does "cache=off" means disk cache? if so, it might be useful to test
clustering filesystems.

so far, the only way is to setup a network block device (iSCSI, AoE,
nbd). i'd like to simply specify the same backing file for two
instances' hdb parameter.

and snapshots help a lot to go back after blowing up the on-disk structures
