           Summary: 15_create_smallmem_pos.py hangs on latest unstable
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux-2.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: dsteklof@xxxxxxxxxx


Xm-test's 15_create_smallmem_pos.py hangs and xm-test doesn't complete on
latest unstable. The test creates a domain with very low memory to make sure
that situation can be properly handled. The domain is created and then cycles
with:

Out of Memory: Kill process 2 (migration/0) score 0 and children.

The test configures 16MBs and is now using the -xen kernel.

Related, but possibly another issue:

If I create a domain with 8 MBs, I get:

Error: (9, 'Bad file descriptor')

Although... the xend-debug.log has:

ERROR: Initial guest OS requires too much space
(12MB is greater than 8MB limit)
 (0 = Success)
ERROR: Error constructing guest OS

The tools should properly handle the low memory case. 

I hit these problems on an SMP 32bit system running xen-unstable:
