Hi,
I should have mentioned at the start - the disk image system ran ZFS
as does the freebsd host. I tried to boot the image like this:
sh /usr/share/examples/bhyve/vmrun.sh -c 4 -m 4096M -t tap0 -d
disk.img diskimage
It loads the spash screen and tries to boot but then drops me to the
mountroot prompt after a screen or so of output:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Trying to mount root from zfs:zroot/ROOT/default []...
Mounting from zfs:zroot/ROOT/default failed with error 5.
Loader variables:
vfs.root.mountfrom=zfs:zroot/ROOT/default
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 /)

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
I've tried various combinations for mountroot but I have no idea how
to make it see zfs:zroot/ROOT/default which is what it was on the
machine I got the image from.

Please can anyone advise how to make the image boot?
