显卡直通

修改Grub：
vim /etc/default/grub

英特尔：
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb textonly nomodeset initcall_blacklist=sysfb_init"

AMD：
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb textonly nomodeset initcall_blacklist=sysfb_init"

update-grub

加载模块
vim /etc/modules

添加以下几个模块，直接复制即可。
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

阻止驱动加载（显卡直通时才需要操作
因为pve启动时会尝试加载显卡驱动，为了避免pve占用显卡，需要阻止pve的显卡驱动加载。

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

添加以下内容
# block AMD driver
blacklist radeon
blacklist amdgpu

# block NVIDIA driver
blacklist nouveau
blacklist nvidia
blacklist nvidiafb

# block INTEL driver
blacklist snd_hda_intel
blacklist snd_hda_codec_hdmi
blacklist i915

# IOMMU interrupt remapping
echo "options vfio_iommu_type1 allow_unsafe_interrupts=1" > /etc/modprobe.d/iommu_unsafe_interrupts.conf
echo "options kvm ignore_msrs=1" > /etc/modprobe.d/kvm.conf

更新内核
update-initramfs -u

# pve的shell敲lspci -nn 找找你要直通的id
lspci -nn | grep NVIDIA
lspci -nn | grep 5500
03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 14 [Radeon RX 5500/5500M / Pro 5500M] [1002:7340] (rev c5)
lspci -nn | grep 630
00:02.0 VGA compatible controller [0300]: Intel Corporation CoffeeLake-S GT2 [UHD Graphics 630] [8086:3e98] (rev 02)

# 找到显卡后记下硬件id，形式是xxxx:xxxx，比如G5400的核心显卡的硬件id是8086:3e90。

vim /etc/modprobe.d/vfio.conf

# 添加以下内容注意！！！！把10de:1381换成你的显卡的硬件id
options vfio-pci ids=10de:1381,10de:0fbc disable_vga=1

# 重启机器
reboot

安裝pve tools

apt install git -y
export LC_ALL=en_US.UTF-8
git clone https://github.com/ivanhao/pvetools.git
cd pvetools
./pvetools.sh

---
Windows VM Settings

# /etc/pve/qemu-server/<vmid>.conf

args: -cpu 'host,hv_time,kvm=off,hv_vendor_id=null,-hypervisor,rdtscp=off'

cpu: host,hidden=1,flags=+pcid
