Hello to everyone.
what Im trying to do is to set the framebuffer video adapter as primary
graphic card on my bhyve-ubuntu vm instead of the nvidia RTX 2080 ti card
that I have passed through. What I want to do really is to use both the
graphic adapters,but the primary should be the framebuffer and the
secondary the nvidia. I tried different Xorg configurations,but what I've
got is that Xorg failed to display some errors. So,the controller that you
see below should be used as primary inside the ubuntu vm :
00:1d.0 VGA compatible controller: Device fb5d:40fb
while the ones you see below as secondary :
08:00.0 VGA compatible controller: NVIDIA Corporation TU102 [GeForce
RTX 2080 Ti] (rev a1)
08:00.1 Audio device: NVIDIA Corporation TU102 High Definition Audio
Controller (rev a1)
08:00.2 USB controller: NVIDIA Corporation TU102 USB 3.1 Host
Controller (rev a1)
08:00.3 Serial bus controller: NVIDIA Corporation TU102 USB Type-C
UCSI Controller (rev a1)
The script that I use to launch the vm is the following :
#!/bin/sh
setxkbmap it
vms="$(ls /dev/vmm/*)"
vncs="$(ps ax | awk '/vncviewer [0]/{print $6}')"
for vm in $vms; do
session="${vm##*/}"
echo "bhyve session = $session"
echo "vnc session = $vncs"
if ! printf '%s\n' "${vncs}" | grep "${session}"; then
printf 'VNC session not
found,destroying ghost vms\n'
bhyvectl --vm=$session --destroy
else
printf 'Found VNC session %s\n'
"${session},no ghost vms found,not destroying them"
fi
done
vmdisk1=`geom disk list | awk '/^Geom name: /{d=$NF} /^ *ident:
(2015020204055E)/ && d{print d}'`
echo "TOSHIBA External USB 3.0 1.8 TB ; $vmdisk1"
mount -t ufs /dev/$vmdisk1'p2' /mnt/$vmdisk1'p2'
bhyve -S -c sockets=1,cores=2,threads=2 -m 4G -w -H -A \
-s 0,hostbridge \

-s 8:1,passthru,2/0/1 \

-s 8:3,passthru,2/0/3 \

-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI_CODE.fd \
vm0:19 < /dev/null & sleep 2 && vncviewer 0:19
For sure ,on /boot/loader.conf I've added :
/boot/loader.conf
pptdevs="2/0/0 2/0/1 2/0/2 2/0/3"
As I said before,I tried two xorg conf files to achieve the goal. On the
first one I tried to add only the framebuffer,like this :
Section "Files"
ModulePath "/usr/lib/xorg/modules"
FontPath "/usr/share/fonts/X11/misc"
FontPath "/usr/share/fonts/X11/cyrillic"

but it didn't work. This is the log file that shows the errors
reported : https://pastebin.ubuntu.com/p/Gv7wgsDR4K/
I have also removed the xorg.conf file,but it didn't work either. This
is the log file that shows the errors reported :
https://pastebin.ubuntu.com/p/wNcfQTByQm/
Can someone give me some suggestions that can help me to understand
where the mistake is,please,thanks.
