Ah okay. That's good to know. At least for the Windows 2016 case.

That was a little bit strange, it seemed like the emulated ps/2 devices
just wouldn't work on a Win 7 VM. The "atkbd data buffer full" may be
an indication for not delivered interrupts or something like that.
After I've rebooted the host things suddenly started to work. Maybe
some kind of system inconsistency. It was some 11-CURRENT with about 4
weeks uptime.

It may be a good idea to add a note to the Windows installation guide
at https://people.freebsd.org/~grehan/bhyve_uefi/windows_install.txt
that Window 7 requieres AHCI disks with a blocksize if 512 bytes.
Otherwise the installation will fail with "Windows Setup could not
configure Windows on this computer?s hardware" and Windows Update will
bail out with error 0xc8000247.

Hi Peter,

I've been looking forward to this feature and having a graphical console in Windows for something, thank you for your effort. I'm currently using Bhyve on Freenas 9.10 ( FreeBSD 10.3). I've built from source in FreeBSD 11 r301289 and copied the Bhyve binary over. There were a few other hoops to jump through, but I can now launch Bhyve with the GOP UEFI binary.

If I  execute Bhyve without the fbuf device, Bhyve runs and Windows boots normally. If I include the fbuf,  Bhyve returns without error, but does not run. If I include the XHCI tablet backend, again Bhyve executes and Windows boots as normal.

Am I missing something that is required by fbuf outside of the Bhyve binary?
