QEMU commit 3984890 introduced the "pci-hole64-size" property,
to i440FX-pcihost and q35-pcihost with a default setting of 2 GB.
Translate <pcihole64>x<pcihole64/> to:
-global q35-pcihost.pci-hole64-size=x for q35 machines and
-global i440FX-pcihost.pci-hole64-size=x for i440FX-based machines.
Error out on other machine types or if the size was specified
but the pcihost device lacks 'pci-hole64-size' property.

<pcihole64 unit='KiB'>1048576</pcihole64>
</controller>
It can be used to adjust (or disable) the size of the 64-bit
PCI hole. The size attribute is in kilobytes (different unit
can be specified on input), but it gets rounded up to
the nearest GB by QEMU.
Disabling it will be needed for guests that crash with the
64-bit PCI hole (like Windows XP), see:

The ftp protocol is already recognized by qemu/KVM so add this support to
libvirt as well.
The xml should be as following:
<disk type='network' device='cdrom'>
<source protocol='ftp' name='/url/path'>
<host name='host.name' port='21'/>
</source>
</disk>

QEMU/KVM already allows a HTTP URL for the cdrom ISO image so add this support
to libvirt as well.
The xml should be as following:

<source protocol='http' name='/url/path'>
<host name='host.name' port='80'/>

qemu-img is going to switch the default for QCOW2
to QCOW2v3 (compat=1.1)
Extend the probing for qemu-img command line options to check
if -o compat is supported. If the volume definition specifies
the qcow2 format but no compat level and -o compat is supported,
specify -o compat=0.10 to create a QCOW2v2 image.

virsh cpu-stats guest --start 0 --count 3
It outputs right but the return value is 1 rather than 0
echo $?
1
Found by running libvirt-autotest
./run -t libvirt --tests virsh_cpu_stats
If there's no hard_limit set and domain uses VFIO we still must lock
the guest memory (prerequisite from qemu). Hence, we should compute
the amount to be locked from max_balloon.
When cpu hotplug fails without reporting an error, we would fail the
command but update the count of vCPUs anyways.
Commit 761fc48136 fixed the case when CPU
hot-unplug failed silently, but forgot to fix up the value in this case.

Consistently use "is" or "is not" to compare variables to None,
because doing so is preferrable, as per PEP 8
(http://www.python.org/dev/peps/pep-0008/#programming-recommendations):
> Comparisons to singletons like None should always be done with is or
> is not, never the equality operators.
In tests/qemuagenttest.c, the Timeout test should always be
called last. Any additional tests should come before this.

The virDomainOpenGraphics method accepts a UNIX socket FD from
the client app. It must set the label on this FD otherwise QEMU
will be prevented from receiving it with recvmsg.

If user requested multiqueue networking, beside multiple /dev/tap and
/dev/vhost-net openings, we forgot to pass mq=on onto the -device
virtio-net-pci command line. This is advised at:

Re-arrange the code so that the returned bitmap is always initialized to
NULL even on early failures and return an error message as some callers
are already expecting it. Fix up the rest not to shadow the error.
Commit abfff210 changed the order of vshParseArgv() and vshInit() in
order to make fix debugging of parameter parsing. However, vshInit()
did a vshReconnect() even though ctl->name wasn't set according to the
'-c' parameter yet. In order to keep both issues fixed, I've split
the vshInit() into vshInitDebug() and vshInit().
One simple memleak of ctl->name is fixed as a part of this patch,
since it is related to the issue it's fixing.

Previously the error message showed the following:
error: internal error: Invalid or not yet handled value 'auto detect'
for VMX entry 'ide0:0.fileName'
This left the user unsure if it was a CD-ROM or a disk device that they
needed to fix. Now the error shows:
error: internal error: Invalid or not yet handled value 'auto detect'
for VMX entry 'ide0:0.fileName' for device type 'cdrom-raw'
Which should hopefully make it easier to see the issue with the VMX
configuration.
