[ovirt-users] How to force removal of old host from Engine

Hi, I seem to have got a stale host in my engine that I can't remove. I recently reinstalled oVirt Node on this host and while trying to refresh the host in the engine, have got it in some state where I can't do anything. The host is listed as Status=Unassigned. Under the Management pull down I only have Restart and Stop options, both of which error if selected. The Remove button is not available. How do I force a removal of this host from the view so I can reload it? Shareef.
