Subject Get system VM out of hung migrating state
Date Thu, 17 Jan 2013 05:08:41 GMT
Ok, the saga of the hung console proxy VM continues, and I really need 
to get this cleaned up.  After a hard reboot and having to force the 
hypervisor online via the database, my consol proxy VM is still hung in 
migrating state, so CS essentially ignores it:

}

How do I get this VM back online, and do any developers need anything to 
try and dtermine what is wrong?  The status of system VMs and hosts is 
VERY fragile in CS, and there seems to be little error recovery in 
place.  CS shoudl not just ignore a VM in a migrating state.  I have a 
migratewait setting of 3600 seconds, but this VM has been in this state 
 > 24 hours, after multiple management restarts.
