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>

channel type.

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@.

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
XML schema for CPU flags
Firstly, CPU topology and model with optional features have to be
advertised in host capabilities:
<host>
<cpu>
<arch>ARCHITECTURE</arch>
<features>
<!-- old-style features are here -->
</features>
<model>NAME</model>
<topology sockets="S" cores="C" threads="T"/>
<feature name="NAME"/>
</cpu>
...
</host>
Secondly, drivers which support detailed CPU specification have to
advertise
it in guest capabilities:
<guest>
...
<features>
<cpuselection/>
</features>
</guest>
And finally, CPU may be configured in domain XML configuration:
<domain>
...
<cpu match="MATCH">
<model>NAME</model>
<topology sockets="S" cores="C" threads="T"/>
<feature policy="POLICY" name="NAME"/>
</cpu>
</domain>
Where MATCH can be one of:
- 'minimum' specified CPU is the minimum requested CPU
- 'exact' disable all additional features provided by host CPU
- 'strict' fail if host CPU doesn't exactly match
POLICY can be one of:
- 'force' turn on the feature, even if host doesn't have it
- 'require' fail if host doesn't have the feature
- 'optional' match host
- 'disable' turn off the feature, even if host has it
- 'forbid' fail if host has the feature
'force' and 'disable' policies turn on/off the feature regardless of its
availability on host. 'force' is unlikely to be used but its there for
completeness since Xen and VMWare allow it.
'require' and 'forbid' policies prevent a guest from being started on a host
which doesn't/does have the feature. 'forbid' is for cases where you disable
the feature but a guest may still try to access it anyway and you don't want
it to succeed.
'optional' policy sets the feature according to its availability on host.
When a guest is booted on a host that has the feature and then migrated to
another host, the policy changes to 'require' as we can't take the feature
away from a running guest.
Default policy for features provided by host CPU but not specified in domain
configuration is set using match attribute of cpu tag. If 'minimum' match is
requested, additional features will be treated as if they were specified
with 'optional' policy. 'exact' match implies 'disable' policy and 'strict'
match stands for 'forbid' policy.
* docs/schemas/capability.rng docs/schemas/domain.rng: extend the
RelaxNG schemas to add CPU flags support
The description mismatched the actual structure since the video element
was introduced. The nvram attribute is actually called vram. Specify the
unit of the vram attribute.
The owner and group in the documentation examples were confusingly given as
'0744'. They should be numeric uid and gid. Changed the examples to use the
default uid and gid assigned to qemu in F12.
* docs/formatstorage.html.in: Change example owner and group in volume XML
Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.
* docs/ChangeLog.xsl docs/newapi.xsl docs/site.xsl: change all
stylesheets to output UTF-8 HTML instead of ISO Latin 1 which was
breaking on some people names.
Introduce a new type="dir" mode for <disks> that allows use of
QEMU's virtual FAT block device driver. eg
<disk type='dir' device='floppy'>
<source dir='/tmp/test'/>
<target dev='fda' bus='fdc'/>
<readonly/>
</disk>
gets turned into
-drive file=fat:floppy:/tmp/test,if=floppy,index=0

* src/qemu/qemu_conf.c: Support generating fat:/some/dir type
disk args
* src/security/security_selinux.c: Temporarily skip labelling

0.7.3 was broken
* configure.in docs/news.html.in: release of 0.7.4
* configure.in libvirt.spec.in: require netcf >= 0.1.4
* src/Makefile.am: node_device/node_device_udev.h was missing from
NODE_DEVICE_DRIVER_UDEV_SOURCES breaking compilation on platforms with
udev
For backward compatibility we used to add the tty path as
a tty attribute on console of type pty, duplicating the value
now found in source/@path, but the Relax-NG grammar wasn't
extended for this
<console type='pty' tty='/dev/pts/8'>
<source path='/dev/pts/8'/>
<target port='0'/>
</console>
* docs/schemas/domain.rng: allow an optional tty attribute

* docs/drivers.html.in: list the ESX driver
* docs/drvesx.html.in: the new ESX driver documentation
* docs/hvsupport.html.in: add the ESX driver to the matrix
* docs/index.html.in, docs/sitemap.html.in: list the ESX driver

* docs/site.xsl: use matching public identifier
* docs/formatdomain.html.in: refactors the existing character device
documentation to make it explicit which directives configure the guest
interface, and which configure the host interface.

* src/qemu/qemu_conf.c: Add argument output for channel
* tests/qemuxml2(argv|xml)test.c: Add test for <channel> domain syntax
This patch adds an optional attribute to the <bootp> tag, that
allows to specify a TFTP server address other than the address of
the DHCP server itself.
This can be used to forward the BOOTP settings of the host down to the
guest. This is something that configurations such as Xen's default
network achieve naturally, but must be done manually for NAT.
* docs/formatnetwork.html.in: Document new attribute.
* docs/schemas/network.rng: Add it to schema.
* src/conf/network_conf.h: Add it to struct.
* src/conf/network_conf.c: Add it to parser and pretty printer.
* src/network/bridge_driver.c: Put it in the dnsmasq command line.
* tests/networkxml2xmlin/netboot-proxy-network.xml
tests/networkxml2xmlout/netboot-proxy-network.xml
tests/networkxml2xmltest.c: add new tests
* src/conf/storage_conf.c src/conf/storage_conf.h: extend the enums
and values
* docs/schemas/storagepool.rng: add to the list of storage pool type
formats
- mpath pools weren't listed
- scsi pools were missing an adapter section
- iscsi pools were missing an auth section
- Logical pools do not require a source name to be specified
The domain/os/type element may have an arch specified without having
a machine variant specified. In fact, this is what python-virtinst
does when defining a guest.
* docs/schemas/domain.rng: allow missing machine type
Removes some auto-generated files still under version control.
It also moves the rule for generating NEWS into the Makefile.am
that's in the same directory as the output file to avoid confusion
* docs/libvirt-api.xml, docs/libvirt-refs.xml, NEWS: Remove
auto-generated files from source control
* Makefile.am: Add rule for generating NEWS file
* docs/Makefile.am: Remove rule for generating NEWS file
Simplify the doTunnelMigrate() method by pulling out the code
which opens/closes the virConnectPtr object into a parent
method
* qemu/qemu_driver.c: Add doPeer2PeerMigrate which then calls
doTunnelMigrate with dconn & dom_xml
* docs/drvqemu.html.in: include documentation for AppArmor sVirt
confinement
* examples/apparmor/TEMPLATE examples/apparmor/libvirt-qemu
examples/apparmor/usr.lib.libvirt.virt-aa-helper
examples/apparmor/usr.sbin.libvirtd: example templates and

The devhelp/ directory files depend on libvirt-api.xml being
uptodate, but automake always processes SUBDIRS before the
current directory. So devhelp would be built and then the
libvirt-api.xml re-build, invalidating the devhelp data again.
To fix this all the rules for devhelp are moved directly
into the docs/Makefile.am allowing make to see the global
dependancy chain and thus build things in the correct order
* docs/Makefile.am: Add rules for devhelp rebuild
* docs/devhelp/Makefile.am: Remove devhelp rebuild
* configure.in: Remove docs/devhelp/Makefile.am
Implementation of tunnelled migration, using a Unix Domain Socket

The python method help docs are copied across from the C
funtion comments, but in the process all line breaks and
indentation was being lost. This made the resulting text
and code examples completely unreadable. Both the API
doc extractor and the python generator were destroying
whitespace & this fixes them to preserve it exactly.
* docs/apibuild.py: Preserve all whitespace when extracting
function comments. Print function comment inside a <![CDATA[
section to fully preserve all whitespace. Look for the
word 'returns' to describe return values, instead of 'return'
to avoid getting confused with code examples including the
C 'return' statement.
* python/generator.py: Preserve all whitespace when printing
function help docs
* src/libvirt.c: Change any return parameter indicated by
'return' to be 'returns', to avoid confusing the API extractor
* docs/libvirt-api.xml: Re-build for fixed descriptions
Currently, libvirtd will start a dnsmasq process for the virtual
network, but (aside from killing the dnsmasq process and replacing it),
there's no way to define tftp boot options.
This change introduces the appropriate tags to the dhcp configuration:
<network>
<name>default</name>
<bridge name="virbr%d" />
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<tftp root="/var/lib/tftproot" />
<dhcp>
<range start="192.168.122.2" end="192.168.122.254" />
<bootp file="pxeboot.img"/>
</dhcp>
</ip>
</network>
When the attributes are present, these are passed to the
arguments to dnsmasq:
dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^
from <tftp /> from <bootp />
At present, only local tftp servers are supported (ie, dnsmasq runs as
the tftp server), but we could improve this in future by adding a
server= attribute.
