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

I'm running Ubuntu 14.04.3 with cloud and ceph repositories.

ceph 0.94.3-1trusty

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.
