With a few minor patches, you could compile the necessary modules inside the the xenU kernel, and enable GFS support for Xen VMs. Unfortunately, the kernels in that Fedora development tree have had symbol problems (missing symbols), so one could not achieve full functionality of a GFS file system (locking wouldn't come up). But, you could create GFS file systems. At present, Xen supplied Fedora kernels (xen0) fail to boot on my test machine (dual Xeon blade), so I can't say if newly compiled kernels load symbols correctly or not. Also, GFS RPMS disappeared from the most recent Fedora development drop, meaning, you would have to find GFS and other stuff in SRPMS form somewhere else and build yourself. Just an FYI... -- Bojan
