Xen users - May 2006 - RE: correction... cannot create 2GB (not 2MB) domU

On Unisys 16X 16GB ES7000/one with SLES10 Beta11 updated to xen changeset 9998,
attempted to create a 2GB domU and get Error: The privileged domain did not
balloon. xm list shows that before the attempt to create the domain, dom0 has
15910 MB memory.  After the error, dom0 has dropped down to 13993 MB.

Bugzilla number is 650
