Hi Kirk, I've seen this behaviour with KVM (I filed bug CloudStack-3535) but we've found XenServer works fine.
There is a global setting (alert.wait) which is blank by default. This is the number of seconds CloudStack waits after it loses communication a host before doing anything. Blank somehow equals 30 mins in this case.
