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?

Thanks

Hello all, im trying to figure out how to configure the custom properties to enable my NVIDIA card to work in the VM. Its my understanding that the drives dont work because it detects its in a VM......

Im trying to do something like this:

engine-config -s UserDefinedVMProperties="kvmhidden=^(true|false)$;{type=vendor_id;state={^(on|off)$;value=^([0-9])$}}"

But thats clearly not working. If I do this:

engine-config -s UserDefinedVMProperties="kvmhidden=^(true|false)$;vendor_id={state=^(on|off)$;value=^([0-9])$}"

It works but, the options are messed up. Im not sure how to find out the correct syntax to get this to work. Would appreciate any advice.
