> I'm not sure if this bug should be recorded with Nova or Ubuntu..
Thanks for the report, IMHO this needs to be addressed by Ubuntu or who
ever is providing libvirt packages as these apparmor profiles are not
shipped within the nova project.

Title:
Snapshoting fails in Mitaka
Status in OpenStack Compute (nova):
Invalid
Bug description:
Description
===========
Running Mitaka installed on Ubuntu 14.04 (upgraded from Juno all the way to
Mitaka). The dashboard reports success even though no snapshot is created.
Steps to reproduce
==================
Take snapshot using dashboard or the Openstack client.
Expected result
===============
New snapshot gets created, image registered in Glance.
Actual result
=============
Dashboard reports success right away, the image shows up in the images tab in
Dashboard shortly before changing status to "Deleted" and disappearing.
The following message gets logged in "/var/log/nova/nova-compute.log".

Researching the error message I found
https://bugs.launchpad.net/fuel/+bug/1638269.
After I applied the patch https://review.fuel-
infra.org/#/c/28086/2/debian/apparmor/libvirt-qemu and restarting the
instance, the snapshot is working fine.
I'm not sure if this bug should be recorded with Nova or Ubuntu..
Thank you.
