The reason that I did it this way was because my original intention was
to make it work with virt-manager smoother. However, I think you're
right, it's better to error on configuration we cannot properly support
instead of letting users have false expectation.

It will make creation of new VM via virt-manager fail with the default
configuration, but it's not critical because user still have to modify
some hardware settings anyway to make it work with bhyve (i.e.: drop vnc
and pty console).

Thanks for the review, I'll upload v2 shortly.
