bhyve in -current 4/14/13 can no longer support FreeBSD stable install

Hey guys,

I've been trying to get bhyve to install FreeBSD-stable for the past day 
on a -current machine:

FreeBSD dan 10.0-CURRENT FreeBSD 10.0-CURRENT #0 r248291: Fri Mar 15 
00:58:03 PDT 2013     root at dan:/usr/obj/usr/trees/head/sys/GENERIC amd64

The stable snapshot I'm using to install is from here:

What will happen is during the extract process the install will hang.  
No network IO happens and on the host I see bhyve's CPU hit 100% for 
each core assigned.

For reference this is the bhyve command invoked via Neel's "".

     0 3915 3908   0 103  0 2122208 103428 -        R+    2 1048:45.75 
/usr/sbin/bhyve -c 2 -m 2048 -M 0 -AI -H -P -g 0 -s 0:0,hostbridge -s 
1:0,virtio-net,tap0 -s 2:0,virtio-blk,../freebsd-stable.img -s 
-S 31,uart,stdio freebsd-stable

I tried to gdb the bhyve process but that was bad news.  Is there a set 
of steps usually taken to help pinpoint what is going on when we this state?

thank you,
