I think hostdev "1" is a typo? I think normally "0" is used. The VM will not
even start for me with "-s 1:0,hostbridge".
Would be nice to get it clarified because a few forum threads related to the
issue link to this issue.
Anyway, the issue also relevant for me. I've tried various suggests, but I
cannot get keyboard working neither on Windows 10 nor Windows 11.
The command I'm using is:
bhyve \
-c 2 -m 8192 -A -I -u -H -P \
-s 0:0,hostbridge \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \
-s 30:0,xhci,tablet \
-s 3:0,ahci,hd:/data/img/windows10.img,cd:/data/img/null.iso \
-s 30:1,fbuf,tcp=127.0.0.1:5944,vga=off \
-s 31:0,lpc \
windows10
When connecting via VNC mouse works, keyboard does not, and I get:
atkbd data buffer full
messages from bhyve.
Am I doing something obviously wrong, or that a bug in bhyve after all?
