If you want to share a vm between 2 hosts and migrate the vm without
stopping it you ned to use a cluster file system. On SuSE we normally
use OCFS2, on redhat I believe it's gfs. One of the issues we've
encountered with OICFS2 is that it doesn't do sparce files. My firm
has been experimenting with using Veritas cluster file system with XEN
on SLES 10.1. We arfe going at it slowly since it's not a supported as
a configuration by either Novell or Symantec at the moment.
