snapshot and replication works fine on the host, acting on the zvol.

what kind of zpool do you use in the guest, to avoid unwanted additional
redundancy?
did you benchmark the space or time efficiency of ZFS vs. UFS?
in some bsd related meeting this year i asked allan jude for a bhyve
level null mount, so that we could access at / inside the guest some
subtree of the host, and avoid block devices and file systems
altogether. right now i have to use nfs for that, which is irritating.
