- 配置 Windows 11 虚拟机
直接挂载镜像并添加 TPM v2.0 提示设备不受支持无法安装。这里采用 Rufus 烧录镜像干掉 TPM 直通 U 盘给虚拟机安装。
创建虚拟机时，BIOS 选择 SeaBIOS，Machine 选择 q35，Disks Bus/Device 选择 SCSI 并勾选 Discard 和 SSD emulation，Network Model 选择 VirtIO。
安装完成后在 Windows 虚拟机内启用远程桌面并关机。
在虚拟机配置页面添加 PCI Device 选择 0000:74:00.0（显卡）并勾选 Primary GPU 和 PCI-Express，再添加一个 0000:74:00.1 (声卡)。将 Display 的 Graphic card 修改为 none。直通你的键盘和鼠标。
编辑 /etc/pve/qemu-server/.conf，在显卡后追加 romfile=vbios_1002_1681.bin。
sed -i 's/0000:74:00.0,pcie=1,x-vga=1/0000:74:00.0,pcie=1,x-vga=1,romfile=vbios_1002_1681.bin/g' /etc/pve/qemu-server/<VM ID>.conf启动虚拟机，通过远程桌面连接后下载驱动程序并安装（安装时选择 Driver Only）。
至此，核显直通流程基本完成。后续虚拟机每次关机之前须通过远程桌面手动弹出显卡及声卡，否则会导致 Proxmox VE 强制重启！
@cfboss 主机
PVE 7.4-3，虚拟机Windows 10，直通成功。但是似乎虚拟机重启会连带PVE主机一起重启，目前没找到什么解决方案。
