PVE9.2 虚拟核显SR-IOV分配飞牛OS使用

DearX

i5-12400安装PVE9后，将核显虚拟到飞牛OS上

使用PVE-Tools虚拟化核显

1. 先使用 https://github.com/PVE-Tools/PVE-Tools-9在PVE上进行核显虚拟化，使用命令 bash <(curl -sSL https://ghfast.top/raw.githubusercontent.com/PVE-Tools/PVE-Tools-9/main/PVE-Tools.sh)运行脚本。
2. 依次选择后完成虚拟化：

4  . 硬件直通与显卡 ( 核显 / NVIDIA / AMD / IOMMU / 磁盘直通 )
1  . Intel 核显虚拟化管理 (SR-IOV/GVT-g)
1  . Intel 11-15代 SR-IOV 核显虚拟化

3. 核显被分成3个虚拟显卡，在飞牛OS的虚拟机上，添加分配出来的虚拟核显，从第二个开始选择，比如 0000:00:02.1，不能选择 0000:00:02.0。

安装驱动

1. 飞牛中应用中心安装驱动：i915-sriov-dkms

2. 此时飞牛影视等还是会调用失败，选择启动GPU会显示：获取/设置 GPU 失败

3. 终端中的查看状态，GuC失败

   ~# dmesg | grep -i i915
   [    1.765555] i915: You are using the i915-sriov-dkms module, a ported version of the i915/xe module with SR-IOV support.
   [    1.765556] i915: Please file any bug report at https://github.com/strongtz/i915-sriov-dkms/issues/new.

   [    1.908779] i915 0000:01:00.0: [drm] *ERROR* Device initialization failed (-19)
   

4. 查看启动参数，默认未配置 i915 GuC 及相关 IOMMU 参数

   ~# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
   

5. 修改grub，将原先的GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"修改

sudo nano /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=on iommu=pt i915.enable_guc=3 module_blacklist=xe"

6. 更新配置并重启

sudo update-grub
sudo update-initramfs -u
sudo reboot

7. 验证驱动

8.在影视中选择首选GPU不再报错，验证转码播放正常调用GPU
