           Summary: xm save --checkpoint makes HVM guest window disappear
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: tfraser@xxxxxxxxxx


Observed behavior:
------------------
Upon making a checkpoint with "xm save --checkpoint", the checkpointed
HVM guest window disappears.


Expected behavior:
------------------
Expected the checkpointed HVM guest's window to remain visible and
the checkpointed HVM guest to continue running normally.


To reproduce:
-------------
(1) Create an HVM guest.
(2) Run "xm save --checkpoint <id> mycheckpointfile"

Note that "xm restore" works on the saved state file.
