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

[Seth Arnold]

Ken, that's great: denying lttng in the profile just to silence the logs
is certainly unfortunate for the people who want to use lttng to measure
and inspect their VMs as the reason why lttng doesn't work is impossible
to discover.

Thanks

  VM permanently tries to read /dev/shm/lttng-ust-wait-5

  Confirmed

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.
