[libvirt] [PATCH] qemu: fix crash in migrate when migrateuri do not have a scheme
by Luyao Huang
https://bugzilla.redhat.com/show_bug.cgi?id=1191355
When we migrate a vm with migrateuri option with a uri do not
have scheme like this:
# virsh migrate test4 --live qemu+ssh://lhuang/system --migrateuri 127.0.0.1
target libvirtd will crashed because uri->scheme is NULL in
qemuMigrationPrepareDirect this line:
if (STRNEQ(uri->scheme, "tcp") &&
add a value check before this line.

[libvirt] [PATCH] virsh: fix show the wrong IP address for network type listen address graphic
by Luyao Huang
https://bugzilla.redhat.com/show_bug.cgi?id=1191016
We try to get the IP address in /domain/devices/graphics/@listen, howerver
for the network type listen address donnot have this parameter, it will
show the address in the /domain/devices/graphics/listen/@address, running
XML like this:
<graphics type='spice' port='5901' autoport='yes' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
This patch will try to get the IP address in this path
/domain/devices/graphics/listen/@address

[libvirt] [PATCH v2] qemu: fix setting of VM CPU affinity with TCG
by Daniel P. Berrange
If a previous commit I fixed the incorrect handling of vcpu pids
for TCG mode QEMU:
commit b07f3d821dfb11a118ee75ea275fd6ab737d9500
Author: Daniel P. Berrange <berrange(a)redhat.com>
Date: Thu Dec 18 16:34:39 2014 +0000
Don't setup fake CPU pids for old QEMU
The code assumes that def->vcpus == nvcpupids, so when we setup
fake CPU pids for old QEMU with nvcpupids == 1, we cause the
later code to read off the end of the array. This has fun results
like sche_setaffinity(0, ...) which changes libvirtd's own CPU
affinity, or even better sched_setaffinity($RANDOM, ...) which
changes the affinity of a random OS process.
The intent was that this would merely disable the ability to set
per-vCPU affinity. It should still have been possible to set VM
level host CPU affinity.
Unfortunately, when you set <vcpu cpuset='0-1'>4</vcpu>, the XML
parser will internally take this & initialize an entry in the
def->cputune.vcpupin array for every VCPU. IOW this is implicitly
being treated as
<cputune>
<vcpupin cpuset='0-1' vcpu='0'/>
<vcpupin cpuset='0-1' vcpu='1'/>
<vcpupin cpuset='0-1' vcpu='2'/>
<vcpupin cpuset='0-1' vcpu='3'/>
</cputune>
Even more fun, the faked cputune elements are hidden from view when
querying the live XML, because their cpuset mask is the same as the
VM default cpumask.
The upshot was that it was impossible to set VM level CPU affinity.
To fix this we must update qemuProcessSetVcpuAffinities so that it
only reports a fatal error if the per-VCPU cpu mask is different
from the VM level cpu mask.

[libvirt] virsh vcpuinfo with tcg
by Serge Hallyn
Hi,
'virsh vcpuinfo' in 1.2.12 returns an empty line for VMs using tcg. I
assume this is due to commit b07f3d821dfb11 which explicitly sets
nvcpupids to 0 now. Is 'virsh vcpuinfo' returning nothing just an
unfortunate but expected side-effect, or is it a bug and it should
return info anyway? My impression is that qemu_driver.c should be
using vm->def->vcpus rather than priv->nvcpupids to determine the
# of cpus to show?
thanks,
