[libvirt] [PATCH v2 0/2] Introduce max_anonymous_clients
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=981729
So far we can limit how many clients are connected,
how many are waiting in accept() line but we could
not control the count of accepted but not
authenticated yet.

[libvirt] [PATCH v2 0/5] AppArmor support for lxc containers
by Cédric Bosdonnat
This is a repost of the previous patch series, with the following changes:
* Dropped the patch setting "none" security driver as default in lxc.conf
* Add a patch to implement support for "none" type with apparmor security model.
Cédric Bosdonnat (5):
LXC driver: generate apparmor profiles for guests
Make sure apparmor is started before libvirtd
apparmor: add debug traces when changing profile.
add support for apparmor in lxc-enter-namespace
apparmor: handle "none" type

[libvirt] [PATCH] qemu: monitor: Fix error message and comment when getting cpu info
by Peter Krempa
In qemuMonitorJSONExtractCPUInfo an error message hinted on missing
character device data which is wrong.
Also a comment states that only qemu-kvm tree includes the thread_id
field. This is no longer true.

[libvirt] [PATCH] qemu: snapshot: Use better check when reverting external snapshots
by Peter Krempa
https://bugzilla.redhat.com/show_bug.cgi?id=1071264
Reverting of external snapshots is not supported currently. The check
that is present doesn't properly check for all aspects that make a
snapshot external. Use virDomainSnapshotIsExternal() to do the check.

[libvirt] [PATCH] qemuBuildNicDevStr: Adapt to new advisory on multiqueue
by Michal Privoznik
As I did previously in 4f588a1b46, libvirt needs to set virtio vectors.
Previously, we were advised to use vectors=N, where
N = 2 * (number of queues) + 1
However, just recently this advisory has changed on the Multiquue wiki
page [1] to:
N = 2 * (number of queues) + 2
1: http://www.linux-kvm.org/page/Multiqueue#Enable_MQ_feature
Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com>
---
Notes:
I've had some discussion with qemu developers that qemu is the
best place to compute sane default [1]. And they agreed with me.
However, until they will do so, libvirt should pass the correct
value to make the whole feature work correctly.

* systemd running
