You can do either -- that is, you can mount GFS on domain-0 nodes
(physical nodes) and use GFS to host file system images for the guest
machines.

Alternatively, you could also provide GFS to domain-Us
(unprivileged/guest Xen domains).  Rob Kenna wrote a Red Hat Magazine
article about how to do the former, and I've done the latter.

I'm not sure how many people have tried both simultaneously - that is, I
don't know if GFS on the dom0 machines has been used to host a GFS image
on the domU machines; when I did shared-images between domUs, it was on
ext3 on a single machine (dom0s were not clustered).

Maybe others could comment about their experiences.
