[Openstack-stable-maint] Nova regression in 2012.2.1

Hey FYI for anyone who hasn't seen it already: http://wiki.openstack.org/ReleaseNotes/2012.2.1 The default of the rpc_control_exchange option for Nova in this release is 'openstack' rather than 'nova' - you need to explicitly set it to 'nova'. See https://bugs.launchpad.net/nova/+bug/1083944 In the project meeting just now Thierry and I discussed doing another quick point release with just this fix and any pending security issue there might be. A snap 2012.2.2 this week might be possible. Depending on how soon we decide to do it, I may block other Nova fixes from stable/folsom in the meantime. Cheers, Mark.
