What happens if you load it from /boot/load.conf

Also you shouldn't have to turn on kvm (I do have it turned on but it
should not be required).

Bhyve has a upper limit of 16 vm's that it can run at once but I don't
think this is based on core count of the processor.

I have two Ryzen 5 2600X/MSI machines as far I can tell looking at the
specs (and what I remember when I was deciding to get a 3900X or 2600X)
there is no practical difference, except for core count, from the point of
view of virtualization/bhyve.  One machine is a MSI B450 Tomahawk and the
other is MSI B450 Gaming Pro.   Both machines run bhyve with out any
problem (one of them is my main home office server with 3 vm's on it
[windows and 2 FreeBSD]) and the other is my primary desktop machine and
used for R&D on PetiteCloud (which is a web interface to bhyve and qemu).
