+++ This bug was initially created as a clone of Bug #909286 +++ Because nova-manage imports rpc, it will be default try to import kombu as this is the default upstream. A quick fix would be to set qpid as the default, though there may be other significant configs in nova-dist.conf (in future) so the most general solution would be to get nova-* commands to use nova-dist.conf too. It's a pity /etc/nova/nova.conf can't just include nova-dist.conf
The fix for this will be much the same as the corresponding one for nova https://bugzilla.redhat.com/attachment.cgi?id=695652
Release notes for snapshot2: If not using packstack, to work around this issue please uncomment the rpc_backend and sql_connection settings in /etc/nova/nova.conf after the packages are installed
