[Bug 1434999] [NEW] Creating a new VM in virt-manager fails because of apparmor permissions

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

When creating a new VM, it fails because of insufficient permissions.
Adding permissions for /dev/shm/lttng-ust-wait-5 and
/var/lib/libvirt/qemu/channel/target to /etc/apparmor.d/abstractions
/libvirt-qemu seems to solve it, although there are still DENIED
messages in the logs:

[  +0,208881] audit: type=1400 audit(1427028845.637:313): apparmor="DENIED" operation="open" profile="/usr/lib/libvirt/virt-aa-helper" name="/dev/shm/lttng-ust-wait-5" pid=9562 comm="virt-aa-helper" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
[  +0,000045] audit: type=1400 audit(1427028845.637:314): apparmor="DENIED" operation="open" profile="/usr/lib/libvirt/virt-aa-helper" name="/dev/shm/lttng-ust-wait-5" pid=9562 comm="virt-aa-helper" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

I know literally nothing about apparmor, but I hope someone who does can
look into this and fix it properly before release of 15.04. Please
contact me if any more information is needed, I will be happy to help as
much as I can.
