本来在PVE9上使用的104-100好好的，没事升级了一下，马上显卡不能用了。因为是小白，查了半天才知道内核升级导致的。
输入：
nvidia-smi
输入：
uname -r
输入：
dkms status
系统的内核是6.14.11-3-pve nvidia安装的内核是6.14.11-2-pve，两个不一样。
如要升级|降级vGPU驱动，则需要先卸载，再安装
nvidia 580.65.05资源下载

# 卸载显卡驱动
./NVIDIA-Linux-x86_64-580.65.05-vgpu-kvm-custom.run --uninstall
# 移除显卡相关程序
apt remove --purge nvidia-*
安装 NVIDIA vGPU_HOST 驱动
在宿主机PVE下安装vGPU的HOST驱动。驱动已做修补，自行将host驱动NVIDIA-Linux-x86_64-580.65.05-vgpu-kvm-custom.run上传到/tmp目录
# 安装用到的依赖包和header头文件
apt install build-essential dkms mdevctl pve-headers-$(uname -r)
# 前往上传驱动的/tmp目录
cd /tmp
# 赋予执行权限
chmod +x NVIDIA-Linux-x86_64-580.65.05-vgpu-kvm-custom.run
# 安装驱动(默认一路回车直至安装完成即可)
./NVIDIA-Linux-x86_64-580.65.05-vgpu-kvm-custom.run --dkms -m=kernel
# 安装好后执行重启
reboot随后使用
