Bug is open with Canonical: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1432644/
Logs are constantly spammed with:

VM permanently tries to read /dev/shm/lttng-ust-wait-5
When used with enforced apparmor profile, this results in logs filled with denied messages.
As I understand it, liblttng is here to allow tracing / debugging in python (not sure). Maybe virt-manager shouldn't be shipped with debugging mode enabled by default, or maybe it is a perfectly legitimate feature and the apparmor profile should be updated.
lttng is disabled in Infernalis by default, but need to address issue being seen in Hammer.

This is already fixed in the hammer branch by 5d204db..a81bcf7
This series turns off lttng by default, and lets it be enabled via conf settings as needed.
