Is there a better strategy? Could one mount /export/home directly (i.e.

It really comes down to what problem your
trying to solve...
You could use NFS as Tommy suggests... If your
trying to get the best perf or not impact you
NIC perf, you can use a block device as your doing.
Some useful questions...
Can you carve up your LUNs on the SAN?
Can you snapshot/rollback your LUNs?
If not, you probably want to use zfs/zvols on dom0.
Do you want to be able to snapshot and rollback
/export/home on the guest... i.e. I would imagine
you would want to backup at the SAN or dom0.. But
do you also want to be able to do this on the guest.
(i.e. you don't have to use zfs for /export/home on
the guest).
If you can carve up and snapshot your LUNs, you can
just pass through the disk to domU. i.e. ideally, you
want to manage are the SAN source, then pass through the
SAN disks right to the guest..
And of course, you need to think about migration, etc..
