           Summary: Unable to access restored domain
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: dbarrera@xxxxxxxxxx

After saving an active domain, I attempted to restore it. 'xm list' shows the
domain as active; however, I am unable to access it either via the console or
ssh. The interesting thing is I can ping the 'restored' domain. 

Seeing this on a non PAE SLES 9 box, and a PAE enabled FC4 box.

this is on a SLES 9, non PAE box:

Notice how 'xm list' shows vm1 twice.
