--- Comment #2 from Bob Grant <bgfbsd@foob.us> ---
I read in one related thread about the virtio-random spinning 100% cpu.  All my
hangs took place on a 1 vCPU VM.  

I just tested on a 2 vCPU VM and the system boots successfully.  I'm going to
test a 1vCPU VM for a couple of hours and see if it eventually gets past the
hang.  

It would appear that there is an unfortunate interaction with a single CPU and
and the virtio-random kernel module.
