The only one that works for me is xbd1d:

# zpool create tank /dev/rxbd1
cannot open '/dev/rxbd1': No such file or directory
# zpool create tank rxbd1
cannot open 'rxbd1': no such GEOM provider
must be a full path or shorthand device name
# zpool create tank rxbd1d
cannot create 'tank': invalid argument for this pool operation
# zpool create tank xbd1
cannot open 'xbd1': no such GEOM provider
must be a full path or shorthand device name
# zpool create tank /dev/xbd1
cannot open '/dev/xbd1': No such file or directory
# zpool create tank xbd1d
# zpool export tank
# zpool import tank
cannot import 'tank': no such pool available
