** Description changed:

+ ====================================================
+ 1. Impact: cannot start vms inside a container
+ 2. Devel solution: drop the cgmanager patches
+ 3. Stable solution: same as devel solution
+ 4. Test case: see comment #7 below for a very detailed and easy to use example
+ 5. Regression potential: There should be no regressions, and the 
lp:qa-regression-tests passed.
+ ====================================================
+ 
  Our installer attempts to load VM's within an lxc container. This worked
  on trusty, however, with the latest releases from vivid and wily those
  VM's are unable to start. This affects running juju-local within a
  container as well.
  
  We think it has something to do with cgmanager/cgproxy, however, we can
  manually run and launch qemu just fine within the container. This could
  potentially be an issue with libvirt attempt to set cgroup values for
  the qemu processes.
  
  The current workaround to get a VM to start within a vivid and wily
  container running LXC 1.1.2+ is to disable cgroups in
  /etc/libvirt/qemu.conf
  
  I'm starting this bug and will ask Ryan Harper to provide a more in-
  depth result of his debugging, but, wanted to have this on the radar.
