I use SLES10 SP2 for my dom0, which has a few tools that make this possible:
- EVMS + Heartbeat for shared block devices
- OCFS2 for a clustered filesystem
- Heartbeat for maintaining availability.
I have a volume shared out from my SAN that's managed with EVMS on each of my Xen servers. I created an OCFS2 filesystem on this volume and have it mounted on all of them. This way I do file-based disks for all of my domUs and they are all visible to each of my hosts. I can migrate the domUs from host to host. I'm in the process of getting Heartbeat setup to manage my domUs - Heartbeat can be configured to migrate VMs or restart them if one of the hosts fails.
It isn't a "single-click" solution - it takes a little work to get everything running, but it does work.

Anyone aware of any clustering package for xen, in order to gain redundancy, etc.
