  bhyveload does the job of what BIOS/boot0/1/2/loader would do on real 
h/w, so it has to be executed each time on restart.

  One optimization to the cycle you mentioned is that bhyvectl --destroy 
only has to be done when the VM is no longer needed i.e you can loop 
with bhyveload/bhyve.

later,

Peter.
