# GPU SR-IOV guest configure（显卡虚拟化 虚拟机设置）
|
||
|
||
|
||
|
||
## Linux Guest Configure （Linux 虚拟机设置）
|
||
|
||
- sugesst your guest kernel >= 6.2 ( 建议内核版本 >= 6.2 )
|
||
- disable secure boot ( 关闭安全启动 )
|
||
- must use Q35 chip (必须使用q35芯片组)
|
||
- Disable balloon (关闭内存共享)
|
||
- Must use OVMF UEFI ( 必须使用UEFI启动 )
|
||
- Add sriov gpu after install sriov i915 driver (安装驱动以后再添加虚拟显卡)
|
||
|
||
### I will be use debian 12 to do this ( 接下来我用 Debian 12 代号 bookworm 来演示 )
|
||
|
||
- Add backports sources (添加 `backports` 源)
|
||
|
||
because debian 12 default kernel 6.1,so need install new kernel (因为debian 12 默认内核版本较低，需要添加backports源，安装较新的内核，我测试的版本 6.4可用)
|
||
|
||
**Plz use mirrors fit your network. I use ustc mirrors!**
|
||
|
||
```
|
||
echo "deb http://mirrors.ustc.edu.cn/debian bookworm-backports main non-free-firmware" >> /etc/apt/sources.list
|
||
```
|
||
|
||
- Update your system 更新你的系统
|
||
|
||
```
|
||
# apt update
|
||
```
|
||
|
||
- install new kernel 安装新内核
|
||
|
||
```
|
||
# apt install linux-headers-6.4.0-0.deb12.2-amd64
|
||
```
|
||
- 更新 initramfs
|
||
|
||
```
|
||
# update-initramfs -u -k all
|
||
```
|
||
|
||
- 重启
|
||
|
||
```
|
||
# reboot
|
||
```
|
||
|
||
### install i915 sriov drivers 接下来打 `i915` 驱动打补丁
|
||
|
||
- git sources 下载源码
|
||
|
||
```
|
||
cd /usr/src/
|
||
git clone https://github.com/strongtz/i915-sriov-dkms i915-sriov-dkms-6.4
|
||
```
|
||
|
||
|
||
- edit file 编辑源文件
|
||
|
||
```
|
||
edit /usr/src/i915-sriov-dkms-6.4/dkms.conf with the following:
|
||
PACKAGE_NAME="i915-sriov-dkms"
|
||
PACKAGE_VERSION="6.4"
|
||
```
|
||
|
||
|
||
- start dkms 开始打补丁
|
||
|
||
```
|
||
dkms install --force -m i915-sriov-dkms -v 6.1
|
||
```
|
||
- edit kernel cmdline 编辑内核参数
|
||
|
||
```
|
||
edit /etc/default/grub with the following:
|
||
GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.enable_guc=3"
|
||
```
|
||
|
||
- update initramfa 更新 initramfs
|
||
|
||
```
|
||
# update-grub
|
||
# update-initramfs -u
|
||
```
|
||
|
||
|
||
- poweroff 关机
|
||
```
|
||
# poweroff
|
||
```
|
||
|
||
### guest add sriov igpu 虚拟机添加虚拟显卡
|
||
|
||
- boot your guest 启动虚拟机
|
||
- check 检查是否工作
|
||
|
||
**Running in SR-IOV VF mode** 说明已经工作在 sr-iov 模式了！
|
||
|
||
```
|
||
# dmesg |grep i915
|

||
```
|
||
|
||
- done 完成✅
|
||
|
||
## Windows Guest 设置
|
||
|
||
- install win10 guest 正常安装虚拟机
|
||
- you can add sriov gpu 可以添加虚拟显卡
|
||
- disable balloon 关闭内存共享
|
||
- OVMF UEFI boot 必须使用 UEFI 启动
|
||
- q35 chips 必须使用q35芯片组
|
||
- SR-IOV GPU could be set primary GPU after install intel gpu drivers 安装驱动以后才能设置成主显卡，注意此时的vnc就不可用了，搞好网络设置和 rdp 再这么干
|
||
- SR-IOV GPU must set pci-Express 这么做会不会出现 43 bug！这样在windows guest 里面的pci 地址会和host一致，这样不会出错，我试了好久。如果不这么设置会出现43错误，要重新启用显卡才能清除错误！我记得gvt 就不会影响，这个应该是系统的bug！
|
||
|
||
安装好虚拟机以后 ，进去设置好远程桌面，装好显卡驱动！就完成了！
|
||
|
||
After installed windows vm, must set rd desktop or other remote desk, then install new intel gpu driver.
