With a zfs root, you need to attach the disk to another

should be ready to boot as a PV guest at this point.
zfs encodes the bootpath in the zpool meta data. When
you import a pool, it updates the meta data.
thanks mark,
so you're saying i need an existing non-zfs-root paravirtualised guest
to start?
yes... There may be a a way getting around the zfs limitation
of having two pools named rpool.. Not sure... For me, it easier to
use a guest without a zfs root.
the question i have is: how to actually move the zfs pool from the
original into a volume on the xvm host? afaik i can't do a zfs send from
a filesystem to a volume:
# zfs send -R rp...@today \
| ssh xvm-host zfs recv -u storage/guests/newvm/disk1
... or can i ?
It would be easier to do a dd :-) But it should be possible
with some extra work to zfs send/recv.. I'll have to give that one
a try.
