Maybe, btw I had another issue with linux guests and vmware server
2.0: after moving them to another node, vmware required to register
them again.
I had to play here with .vmx options and moving some /etc/vmware files
to clustered gfs  to avoid this. And vmware server 1.0.x seems more
stable here.

For relocating the guests to another cluster node I did a custom
script that first tries to suspend the guests, if it fails, it powers
off them, then stops the vmware daemons, and everything is ready for a
new node vmware server to start with the same guests.

Diego.
