--- Comment #2 from Martin Birgmeier <d8zNeCFG at aon.at> ---
The boot succeeds if a slice is created for holding the partitions; this is
done by splitting the initial 256 sectors as follows:

[0]# gpart show
=>       1  83886079  vtbd0  MBR  (40G)
         1        15         - free -  (7.5K)
        16  83886064      4  freebsd  [active]  (40G)

=>       0  83886064  vtbd0s4  BSD  (40G)
         0       240           - free -  (120K)
       240   4194304        1  freebsd-ufs  (2.0G)
   4194544   4194304        2  freebsd-swap  (2.0G)
   8388848  75497216        4  freebsd-zfs  (36G)

[0]# bsdlabel vtbd0s4
# /dev/vtbd0s4:

(This is from inside the running VM, therefore showing up as vtbd0 instead of
da0.)

So it seems that in FreeBSD 12.2 bhyveload cannot successfully load a purely
partitioned disk anymore (as opposed to sliced + partitioned). In 12.1 this wan
working.
