[Bug 1432644] Re: VM permanently tries to read /dev/shm/lttng-ust-wait-5

[Matt Fischer]

We're using libvirt 1.2.12-0ubuntu13~cloud0.

Patz: There is noting in syslog about a key. I don't believe this bug
has anything to do with a key.

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.
