can u help me to found what is wrong please :



so this my config VM :

args: -set drive.drive-scsi0.readonly=on -drive 'file=/dev/mapper/pve-vm--100--disk--0,if=none,id=drive-usb0,format=raw,cache=none,aio=native,detect-zeroes=on' -device 'usb-storage,drive=rive-usb0,bootindex=1,removable=on'

Currently, your passthrough setting is not yet applied and this might be (one of) the reason(s) that it is not working for you. If the configuration file has a [PENDING] section, you need to shut down the VM and wait until the changes are applied (no longer orange in the web interface). Sometimes this does not happen and you need to change something and change it back while the VM is not running.

Hello thanks to help me


so on my hardware settings i got all black no orange config :




and still got the same error on my VM :

if i do a linux LCPI :




i can see my graphics card

but the linux don't start on it ?

There are two VGAs: 00:01.0 (virtual) and 01:00.0 (nvidia). VM is probably using the first one. Change Display from Default to None or add a virtual serial port and use that as Display. Or maybe you need to enable Primary GPU (for hostpi0) for nvidia?

Hello i don't understand :

u do this conf :



but the serveur start, but i got no screen :'(




SSH works but no screen !



im stuck here :/

 

[leesteken]

No screen with noVNC is good, now there is just one VGA. I don't know what you need to do for NVidia GT710 to work.
If you want two VGAs (one virtual with noVNC) then you need to tell Linux VM to use second VGA (maybe via xorg.conf?).
Have you tried enabling Primary GPU (for PCI device (hostpci0))? Have you tried installing nvidia drivers in VM?

My way is start the VM with graphics on VNC on other computer.

not on the PROXMOX serveur.
