[libvirt] [PATCH] Fix build without polkit
by Pavel Hrdina
The commit 1b854c76 introduced a new function 'virPolkitCheckAuth' and
in the #else section when you don't have polkit all attributes should be
follwed by ATTRIBUTE_UNUSED.

[libvirt] [PATCH 0/4] Add API to manipulate huge pages pool
by Michal Privoznik
This may seem like a cherry on top of the cake, but once we allow
guests to use huge pages we must allow admins to allocate ones.
Michal Privoznik (4):
Introduce virNodeAllocPages
virnuma: Introduce virNumaSetPagePoolSize
nodeinfo: Implement nodeAllocPages
virsh: Expose virNodeAllocPages

[libvirt] [PATCH] tunable_event: extend debug message and tweak limit for remote message
by Pavel Hrdina
It would be nice to also print a params pointer and number of params in
the debug message and the previous limit for number of params in the rpc
message was too large. The 2048 params will be enough for future events.

[libvirt] [RFC] exclusive vcpu-cpu pinning
by Ján Tomko
Hello developers!
Currently, our default cgroup layout is:
-top level cgroup
\-machine (machine.slice with systemd)
`-vm1.libvirt-qemu (machine-qemu\x2dvm1.scope with systemd)
`-emulator
`-vcpu0
\-vcpu1
\-vm2.libvirt-qemu
`-emulator
`-vcpu0
`-vcpu1
To free some CPUs for exclusive use, either all processes from the top level
cgroup should be moved to another one (which does not seem like a great idea)
or isolcpus= should be specified on the kernel command line.
The cpuset.cpu_exclusive option can be set on a cgroup if
* all the groups up to the top level group have it set
* the cpuset of the current group is a subset of the parent group
and no siblings use any cpus from the current cpuset
This would mean that to keep the existing nested structure, all vcpus and the
emulator thread would need to have an exclusive CPU, e.g:
<vcpu placement='static' cpuset='4-6'>2</vcpu>
<cputune exclusive='yes'>
<vcpupin vcpu='0' cpuset='5'/>
<vcpupin vcpu='1' cpuset='6'/>
<emulatorpin cpuset='4'/>
</cputune>
(The only two issues I found:
1) libvirt would have to mess with systemd's 'machine-scope' behind it's back
(setting cpu_exclusive)
2) creating machines without explicit cpu pinning fails, as libvirt tries to
write all the cpus to the cpuset, even those the other machine uses
exclusively)
I've also thought about just keeping track of the 'exclusived' CPUs in
libvirt. This would not work across drivers. And it could possibly be needed
to solve issue 2).
Do you think any of these options would be useful?

[libvirt] [PATCH] hotplug: Fix libvirtd crash on qemu-attached guest
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1141621
Using qemu-attach to attach to a qemu created process and then
attempting to virsh detach-interface caused a libvirtd crash
since the assumption was that device aliases were in place and
that assumption is not necessarily true for the qemu-attach environment.
Add some more verbiage to the virsh man page.
Signed-off-by: John Ferlan <jferlan(a)redhat.com>
---
Notes:
* The bz also mentions a failure for the hotplug/virsh attach-interface,
but that has been resolved by commit id 'ba7468db'
* For the bz, the attempt to attach-interface/hotplug still is not
successful, since device aliases are not set for the PCI controller.
* I did try adding a call to qemuAssignDeviceAliases() during the qemu-
attach code; however, that failed as well (perhaps for a different
reason) as the attach to PCI slot 3 function 0 was not available
for rtl8139 since it was being used by e1000
* If it's desired to add the alias call in that's fine, then that could
be added in qemuDomainQemuAttach prior to the qemuDomainAssignAddresses
call similar to qemuConnectDomainXMLToNative.

[libvirt] bad rpm: libvirt-daemon-1.2.8-1

Since libvirt-daemon-1.2.8-5 fixes the problem, I just wanted to give
everyone a heads up. The libvirt-daemon-1.2.8-1 has an error in the
spec file scripts which causes removal failure.
I had to manually rpm -e --noscripts libvirt-daemon-1.2.8-1.fc20.x86_64
and then I reinstalled libvirt-daemon-1.2.8-5 to make sure things were
"clean".
The error was:
