AFAIK a vmd(8) virtual machine can still have only one virtual CPU. If
I remember correctly the thread on tech@ the "theoretical limit of 512
to the number of allocated vcpus in vmm(4)" should be the global
number of vcpu running, not the cpu per guest (which is still one.)

The thread should be this:
