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
etc/pve/qemu-server/100.conf

please help me ,thanks
 
Hi,

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

Code:
echo 1 > /sys/bus/mdev/devices/$mdev_UUID/remove
 
XXXX - VMID
pci_device_id - your id
pci_id - your id

nano /etc/vgpu_unlock/profile_override.toml
Bash:
[profile.nvidia-256]
num_displays = 1
display_width = 1920
display_height = 1080
max_pixels = 2073600
cuda_enabled = 1
frl_enabled = 1
framebuffer = 0x76000000
pci_device_id = 0x1E30
pci_id = 0x1E3012BA

[mdev.00000000-0000-0000-0000-000000000XXXX]
frl_enabled = 0


nano /etc/pve/qemu-server/XXXX.conf
add line:
Bash:
args: -uuid 00000000-0000-0000-0000-00000000XXXX

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?

[代码]
回声 1 > /sys/bus/mdev/devices/$mdev_UUID/remove
[/代码]
○oh I'm so stupid, I should have uploaded the attachment to you
