ok. I tried like this,but it didn't work :
bhyve -S -c sockets=1,cores=2,threads=2 -m 4G -w -H -A \
-s 0,hostbridge \
-s 2,virtio-blk,/mnt/$vmdisk1'p2'/bhyve/img/Linux/ubuntu2210.img,bootindex=1 \
-s 3,virtio-blk,/dev/$vmdisk4 \
-s 4,virtio-blk,/dev/$vmdisk2 \-s 7,fbuf,tcp=0.0.0.0:5919,w=1600,h=950,wait \
-s 8:0,passthru,2/0/0 \
-s 8:1,passthru,2/0/1 \
-s 8:2,passthru,2/0/2 \
-s 8:3,passthru,2/0/3 \
-s 10,virtio-net,tap19 \
-s 11,virtio-9p,sharename=/ \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI_CODE.fd \
vm0:19 < /dev/null & sleep 2 && vncviewer 0:19
I tried specifying the bus ID of the framebuffer and I have used this
xorg.conf file :
