I'm affected too by the "log flooding" issue, although I can start VMs.

Bug description:
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.
