+# 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！

+
+- 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.
