Hello, there are some problems in configuring the virtual graphics card for PVE.
My machine configuration is i9-7940X and RTX2080ti 12GB

Now I have installed the graphics driver


and mdevctl types shows

And configure VM 100

Hi,

can you post the complete output of 'dmesg' here?
also could you try to remove the mdev instances before starting the vms?

echo 1 > /sys/bus/mdev/devices/$mdev_UUID/remove

你好，

你能在这里发布'dmesg'的完整输出吗？
您也可以尝试在启动虚拟机之前删除 mdev 实例吗？
