As you can see,each vm has a unique ID (connect= ed with the vncviewer instance) and the vncviewer window is launched as soo= n as the bhyve vm is called...and my Geforce RTX 2080 ti is passed through = inside the vm.

First of all,you could use a more flex= ible technique than using the pptdevs on /boot/loader.conf. I would use a s= cript like this :

1)

if != pciconf -l pci0:18:0:0 | grep -q "^ppt"; then
echo "18= /0/0 is not attached to ppt,attaching..."
devctl clear driver -f pc= i0:18:0:0
devctl set driver -f pci0:18:0:0 ppt

2) I would n= ot like to use vm-bhyve. It adds only some confusion...

Good afternoon everyone.

I am trying to have VMs with GPU passthrou= gh. The setup is a Dell server with NVidia Quadro RTX 6000/8000 installed a= lready. I have checked the device IDs and put pptdevs in place

# cat= /boot/loader.conf
pptdevs=3D"18/0/0 19/0/0"
pptdevs2=3D&qu= ot;72/0/0 73/0/0"

this is showing the GPUs as pptdev on the pci= conf

#END

however, when I start the vm (for OS install= ation to start with), it shows it is running but I am unable to access the = VNC for a while, then when I finally manage to connect via VNC, there is no= thing on the screen, just blank dark screen

Mar 24 13:59:26: starting bhyve (run 1)

based on what I can se= e, and a little out of desparation, I decided to run the installer in the f= oreground, and below is what I got

# vm install -f jagadish FreeBSD-= 14.2-RELEASE-amd64-disc1.iso
Starting jagadish
=C2=A0 * found guest i= n /mnt/VMs/jagadish
=C2=A0 * booting...
fbuf frame buffer base: 0x112= 245400000 [sz 16777216]

it stays there for as long as I wait until I= poweroff the vm.

tried with Debian installer,
# vm install -f j= agadish debian-12.5.0-amd64-netinst.iso
Starting jagadish
=C2=A0 * fo= und guest in /mnt/VMs/jagadish
=C2=A0 * booting...
fbuf frame buffer = base: 0x2747e2400000 [sz 16777216]


ideally I need to install Deb= ian for my user base on these GPU based systems. But even that is proving t= o be impossible since the installer does not move any further from where it= is.

Any thoughts/ideas/suggestions what I else I can try to make th= is work? Anything that you have tried that worked? have I missed something?=

Would appreciate any and all thoughts/suggestions
