  I've not yet been able to reproduce this. I've tried  2- and 3-vCPU 
10.1/i386 guests on an Intel E3-1220 v3 (single and dual virtio-blk 
disks), and a 2 vCPU guest on an AMD Sempron 3850 APU. Buildworlds with 
-j set to the number of vCPUs have completed fine.

  The Intel system was using file-backed images on ZFS, while the AMD 
system was on UFS. The guests were UFS. The console was to stdout in a 
tmux session that was mostly backgrounded.

  Was there anything particular with your buildworld ? (-j settings, etc)

  Also, if the guest looks like it hangs, you can extract the RIPs with
   bhyvectl --get-rip --cpu=0 --vm=<vmname>
   bhyvectl --get-rip --cpu=1 --vm=<vmname>

  This might give a hint as to where the guest is spinning.

later,

Peter.
