Hi Vendor ID of Nvidia is usually 10de. You can locate 'vendor ID:product ID' by running lspci command, for example: [root@intel-vfio ~]# lspci -Dnn | grep -i nvidia 0000:03:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK104GL [Quadro K4200] [10de:11b4] (rev a1) 0000:03:00.1 Audio device [0403]: NVIDIA Corporation GK104 HDMI Audio Controller [10de:0e0a] (rev a1) [root@intel-vfio ~]#
In this example, the vendor ID of VGA controller is 10de and the product ID is 11b4 Please bare in mind that you need to enable IOMMU, add pci-stub (prevent the host driver for using GPU device) and disable the default nouveau driver on the host Kernel command line. to do that: 1. Edit host /etc/sysconfig/grub and add the next to GRUB_CMDLINE_LINUX: - intel_iommu=on or amd_iommu=on - pci-stub.ids=10de:11b4,10de:0e0a - rdblacklist=nouveau 2. Regenerate the boot loader configuration using grub2-mkconfig command: # grub2-mkconfig -o /etc/grub2.cfg 3. Reboot the host. 4. Verify configuration: [root@intel-vfio ~]# cat /proc/cmdline BOOT_IMAGE=/vmlinuz-3.10.0-957.5.1.el7.x86_64 root=/dev/mapper/vg0-lv_root ro crashkernel=auto rd.lvm.lv=vg0/lv_root rd.lvm.lv=vg0/lv_swap rhgb quiet pci-stub.ids=10de:11b4,10de:0e0a intel_iommu=on rdblacklist=nouveau LANG=en_US.UTF-8 [root@intel-vfio ~]# After running this, you should be able to passthrough GPU to VM. BTW, why are you using engine-config and not doing it from oVirt UI or using virsh edit command?
