           Summary: Hypervisor panic on xm restore
           Product: Xen
           Version: 3.0.1
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: greenrd@xxxxxxxxxxx


The hypervisor panics with the message below when I try to use xm restore on a
saved image of a domain that I created last night with xm save. I think the only
thing that's changed on dom0 is its IP address and domain name.
