I've done this with md mirroring instead of lvm but I haven't gotten to 
the live migration part.  You create and manage the md on dom0 and give 
that to the domU via phy: mappings.
The way I see it, you'd have to break the mirror during migration (or 
keep it broken on the inactive dom0) and then re-sync it on the 
new-active node during migration.  But yeah, given clvm on iSCSI and 
some fancy migration scripting, I don't see why this wouldn't work.
