I would expect something like this.
The question however what kind of business is done during the roundtrip.
Could it be something like a soft-interrupt 0x80 to get from userspace
to the kernel? Supossedly this interface is depreciated around 2.4
I'll see if I can augment the exit-code in bhyve.
Catching it with bhyvectl --get-all will probably have too much noise
from running the rest of the system.
