I'm running Xen 3.0.2 using the 2.6.16 kernel on Ubuntu Dapper
(the upcoming release). Using a shared ocfs2 volume in multiple
domU's seem to work fine, although I have not extensively tested
(performance?) it yet.

Xen normally refuses to start a domU with a volume that is already
in use (mounted) elsewhere, but you can force it with an exclamation
point. Example:
 disk = ['phy:/dev/vg1/jetU,hda1,w', 'phy:/dev/vg1/shared,hdb1,w!']
                                                              ^^^^^

One last thing, I did compile Xen Xen/Linux from source; I don't
know if the binary distribution includes ocfs2 support.

Regards, Peter
