Depends on how your setting up bhyve for example PetiteCloud limits it to
no more then a 1 to 1 ratio of real to virtual cpu (after playing with
something I will be posting about later today [me and Dee have the policy
of no pronouncements] I am seriously thinking making this n vcpu to 1 real
cpu... what do people think the best way to implement and the right ration
for this is...)
