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
routine, but the value is never advertised via capabilities so it should
be safe to drop.
Have the phyp driver use OSTYPE_LINUX, which is what it advertises via
capabilities.
With iothreadid's allowing any 'id' value for an iothread_id, the
iothreadsched code needs a slight adjustment to allow for "any"
unsigned int value in order to create the bitmap of ids that will
have scheduler adjustments. Adjusted the doc description as well.
Remove the iothreadspin array from cputune and replace with a cpumask
to be stored in the iothreadids list.
Adjust the test output because our printing goes in order of the iothreadids
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.
In a lot places we use path like this:
$(srcdir)/../src/....
when in fact it can be:
$(top_srcdir)/src/

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

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.

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.
To enable memory hotplug the maximum memory size and slot count need to
be specified. As qemu supports now other units than mebibytes when
specifying memory, use the new interface in this case.
Add a XML element that will allow to specify maximum supportable memory
and the count of memory slots to use with memory hotplug.
To avoid possible confusion and misuse of the new element this patch
also explicitly forbids the use of the maxMemory setting in individual
drivers's post parse callbacks. This limitation will be lifted when the
support is implemented.

I spent quite some time figuring that backingStore info
isn't included in the dom xml, unless guest is up and
running. Hopefully putting that in the doc should help.
Also, several people have complained that libvirt reports
a backing file as raw, even though they expected it to be
qcow2; where the culprit is usually the user forgetting to
create the file with qemu-img create -o backing_fmt=qcow2.
This patch adds that info to the doc.

Midonet is an opensource virtual networking that over lays the IP
network between hypervisors. Currently, such networks can be made
with the openvswitch virtualport type.
This patch, defines the schema and documentation that will serve
as basis for the follow up patches that will add support to libvirt
for using Midonet virtual ports for its interfaces. The schema
definition requires that the port profile expresses its interfaceid
as part of the port profile. For that reason, this is part of the
patch too.

We're parsing memballoon status period as unsigned int, but when we're
trying to set it, both we and qemu use signed int. That means large
values will get wrapped around to negative one resulting in error.
Basically the same problem as commit e3a7b874 was dealing with when
updating live domain.
QEMU changed the accepted value to int64 in commit 1f9296b5, but even
values as INT_MAX don't make sense since the value passed means seconds.
Hence adding capability flag for this change isn't worth it.

Now that the size of guest's memory can be inferred from the NUMA
configuration (if present) make it optional to specify <memory>
explicitly.
To make sure that memory is specified add a check that some form of
memory size was specified. One side effect of this change is that it is
no longer possible to specify 0KiB as memory size for the VM, but I
don't think it would be any useful to do so. (I can imagine embedded
systems without memory, just registers, but that's far from what libvirt
is usually doing).
Forbidding 0 memory for guests also fixes a few corner cases where 0 was
not interpreted correctly and caused failures. (Arguments for numad when
using automatic placement, size of the balloon). This fixes problems
described in https://bugzilla.redhat.com/show_bug.cgi?id=1161461
Test case changes are added to verify that the schema change and code
behave correctly.
The version attribute in redirdev filters refers to the revision
of the device, not the version of the USB protocol.
Explicitly state that this is not the USB protocol and remove references
to those round version numbers that resemble USB protocol versions.

Our code supports that for ages. When using a <filterref/> to an

There was a mess in the way how we store unlimited value for memory
limits and how we handled values provided by user. Internally there
were two possible ways how to store unlimited value: as 0 value or as
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED. Because we chose to store memory
limits as unsigned long long, we cannot use -1 to represent unlimited.
It's much easier for us to say that everything greater than
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED means unlimited and leave 0 as valid
value despite that it makes no sense to set limit to 0.
Remove unnecessary function virCompareLimitUlong. The update of test
is to prevent the 0 to be miss-used as unlimited in future.

According to the formatstorage.html description for <source> element
and "format" attribute: "All drivers are required to have a default
value for this, so it is optional."
As it turns out the disk backend did not choose a default value, so I
added a default of "msdos" if the source type is "unknown" as well as
updating the storage.html backend disk volume driver documentation to
indicate the default format is dos.
Our documentation isn't 100% clear about hostdev 'managed' attribute usage,
because it only makes sense to use it with PCI devices, yet we format
this attribute to all hostdev devices. By adding a note into the docs,
we can possibly avoid confusion from customer's side and also avoid a solution
using ternary logic.

The element wasn't declared under the interleave thus it was required
always to be first. This made it inconvenient when pasting new stuff to
the XML manually in the "wrong" place.
The "virtio-mmio" is perfectly valid address type which we parse and

At least Xen supports backend drivers in another domain (aka "driver
