This doesn't appear to be a nova issue, the keystone error in c#2
suggesting an issue with memcached in your environment that in turn is
bubbling back up to Glance and finally Nova.

Liberty is also an unsupported release at present so I'm marking this as
invalid for now but feel free to change this if you are able to
reproduce this against a supported release.

** Changed in: nova
       Status: New => Invalid
