The hosting dom0 fails immediately with: [2011-07-25 13:49:01 9265] INFO (XendDomainInfo:2078) Domain has shutdown: name=migrating-nathanxenuk2 id=1 reason=suspend.

The same vm and dom0's work fine as soon as I decrease the ram below the 32gb mark. Anyone have any insight on what might be going on here?
