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

[Paz]

Hi All

We had the same issue, but in our end it was misconfiguration of the key.
Make sure that the key you see in trace log is indeed the key you have in /etc/ceph/ceph.client.cinder.keying, if not try to fix in /etc/libvirt/secrets/<your uuid>, and reload with virsh secret define.
If it configured OK, make sure that it also configured on ceph cluster (ceph auth list).

  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.
