This function sets the running domain definition as transient, by reparsing
the persistent config and assigning it to newDef. This ensures that any
changes made to the running definition and not the persistent config are
discarded when the VM is shutdown.
I am trying to use a qcow image with libvirt where the backing 'file' is a
qemu-nbd server. Unfortunately virDomainDiskDefForeachPath() assumes that
backingStore is always a real file so something like 'nbd:0:3333' is rejected
because a file with that name cannot be accessed. Note that I am not worried
about directly using nbd images. That would require a new disk type with XML
markup, etc. I only want it to be permitted as a backingStore
The following patch implements danpb's suggestion:

src/xen/xend_internal.c, src/xen/xm_internal.c: Update for changed
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

During a shutdown/restart cycle libvirtd forgot the macvtap device name that it had created on behalf of a VM so that a stale macvtap device remained on the host when the VM terminated. Libvirtd has to actively tear down a macvtap device and it uses its name for identifying which device to tear down.
The solution is to not blank out the <target dev='...'/> completely, but only blank it out on VMs that are not active. So, if a VM is active, the device name makes it into the XML and is also being parsed. If a VM is not active, the device name is discarded.
The virSocketParse method was not doing any error reporting
which meant the true cause of the problem was lost. Remove
all error reporting from callers, and push it into virSocketParse

* src/conf/domain_conf.c, src/conf/network_conf.c,
src/network/bridge_driver.c: Remove error reporting in
callers of virSocketParse
The getnameinfo() function is more flexible than inet_ntop()
avoiding the need to if/else the code based on socket family.
Also make it support UNIX socket addrs and allow inclusion
of a port (service) address. Finally do proper error reporting
via normal APIs.

The virSocketParseAddr function was accepting any AF_* constant
and using that to set the ai_flags field in struct addrinfo.
This is invalid, since address families must go in the ai_family
field of the struct.
* src/util/network.c: Fix handling of address family
* src/conf/network_conf.c, src/network/bridge_driver.c: Pass
AF_UNSPEC instead of relying on it being 0.
Some operations on socket addresses need to know the length of
the sockaddr struct for the particular address family. This
info was being discarded when passing around virSocketAddr
instances. Turn it from a union into a struct containing
union+socklen_t fields, so length is always kept around.

Although this patch adds a distinction between maximum vcpus and
current vcpus in the XML, the values should be identical for all

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).
This introduces new attribute to filesystem element
to support customizable access mode for mount type.
Valid accessmode are: passthrough, mapped and squash.
Usage:

passthrough is the default model if not specified, that's
also the current behaviour.

ESX supports two additional protocols: TELNETS and TLS. Add them to
the list of serial-over-TCP protocols.

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.
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
When parsing hostdev, the following message would be emitted:

However, alias is appropriately parsed in
virDomainDeviceInfoParseXML anyway. Disable the error message
in the initial XML parsing loop.

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'.
This patch adds namespace XML parsers to be hooked into
the main domain parser. This allows for individual hypervisor
drivers to add per-namespace XML into the main domain XML.

To allow compatibility with older QEMU PCI device slot assignment
it is necessary to explicitly track the balloon device in the
XML. This introduces a new device
<memballoon model='virtio|xen'/>
It can also have a PCI address, auto-assigned if necessary.
The memballoon will be automatically added to all Xen and QEMU
guests by default.
* docs/schemas/domain.rng: Add <memballoon> element
* src/conf/domain_conf.c, src/conf/domain_conf.h: parsing

balloon device to Xen/QEMU if none exists in XML

There is duplicated code which iterates over disk backing stores
performing some action. Provide a convenient helper for doing

src/libvirt_private.syms: Add virDomainDiskDefForeachPath()
The parallel, serial, console and channel devices are all just
character devices. A lot of code needs todo the same thing to

The domain XML parsing code autogenerates disk address and
controller elements when they are not explicitly specified.
The code assumes a narrow SCSI bus (7 units per bus). ESX
uses a wide SCSI bus (16 units per bus).
This is a step towards controller support for the ESX driver.
The domain parsing code would auto-add a virtio serial controller
if it saw any virtio serial channel defined. Unfortunately it
always added a controller with index=0, even if the channel address
specified an index != 0. It only added one controller, even if
multiple controllers were referenced by channels. Finally, it let
the ports+vectors parameters initialize to zero instead of -1, which
prevented the controllers accepting any ports.
* src/conf/domain_conf.c: Initialize ports+vectors when adding
virtio serial controllers. Add all neccessary virtio serial
controllers, instead of hardcoding controller 0

To ensure that the device addressing scheme is stable across
hotplug/unplug, all virtio serial channels needs to have an
associated port number in their address. This is then specified
to QEMU using the nr=NNN parameter

for port number in vioserial address types.
* src/qemu/qemu_conf.c: Set 'nr=NNN' parameter with virtio

Since the macvtap device needs active tear-down and the teardown logic
is based on the interface name, it can happen that if for example 1 out
of 3 interfaces was successfully created, that during the failure path
the macvtap's target device name is used to tear down an interface that
is doesn't own (owned by another VM).
So, in this patch, the target interface name is reset so that there is
no target interface name and the interface name is always cleared after
a tear down.

The attached patch moves virVirtualPortProfileFormat below the #ifndef

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'

<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)
We shouldn't be checking validity in domain_conf, since
it can be used by multiple different hosts and hypervisors.
Remove the check completely.

We need to be able to assign new def to an existing virDomainObj which
is already locked. This patch factors out the relevant code from
virDomainAssignDef into virDomainObjAssignDef.
<hostdev> address parsing previously attempted to detect the number
base: currently it is hardcoded to base 16, which can break PCI
assignment via virt-manager. Revert to the previous behavior.

* virStorageEncryptionFormat is called from both
virDomainDiskDefFormat and virStorageVolTargetDefFormat. The proper
indentation in the generated XML depends on the caller. My earlier
patch to fix the incorrect indentation for the domain XML broke the
indentation for the storage XML. This patch adopts Laine's
suggestion of requring the caller of virStorageEncryptionFormat to
provide an unsigned int with the number of spaces the output should
be indented. The patch modifies both callers to provide the
additional argument.

While playing around with def/newDef with the qemu code,
I noticed that newDef was *always* getting set to a value,
even when I didn't redefine the domain. I think the problem
is the virDomainLoadConfig is always doing virDomainAssignDef
regardless of whether the domain already exists in the hashtable.
In turn, virDomainAssignDef is assigning the definition (which
is actually a duplicate) to newDef. Fix this so that newDef stays
NULL until we actually have a new def.

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

When a domain is defined on host1, migrated to host2 and then migrated
back to host1, its current configuration would overwrite the libvirtd's
in-memory copy of persistent configuration of that domain. This is not
desired as we want to preserve the persistent configuration untouched.
This patch introduces new 'live' parameter to virDomainAssignDef.
Passing 'true' for 'live' means the configuration passed to
virDomainAssignDef describes a configuration of live instance of the
domain. This applies for saved domains which are being restored or for
incoming domains during migration.
All callers have been changed to pass the appropriate value.

To find out where the net type 'direct' needs to be handled I introduced

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.

The difference from 'utc' mode, is that management apps should
track adjustments and preserve them at next reboot.

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()
Remove virDomainDevicePCIAddressEqual and virDomainDeviceDriveAddressEqual,
which are defined but not used anywhere.
* src/conf/domain_conf.[ch] src/libvirt_private.syms: Remove
virDomainDevicePCIAddressEqual and virDomainDeviceDriveAddressEqual.
This part adds support to domain_conf.{c|h} for parsing the new
interface XML of type 'direct'. The parsed mode is now stored as
an int.
* src/conf/domain_conf.c src/conf/domain_conf.h: extend parsing code
* src/util/macvtap.h: empty header to not break compilation
The virConnectPtr is no longer required for error reporting since
that is recorded in a thread local. Remove use of virConnectPtr
from all APIs in cpu_conf.{h,c} and update all callers to
match

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
The current way of assigning names to the host network backend and
NIC device in QEMU was over complicated, by varying naming scheme
based on the NIC model and backend type. This simplifies the naming
to simply be 'net0' and 'hostnet0', allowing code to easily determine
the host network name and vlan based off the primary device alias
name 'net0'. This in turn allows removal of alot of QEMU specific
code from the XML parser, and makes it easier to assign new unique
names for NICs that are hotplugged
* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove hostnet_name
and vlan fields from virNetworkDefPtr
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c:
Use a single network alias naming scheme regardless of NIC type
or backend type. Determine VLANs from the alias name.

tests/qemuxml2argvdata/qemuxml2argv-net-virtio-device.args,
tests/qemuxml2argvdata/qemuxml2argv-net-virtio-netdev.args: Update
for new simpler naming scheme
The virDomainDeviceInfoIterate() function will provide a
convenient way to iterate over all devices in a domain.
* src/conf/domain_conf.c, src/conf/domain_conf.h,
src/libvirt_private.syms: Add virDomainDeviceInfoIterate()
function.
This reverts commit cdc42d0a48.
As DanB pointed out, this patch is actually wrong. The real
bug that was causing me to see this problem is a bug
introduced in a RHEL-5 libvirt snapshot, and I'm going to
fix the real bug there.

The <console> tag is supposed to result in addition of a single
<serial> device for HVM guests. The 'targetType' attribute was
missing though causing the compatibility code to add a second
<console> device
* src/conf/domain_conf.c: Set targetType for serial device
When libvirtd shuts down, it places a <state/> tag in the XML
state file it writes out for guests with PCI passthrough
devices. For devices that are attached at bootup time, the
state tag is empty. However, at libvirtd startup time, it
ignores anything with a <state/> tag in the XML, effectively
hiding the guest.
This patch remove the check for VIR_DOMAIN_XML_INTERNAL_STATUS
when parsing the XML.
* src/conf/domain_conf.c: remove VIR_DOMAIN_XML_INTERNAL_STATUS
flag check in virDomainHostdevSubsysPciDefParseXML()
