I have this on a DOMU:

# zpool status
  pool: extratank
 state: ONLINE
  scan: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        extratank   ONLINE       0     0     0
          xbd3a     ONLINE       0     0     0
          xbd2a     ONLINE       0     0     0
          xbd4a     ONLINE       0     0     0


These are just normal xbdN presented devices with a simple disklabel
starting at 0.  I don't remember why I ended up doing this way.
