After 12.1->12.2 upgrade FreeBSD bhyve guest does not start anymore

Hello.

Due to a 12.x specific bug, I run a 11.3 guest using vm-bhyve.
This is its config:

loader="bhyveload"
cpu=1
memory=512M
network0_type="virtio-net"
network0_switch="public"
disk0_type="virtio-blk"
disk0_name="disk0"
disk0_dev="sparse-zvol"
uuid="..."
network0_mac="..."

On monday I upgraded the host from 12.1 to 12.2 and, since then, itwon't boot automatically, but will stop at the loader prompt.

Booting...

Loader variables:

Manual root filesystem specification:
  <fstype>:<device> [options]
      Mount <device> using filesystem <fstype>
      and with the specified (optional) option list.

    eg. ufs:/dev/da0s1a
        zfs:tank
        cd9660:/dev/cd0 ro
          (which is equivalent to: mount -t cd9660 -o ro /dev/cd0 /)

  ?               List valid disk boot devices
  .               Yield 1 second (for background tasks)
  <empty line>    Abort manual input

mountroot>


Then, if I just type "ufs:/dev/vtbd0a" it will start correctly.


Can anyone explain why this happens and how to avoid it?


 bye & Thanks
        av.
