I can try your files or better a patch against current.
Thank you, Mario.

Oleksandr,I would like to try an experiment to try to fix your
problem. If you agree,I could send you my bhyve and vmm.ko files,if
you want. I suspect that they may fix your problem. Let me know if you
want to try.

The BAR size of your device is smaller than a page. Unfortunately, you
can't change it, so there's nothing you can do right now.
I don't know why bhyve validates the BAR size. The commit adding this
check is old [1] and doesn't explain it. What bhyve could do is
rounding up the BAR size to a full page size when allocating
memory for
the BAR.
