           Summary: Destination host of migration crashes
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: dbarrera@xxxxxxxxxx
                CC: hohnbaum@xxxxxxxxxx


I am testing the migration feature. When I attempted to migrate to a host, the
host to which I am migrating the domain crashed. It looks like the receiving
host is running out of memory; however, dom0 should not crash.
