hostname change on hardware nodes


Hi all,
I'm trying to recover from a mass renaming of our hardware nodes and have
been having a bit of trouble.

After changing the hostname on all of them "nova-manage service list" show
all the old hostname (in the dead state) and all the new host names.  My
first question is how do I remove old services from this list. (eg, if the
hardware dies) and I just want to remove it from the list completely.

My second question is what else do I need to change to get the hostname
change to work correctly.  Right now I believe most operations on instances
are broken because the "host" entry on the table points to the old host
instead of the new one, so deleting a host will hang, etc.
