Since you don't tell us what error you get from the guest setup program,
I can only guess that you are using a ZFS volume with a block size of 8k
(default).
My next guess is that you use BHYVE_UEFI.fd for bootrom.
The latter can't boot from 8k drives,
Make sure you define something like this:
-s 3,virtio-blk,/dev/zvol/hostPool/bhyveVOL/sys/guest1,sectorsize=512/4096

If that power guess didn't hit, you need to provide some details (boot
method at very first along with some kind of error description).
