Also, if block-reconfigure would work, it would also be nice

1. make a live copy of the partition file but bigger
2. pause the domU
3. mount both in dom0
4. do a last rsync
5. umount again
6. block-reconfigure to the new one
7. unpause the domU 

but i'd prefer growing on dom0 and propagating the change...
