PVE下联想m4500q直通i5-4590t核显

开启IOMMU和硬件直通功能

1、编辑GRUB文件

nano /etc/default/grub

将GRUB_CMDLINE_LINUX_DEFAULT 一行修改为

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt initcall_blacklist=sysfb_init pcie_acs_override=downstream"

2、更新 GRUB

proxmox-boot-tool refresh

3、加载内核模块

nano /etc/modules

增加如下内容

vfio
vfio_iommu_type1
vfio_pci

4、重启 PVE

5、验证是否成功启用IOMMU

dmesg | grep -e DMAR -e IOMMU

输出以下类似内容

[ 0.009882] ACPI: DMAR 0x00000000DA9CF930 0000B8 (v01 LENOVO TC-FH 00001570 INTL 00000001)

6、验证是否启用IOMMU中断重映射

dmesg | grep remapping

输出类似以下内容

[ 0.116409] DMAR-IR: Queued invalidation will be enabled to support x2apic and Intr-remapping.
[ 0.116924] DMAR-IR: Enabled IRQ remapping in x2apic mode

显卡直通

1、屏蔽驱动

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

添加以下内容

# Intel
blacklist snd_hda_codec_hdmi
blacklist snd_hda_intel
blacklist snd_hda_codec
blacklist snd_hda_core

2、查看显卡和声卡ID

lspci -nn | grep VGA

得到如下内容

00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)

则显卡ID为8086:0412

lspci -nn | grep Audio

得到以下内容

00:03.0 Audio device [0403]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [8086:0c0c] (rev 06)

则声卡ID为8086:0c0c

3、将ID写入vfio配置

nano /etc/modprobe.d/vfio.conf

添加如下内容

options vfio-pci ids=8086:0412,8086:0c0c

4、更新内核

update-initramfs -u

5、重启

6、检查 vfio-pci 是否应用成功

lspci -nnk

得到

00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)
	DeviceName:  Onboard IGD
	Subsystem: Lenovo Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [17aa:309e]
	Kernel driver in use: vfio-pci
	Kernel modules: i915
00:03.0 Audio device [0403]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [8086:0c0c] (rev 06)
	Subsystem: Lenovo Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [17aa:309e]
	Kernel driver in use: vfio-pci
	Kernel modules: snd_hda_intel

其中的Kernel driver in use: vfio-pci 表示成功

创建Win10虚拟机

1、不启用虚拟机的开机自启动

2、系统设置完全保持默认，不修改

3、磁盘类型选择IDE，无缓存

4、CPU的类别选择成host

5、内存设置中打开高级，关闭Ballooning设备

6、添加声卡pci设备

7、不在虚拟机设置中添加显卡pci设备，直接修改虚拟机的配置文件

nano /etc/pve/nodes/vm226/qemu-server/228.conf

在文件的最后添加

args: -device vfio-pci,host=00:02.0,x-igd-opregion=on

安装驱动

直接在Intel的官网上下载最新驱动，打开Win10的远程桌面，利用mstsc连接到远程桌面并安装驱动
