Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.
<interface type='udp'>
<mac address='52:54:00:5c:67:56'/>
<source address='127.0.0.1' port='11112'>
<local address='127.0.0.1' port='22222'/>
</source>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.

This patch adds feature for lxc containers to inherit namespaces.
This is very similar to what lxc-tools or docker provides. Look
for "man lxc-start" and you will find that you can pass command
args as [ --share-[net|ipc|uts] name|pid ]. Or check out docker
networking option in which you can give --net=container:NAME_or_ID
as an option for sharing +namespace.
>From this patch you can add extra libvirt option to share
namespace in following way.
<lxc:namespace>
<lxc:sharenet type='netns' value='red'/>
<lxc:shareipc type='pid' value='12345'/>
<lxc:shareuts type='name' value='container1'/>
</lxc:namespace>
The netns option is specific to sharenet. It can be used to
inherit from existing network namespace.

This controller can be connected only to a port on a
pcie-switch-upstream-port. It provides a single hotpluggable port that
will accept any PCI or PCIe device, as well as any device requiring a
pcie-*-port (the only current example of such a device is the
pcie-switch-upstream-port).
This controller can be connected only to a pcie-root-port or a
pcie-switch-downstream-port (which will be added in a later patch),
which is the reason for the new connect type
VIR_PCI_CONNECT_TYPE_PCIE_PORT. A pcie-switch-upstream-port provides
32 ports (slot=0 to slot=31) on the downstream side, which can only
have pci controllers of model "pcie-switch-downstream-port" plugged
into them, which is the reason for the other new connect type
VIR_PCI_CONNECT_TYPE_PCIE_SWITCH.
This controller can be connected (at domain startup time only - not
hotpluggable) only to a port on the pcie root complex ("pcie-root" in
libvirt config), hence the new connect type
VIR_PCI_CONNECT_TYPE_PCIE_ROOT. It provides a hotpluggable port that
will accept any PCI or PCIe device.
New attributes must be added to the controller <target> subelement for
this - chassis and port are guest-visible option values that will be
set by libvirt with values derived from the controller's index and pci
address information.
There are some configuration options to some types of pci controllers
that are currently automatically derived from other parts of the
controller's configuration. For example, in qemu a pci-bridge
controller has an option that is called "chassis_nr"; up until now
libvirt has always set chassis_nr to the index of the pci-bridge. So
this:
<controller type='pci' model='pci-bridge' index='2'/>
will always result in:
-device pci-bridge,chassis_nr=2,...
on the qemu commandline. In the future we may decide there is a better
way to derive that option, but even in that case we will need for
existing domains to retain the same chassis_nr they were using in the
past - that is something that is visible to the guest so it is part of
the guest ABI and changing it would lead to problems for migrating
guests (or just guests with very picky OSes).
The <target> subelement has been added as a place to put the new
"chassisNr" attribute that will be filled in by libvirt when it
auto-generates the chassisNr; it will be saved in the config, then
reused any time the domain is started:
<controller type='pci' model='pci-bridge' index='2'>
<model type='pci-bridge'/>
<target chassisNr='2'/>
</controller>
The one oddity of all this is that if the controller configuration
is changed (for example to change the index or the pci address
where the controller is plugged in), the items in <target> will
*not* be re-generated, which might lead to conflict. I can't
really see any way around this, but fortunately if there is a
material conflict qemu will let us know and we will pass that on
to the user.
This new subelement is used in PCI controllers: the toplevel
*attribute* "model" of a controller denotes what kind of PCI
controller is being described, e.g. a "dmi-to-pci-bridge",
"pci-bridge", or "pci-root". But in the future there will be different
implementations of some of those types of PCI controllers, which
behave similarly from libvirt's point of view (and so should have the
same model), but use a different device in qemu (and present
themselves as a different piece of hardware in the guest). In an ideal
world we (i.e. "I") would have thought of that back when the pci
controllers were added, and used some sort of type/class/model
notation (where class was used in the way we are now using model, and
model was used for the actual manufacturer's model number of a
particular family of PCI controller), but that opportunity is long
past, so as an alternative, this patch allows selecting a particular
implementation of a pci controller with the "name" attribute of the
<model> subelement, e.g.:
<controller type='pci' model='dmi-to-pci-bridge' index='1'>
<model name='i82801b11-bridge'/>
</controller>
In this case, "dmi-to-pci-bridge" is the kind of controller (one that
has a single PCIe port upstream, and 32 standard PCI ports downstream,
which are not hotpluggable), and the qemu device to be used to
implement this kind of controller is named "i82801b11-bridge".
Implementing the above now will allow us in the future to add a new
kind of dmi-to-pci-bridge that doesn't use qemu's i82801b11-bridge
device, but instead uses something else (which doesn't yet exist, but
qemu people have been discussing it), all without breaking existing
configs.
(note that for the existing "pci-bridge" type of PCI controller, both
the model attribute and <model> name are 'pci-bridge'. This is just a
coincidence, since it turns out that in this case the device name in
qemu really is a generic 'pci-bridge' rather than being the name of
some real-world chip)
"Further" clarification (and testing) shows that using a SCSI Fibre
Channel NPIV device/lun from a storage pool as a <disk type='volume'
device'lun'> will work. So just add that to the allowable options

Also move the mention of version numbers for the various PCI
controller models up to the end of the sentence where they are first
given, to avoid confusion.
When support for the pcie-root and dmi-to-pci-bridge buses on a Q35
machinetype was added, I was concerned that even though qemu at the
time allowed plugging a PCI device into a PCIe port, that it might not
be supported in the future. To prevent painful backtracking in the
possible future where this happened, I disallowed such connections
except in a few specific cases requested by qemu developers (indicated
in the code with the flag VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG).
Now that a couple years have passed, there is a clear message from
qemu that there is no danger in allowing PCI devices to be plugged
into PCIe ports. This patch eliminates
VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG and changes the code to always
allow PCI->PCIe or PCIe->PCI connection *when the PCI address is
specified in the config. (For newly added devices that haven't yet
been given a PCI address, the auto-placement still prefers using the
correct type of bus).
In my previous fix (1310b1358) I've tried to solve an ordering

Defining a domain with a SCSI disk attached via a hostdev

causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest

The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

Since the reference unit and target fields are used in

When generating the path to the dir for a CIFS/Samba driver, the code
would generate a source path for the mount using "%s:%s" while the
mount.cifs expects to see "//%s/%s". So check for the cifsfs and
format the source path appropriately.
Additionally, since there is no means to authenticate, the mount
needs a "-o guest" on the command line in order to anonymously mount
the Samba directory.
Commit id '887dd362' added support for a netfs pool format type 'cifs'
and 'gluster' in order to add rng support for Samba and glusterfs netfs
pools. Originally, the CIFS type support was added as part of commit
id '61fb6979'. Eventually commit id 'b325be12' fixed the gluster rng
definition to match expectations.
As it turns out the CIFS rng needed a similar change since the directory
path is not an absDirPath, rather just a dirPath will be required.

The XML parser sets a default <mode> if none is explicitly passed in.
This is then used at pool/vol creation time, and unconditionally reported

are some cases where we want to make this distinction, but we currently
can't.
Handle <mode> parsing like we handle <owner>/<group>: if no value is

Remove the check for the source host name for iSCSI source XML processing
declaring duplicate sources when the source device path and if present the
initiator of a proposed storage pool matches an existing storage pool.
The backend iSCSI storage driver uses 'iscsiadm --mode session' to query
available iscsid target sessions. The output displayed is the IP address
and the IQN (target path) of known targets. The displayed IP address
is a resolved address based on the session --login. Additionally, iscsid
keeps track of the various ways to define the host name (IPv4 Address,
IPv6 Address, /etc/hosts, etc.) for that IQN (see output of an 'iscsiadm
--mode node'). If an incoming IQN matches and the host name provided by
libvirt is resolved to the existing IQN, then iscsid will "reuse" the
session. Although libvirt could do the same name resolution, if there
is a difference, iscsid could still declare two seemingly different sources
to be the same and not create a new session which means libvirt now has
two storage pools looking at the same source. Thus to avoid any strange
host name resolution issues, just rely on iscsid for that and do not
allow multiple pools on the same host to use the same device path (IQN).

A new feature that can be turned on or off.
The QEMU machine vmport option allows to set the VMWare IO port
emulation. This emulation is useful for absolute pointer input when the
guest has vmware input drivers, and is enabled by default for kvm.
However it is unnecessary for Spice-enabled VM, since the agent already
handles absolute pointer and multi-monitors. Furthermore, it prevents
Spice from switching to relative input since the regular ps/2 pointer
driver is replaced by the vmware driver. It is thus advised to disable
vmport when using a Spice VM. This will permit the Spice client to
switch from absolute to relative pointer, as it may be required for
certain games or applications.
The phyp driver stuffed it into a DomainDefPtr during its attachdevice

Remove the iothreadspin array from cputune and replace with a cpumask

list now.
Adding a new XML element 'iothreadids' in order to allow defining
specific IOThread ID's rather than relying on the algorithm to assign
IOThread ID's starting at 1 and incrementing to iothreads count.
This will allow future patches to be able to add new IOThreads by
a specific iothread_id and of course delete any exisiting IOThread.
Each iothreadids element will have 'n' <iothread> children elements
which will have attribute "id". The "id" will allow for definition
of any "valid" (eg > 0) iothread_id value.
On input, if any <iothreadids> <iothread>'s are provided, they will
be marked so that we only print out what we read in.
On input, if no <iothreadids> are provided, the PostParse code will
self generate a list of ID's starting at 1 and going to the number
of iothreads defined for the domain (just like the current algorithm
numbering scheme). A future patch will rework the existing algorithm
to make use of the iothreadids list.
On output, only print out the <iothreadids> if they were read in.

If this enviroment variable is set, the virTestCompareToFile helper
will overwrite the file content we are comparing against, if the
file doesn't exist or it doesn't match the expected input.
This is useful when adding new test cases, or making changes that
generate a lot of output churn.
The PortNumber data type is declared to derive from 'short'.
Unfortunately this is an signed type, so validates the range
[-32,768, 32,767] which excludes valid port numbers between
32767 and 65535.
We can't use 'unsignedShort', since we need -1 to be a valid
port number too.
This change is to use 'int' and set an explicit max boundary
instead of relying on the data types' built-in max.
One of the existing tests is changed to use a high port number
to validate the schema.

According to docs, using 'lun' as a value for device attribute is only valid
with disk types 'block' and 'network'. However current RNG schema also allows
a combination type='file' device='lun' which results in a successfull
xml validation, but fails at qemuBuildCommandLine.
Besides fixing the RNG schema, this patch also adds a qemuxml2argvtest
for this case.

The <inbound/> element to <bandwidth/> has several attributes from
which two are mandatory. Well, from two at least one has to be
present: @average or @floor or both. Instead of inventing crazy RNG
schema, let's make all the attributes optional there and rely on our
parsing code to correctly handle the situation.

On IRC, Hydrar pointed a problem where 'virsh edit' failed on
his domain created through an ISCSI pool managed by virt-manager,
all because the XML included a block device with colons in the
name.
* docs/schemas/basictypes.rng (absFilePath): Add colon as safe.
* tests/qemuxml2argvdata/qemuxml2argv-disk-iscsi.xml: New file.
* tests/qemuxml2argvdata/qemuxml2argv-disk-iscsi.args: Likewise.
* tests/qemuxml2argvtest.c (mymain): Test it.

When using QEMU's 9pfs the target "dir" element is not necessarily an
absolute path but merely an arbitrary identifier. So validation in that
case currently fails with the misleading
$ virt-xml-validate /tmp/test.xml
Relax-NG validity error : Extra element devices in interleave
/tmp/test.xml:24: element devices: Relax-NG validity error : Element domain failed to validate content
/tmp/test.xml fails to validate
because network address is required by route, so
here we should add one avoid user misunderstand.

The virNodeDeviceDettach API only works on PCI devices.
Originally added by commit 10d3272e, but the API never
supported USB devices.

Commit bab2eda changed the behavior for missing compat attribute,
but failed to update the documentation.
Before, the option was omitted from qemu-img command line and the
qemu-img default was used. Now we always specify the compat value
and the default is 0.10.

This patch adds code that parses and formats configuration for memory
devices.
A simple configuration would be:
<memory model='dimm'>
<target>
<size unit='KiB'>524287</size>
<node>0</node>
</target>
</memory>
A complete configuration of a memory device:
<memory model='dimm'>
<source>
<pagesize unit='KiB'>4096</pagesize>
<nodemask>1-3</nodemask>
</source>
<target>
<size unit='KiB'>524287</size>
<node>1</node>
</target>
</memory>
This patch preemptively forbids use of the <memory> device in individual
drivers so the users are warned right away that the device is not
supported.
