I tried it and the Serial console was greyed out - I could not select it.

Probably when I would force that upon the FreeBSD loader(8) maybe it will work - but there are other issues.

The Network Type 6 is not supported - so I was not able to create a NAT.

I could start a VM without any networks - but that would render then unusable for me.

I will try again in the future when the libvirt(8) driver for Bhyve is better implemented and more complete.
