N100 PVE WIN11 虚拟机HDMI直出画面

修改grub启动参数

nano /etc/default/grub

添加

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"

内核模块加载模块命令

echo -e "vfio\nvfio_iommu_type1\nvfio_pci\nvfio_virqfd" >> /etc/modules

update-grub

update-initramfs -u -k all

安装WIN11跳过联网命令
按Shift+F10

oobe\bypassnro.cmd

核显HDMI直通WIN11

nano /etc/modprobe.d/pve-blacklist.conf

添加以下代码

blacklist i915
blacklist snd_hda_intel
options vfio_iommu_type1 allow_unsafe_interrupts=1

找出PCI显卡号码

root@pve:/# lspci -n | grep -E "0300"
00:02.0 0300: 8086:46d1

写入模块

echo "options vfio-pci ids=8086:46d1" >> /etc/modprobe.d/vfio.conf

4dao14.rom放入位置 /usr/share/kvm/
虚拟机配置文件位置 /etc/pve/qemu-server

hostpci0: 0000:00:02.0,legacy-igd=1,romfile=4dao14.rom
hostpci1: 0000:00:1f.3
#如果已经直通硬盘，需要把已经直通的pci号码修改为3如 hostpci3: 0000:00:17.0

display显卡设置为none

update-initramfs -u -k all

reboot
