/qemuxml2xmltest.c
tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: add domain xml
parsing test
* src/libvirt_private.syms src/qemu/qemu_conf.c:
virDomainDefAddDiskControllers() renamed to
virDomainDefAddImplicitControllers()
The current schema is more permissive than the XML parsing code in
libvirt. Precisely, 'match' attribute is optional in schema while in
reality its use is bound to <model> element:
- <cpu> element without 'match' attribute is allowed only if <topology>
element is the only child element of <cpu>
- <cpu> element with 'match' attribute requires <model> element to be
present; <topology> and <feature> elements are optional

When attaching a USB host device based on vendor/product, libvirt
will resolve the vendor/product into a device/bus pair. This means
that when printing XML we should allow device/bus info to be printed
at any time if present
* src/conf/domain_conf.c, docs/schemas/domain.rng: Allow USB device
bus info alongside vendor/product
Allows the initiator to use a variety of IQNs rather than just the
system IQN when creating iSCSI pools.
* docs/schemas/storagepool.rng: extends the syntax with <iqn name="..."/>
* src/conf/storage_conf.[ch]: read and stores the iqn name
* src/storage/storage_backend_iscsi.[ch]: implement the IQN selection
when detected
The RNG now supports IPv6 and bonds attached to bridges, along with
some other minor tweaks. All test files from netcf have been copied to
the test directory and added to the xml2xml and schema tests (and they
all pass, of course ;-)
Currently CPU topology may only be specified together with CPU model:
<cpu match='exact'>
<model>name</model>
<topology sockets='1' cores='2' threads='3'/>
</cpu>
This patch allows for CPU topology specification without the need for
also specifying CPU model:
<cpu>
<topology sockets='1' cores='2' threads='3'/>
</cpu>
'match' attribute and 'model' element are made optional with the
restriction that 'match' attribute has to be set when 'model' is
present.

Although the serial, parallel, chanel, input & fs devices do
not have PCI address info, they can all have device aliases.
Thus it neccessary to associate the virDomainDeviceInfo data
with them all.
* src/conf/domain_conf.c, src/conf/domain_conf.h: Add hooks for
parsing / formatting device info for serial, parallel, channel
input and fs devices.
* docs/schemas/domain.rng: Associate device info with character
devices, input & fs device
The latter is not officially "wrong", but *is* terribly anachronistic.
I think automake documentation or comments call that syntax obsolescent.
* cfg.mk (_makefile_at_at_check_exceptions): Exempt @SCHEMADIR@
and @SYSCONFDIR@ uses -- there are no Makefile variables for those.
* docs/Makefile.am: Use $(INSTALL), not @INSTALL@.
* examples/dominfo/Makefile.am: Similar.

This augments virDomainDevice with a <controller> element
that is used to represent disk controllers (e.g., scsi
controllers). The XML format is given by
<controller type="scsi" index="<num>">
<address type="pci" domain="0xNUM" bus="0xNUM" slot="0xNUM"/>
</controller>
where type denotes the disk interface (scsi, ide,...), index
is an integer that identifies the controller for association
with disks, and the <address> element specifies the controller
address on the PCI bus as described in previous commits
The address element can be omitted; in this case, an address
will be assigned automatically.
Most of the code in this patch is from Wolfgang Mauerer's
previous disk controller series
* docs/schemas/domain.rng: Define syntax for <controller>
XML element
* src/conf/domain_conf.c, src/conf/domain_conf.h: Define
virDomainControllerDef struct, and routines for parsing
and formatting XML
* src/libvirt_private.syms: Add virDomainControllerInsert
and virDomainControllerDefFree
Add the virDomainDeviceAddress information to the sound, video
and watchdog devices. This means all of them gain the new XML
element
<address .... />
This brings them upto par with disk/net/hostdev devices which
already have address info
* src/conf/domain_conf.h: Add virDomainDeviceAddress to sound,
video & watchdog device struts.
* src/conf/domain_conf.c: Hook up parsing/formatting for
virDomainDeviceAddress in sound, video & watchdog devices
* docs/schemas/domain.rng: Associate device address info
with sound, video & watchdog
Introduce a new structure
struct _virDomainDeviceDriveAddress {
unsigned int controller;
unsigned int bus;
unsigned int unit;
};
and plug that into virDomainDeviceAddress and generates XML that
looks like
<address type='drive' controller='1' bus='0' unit='5'/>
This syntax will be used by the QEMU driver to explicitly control
how drives are attached to the bus
* src/conf/domain_conf.h, src/conf/domain_conf.c: Parsing and
formatting of drive addresses
* docs/schemas/domain.rng: Define new address format for drives
All guest devices now use a common device address structure
summarized by:
enum virDomainDeviceAddressType {
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_NONE,
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI,
};
struct _virDomainDevicePCIAddress {
unsigned int domain;
unsigned int bus;
unsigned int slot;
unsigned int function;
};
struct _virDomainDeviceInfo {
int type;
union {
virDomainDevicePCIAddress pci;
} addr;
};
This replaces the anonymous structs in Disk/Net/Hostdev data
structures. Where available, the address is *always* printed
in the XML file, instead of being hidden in the internal state
file.
<address type='pci' domain='0x0000' bus='0x1e' slot='0x07' function='0x0'/>
The structure definition is based on Wolfgang Mauerer's disk
controller patch series.
* docs/schemas/domain.rng: Define the <address> syntax and
associate it with disk/net/hostdev devices
* src/conf/domain_conf.h, src/conf/domain_conf.c,
src/libvirt_private.syms: APIs for parsing/formatting address
information. Also remove the QEMU specific 'pci_addr' attributes
* src/qemu/qemu_driver.c: Replace use of 'pci_addr' attrs with
new standardized format.
* docs/Makefile.am (uninstall-local): Separate $$f from preceding
dir name with a "/" and use $$(basename $$f) rather than $$f, since
some values of $$f are prefixed with devhelp/.
The MAC addresses with 00:50:56 prefix are split into several ranges:
00:50:56:00:00:00 - 00:50:56:3f:ff:ff 'static' range (manually assigned)
00:50:56:80:00:00 - 00:50:56:bf:ff:ff 'vpx' range (assigned by a VI Client)
Erroneously the 'vpx' range was assumed to be larger and to occupy the
remaining addresses of the 00:50:56 prefix that are not part of the 'static'
range.
00:50:56 was used as prefix for generated MAC addresses, this is not possible
anymore, because there are gaps in the allowed ranges. Therefore, change the
prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway.
Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option
to false in case the MAC address doesn't fall into any predefined range.
* docs/drvesx.html.in: update website accordingly
* src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29
* src/esx/esx_vmx.c: fix MAC address range handling and allow arbitrary MAC
addresses
* tests/vmx2xml*, tests/xml2vmx*: add some basic MAC address range tests
