Code review comment for lp:~zulcss/openstack-charm-testing/lxd-qa

I would suggest a 3rd set of bundles:

bundles/lxd/isolate/next.yaml
bundles/lxd/isolate/stable.yaml

Which are identical to bundles/lxd/next.yaml and bundles/lxd/stable.yaml, except that the lxd service deploys from source or trunk or wherever tip is.

ie. Deploy everything from distro/cloud archive, except for lxd.

IMHO, That is where you will best detect whether lxd changes have broken something badly.
