           Summary: [IPF-VTI] Creating VTI domain will meet "Cannot allocate
                    memory"
           Product: Xen
           Version: unstable
          Platform: IA64
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HVM
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: yongkang.you@xxxxxxxxx


Environment:
------------
Service OS (ia32/ia32e/IA64): RHEL4u3 IA64
Guest OS (ia32/ia32e/IA64): RHEL4u3 IA64 VTI
Change Set: 10937
Hardware: Tiger4
physical memory: 8G
domain0 mem: 1G
Guest mem: 2G
domain0's sched: bvt

Bug detailed description:
--------------------------
With creating and destroying a 2G memory VTI domain a lot of times (should >5
times), I will meet this issue. Control Panel will report "Cannot allocate
memory" and refuse to create VTI domain.

But if I continue to try to recreate VTI domain for several times, finaly the
VTI domain can be created successfully. So strange~


Reproduce steps:
----------------
1. create 2G memory VTI domain 
2. after it is up, destroy it.
3. redo step 1 and step 2 for several times.
4. meet the creating failure issue.
5. if retrying create several times, VTI domain can be up again.
