--- Comment #1 from James Blachly <james.blachly@gmail.com> ---
On the illumos side, Hans Rosenfeld reports that the actual issue is that f=
or
file-backed virtio-block devices, bhyve reports the block size is equal to =
the
recordsize of the underlying ZFS system, i.e. 128k in my case. This is larg=
er
than ASHIFT_MAX thus pool creation fails.

The :lba-access-ok flag is then unrelated but still of note.
