1.显卡ROM准备
需要将显卡ROM上传到/usr/share/kvm/目录，可在PE环境下提取独显ROM
root@pve:~# ls /usr/share/kvm/rx570.rom
/usr/share/kvm/rx570.rom
root@pve:~#
2.虚拟机创建
2.1 ubuntu虚拟机pve配置创建
- 设置主机名和VM ID
- 配置安装的镜像
- 配置主板类型和SCSI类型
- 配置虚拟磁盘信息
- 配置虚拟CPU
- 配置虚拟机内存大小
- 配置虚拟机网络
- 确认虚拟机配置
2.2 在PVE中对ubuntu虚拟机中直通显卡
- 添加显卡PCI
- 添加显卡HDMI声音输出
2.3 在配置文件中调用显卡rom
root@pve:~# cat /etc/pve/qemu-server/102.conf

3. 在ubuntu虚拟机中查看显卡
