我做了一个插件 可以试试

1. I make a workaround in my plugin, you can just install the plugin and have a try. The plugin supports unRAID 6.11.0~6.11.5 and 6.12.0-rc1, 6.12.0-rc2 2. The PF (00:02.0) could be used by Unraid host. And the VFs(00:02.x) are only used for passthrough to VMs

写了一个支持11代12代intel GPU开启SR-IOV的插件， GitHub地址：https://github.com/zhtengw/unraid-i915-sriov 在unraid插件安装页面，输入此链接https://raw.githubusercontent.com/zhtengw/unraid-i915-sriov/master/i915-sriov.plg安装插件，然后重启即可使用。 插件支持unRAID版本：6.11.0~6.11.5, 6.12.0-rc1, 6.12.0-rc2

Hi, Simon. I created a bug report. I was trying to make iGPU SR-IOV work on unRAID. Then I built the custom kernel image mentioned above and also make a plugin(https://github.com/zhtengw/unraid-i915-sriov). After install the i915-sriov module, we can see several VFs in graphic devices. Then I can passthrough a VF to VM. The issue I met is, when a iGPU VF passthrough to VM, it cannot be recognized in the guest system. I enabled XML VIEW in VM settings, and found out that the PCI address in VM is the same as host. <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x00' slot='0x02' function='0x1'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x1'/> </hostdev> It is not true. Because the VM do not have a PF device, the VF pci address (like 0000:00:02.1) won't make the device work. Then I changed the address to 0000:00:02.0, and the guest system recognized the graphics card and made it work. So, I modify the the file /usr/local/emhttp/plugins/dynamix.vm.manager/include/libvirt.php: line 813 on every boot. sed -i "s/\(strSpecialAddress.*\)\$gpu_function/\1\"0\"/" /usr/local/emhttp/plugins/dynamix.vm.manager/include/libvirt.php Then the VM with iGPU VF works fine. I think it is a bug for passthrough iGPU's PCI address.

**edit** Now iGPU SR-IOV is supplied by a unRAID plugin named i915-sriov(https://github.com/zhtengw/unraid-i915-sriov). The custom kernel image is only for testing. **edit** Hi, all. I have noticed that unRAID 6.11.5 is running with linux-5.19, which can build against the i915-sriov module. So I build this custom kernel image. I have tested with i3-12100 with Windows 10 guest, and the iGPU VF works fine. Link: https://github.com/zhtengw/i915-sriov-dkms/releases/tag/v5.19-unraid
