Subject Error Creating VMs and viewing hosts
Date Mon, 15 Oct 2012 14:50:44 GMT
I migrated some VMs around to different storage tags (I have two primary 
SANs, HD and SSD), and at some point, a migration failed, with this error:

Now, I can't view my hosts under Infrastructure, and can't create new 
VMs.  I don't have any local storage in my cloud, so I don't understand 
the reference to local storage in the log. When I go to view hosts I get 
an empty popup box.  All my storage and hosts are online, so my guess 
this is a database error, but I don;t know where to look.
