           Summary: guest OS cannot be restored after saving.
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: haicheng.li@xxxxxxxxx


Environment:
------------
Service OS (ia32/ia32e/IA64): ia32e,ia32
Guest OS (ia32/ia32e/IA64): ia32e,ia32
Change Set: xen 3.3.0 rc1 #Cset 18145
Hardware: broadwater



Bug detailed description:
--------------------------
I cannot see the window of guest OS after I restored it or migrated it to
localhost.I tried it on ia32e and ia32p but I got the same result.
"xm li" after restoring:

Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   446     2     r-----    680.6
VHREL5-ia32e                                38   256     1     ------      0.0


Reproduce steps:
----------------
1) install xen 3.3.0 rc1 #Cset 18145
2) reboot Dom0 and create guest OS with both ia32e and ia32
3) save the state of guest OS and restore it with save file 

Current result:
----------------
guest OS cannot be restored and I can't connect to guest OS after I migrate it
to localhost.

Expected result:
----------------
I can see the window of guest OS after it is restored and migrated to
localhost.
