[Bug 1637620] Re: cannot delete lxd instances in horizon

[Brian Murray]

Hello Kevin, or anyone else affected,

Accepted nova-lxd into xenial-proposed. The package will build now and
be available at https://launchpad.net/ubuntu/+source/nova-
lxd/13.0.0-0ubuntu3.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

advance!

Title:
  cannot delete lxd instances in horizon

Status in OPNFV:
  New
Status in nova-lxd package in Ubuntu:
  Fix Released
Status in nova-lxd source package in Xenial:
  Fix Committed

Bug description:
  [Impact]
  With later LXD 2.0.x point releases, its not possible to delete instances running on a nova-lxd openstack cloud.

  [Test Case]
  Deploy OpenStack Nova LXD cloud
  nova boot instance
  nova delete instance - fails

  [Regression Potential]
  Minimal; later versions of nova-lxd take a different approach to profile management, but the fix simply ensures that the profile is deleted after the container, rather than the other way around.

  [Original Bug Report]
  After deploying Openstack and spinning up lxd instances we are unable to delete those instances

  The following error appears in Horizon and in the nova-compute logs

  Exception during message handling: Failed to communicate with LXD API
  instance-0000005f: Error 400 - Profile is currently in use

  Its possible to delete the lxc container, then delete the profile.
  Then delete from Horizon.
