        Is this posible? Does anybody use this idea (or similar)? Could anybody
point me to some documentation?

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.
