I ran the procsystime dtrace script on bhyve when it was chewing up all
the CPU in vCPU=2 mode, and this is what I see for about 10s of runtime:
root at olive:/usr/share/dtrace/toolkit # ./procsystime -n bhyve -aT

Not sure if that helps or not. Hotkernel shows the cpu in the
kernel`acpi_cpu_c1 call most of the time, normal ?
