help installing bhyve guest

[Aryeh Friedman]

I am attempting to make the following install script to work:

truncate -s 80G disk
ifconfig tap3 down
ifconfig tap3 up
/usr/sbin/bhyvectl --vm=lts --destroy
/usr/sbin/bhyveload -m 4096 -d lts.iso lts
/usr/sbin/bhyve -c 3 -m 4096 -AI -H -P -g 0 -s 0:0,hostbridge -s
1:0,virtio-net,tap3 -s 2:0,virtio-blk,disk -s 3:0,virtio-blk,lts.iso
-S
 31,uart,stdio lts

Note that the final target of the install is Ubuntu 12.04 LTS but I
was using the latest 10-CURRENT release.iso to make sure I was doing
nothing weird.   vmrun.sh works on the second but have not tested the
first.

Currently the only output I get is (and then it freezes):
