So what you suggest is that I use DRDB to mirror those nbd devices
between the to app servers ? Or how would yot do it ?

I don't think Novell or RH are making recommendations fo Xen clustering yet.

For physical machines IIRC:
RH supports nbd/md to mirror drives between 2 computers on their enterprise products.

SLES supports drbd which does the whole job.

I've not heard of trying to mix nbd with drbd, but if you are implying you have 3 computers (or VMs), a nbd server and 2 clients, it may be the way to go.

Would you be running the nbd server on dom0 and the clients on domU?
