### Choosing the right driver version
This is the tricky part, at the time of writing (Jan 2022), there are three active branches of the NVIDIA vGPU driver. The latest is branch 13 (long term support branch until mid 2024) with driver version 470. I had no luck getting *any* version of that driver to work with vGPU at all but as always - ymmv.
This is the tricky part, at the time of writing (Jan 2022), there are [three active branches](https://docs.nvidia.com/grid/) of the NVIDIA vGPU driver. The latest is branch 13 (long term support branch until mid 2024) with driver version 470. I had no luck getting *any* version of that driver to work with vGPU at all but as always - ymmv.
Branch 12 is a "regular" production branch with support until January of 2022 and has driver version number 460. Lots of people are running that driver in combination with the Linux Kernel 5.15. I got it installed with my gpu, but as soon as I tried to use the gpu in my VM, the display would freeze every 30-ish seconds and `nvidia-vgpu-mgr.service` would report an error similar to `error: vmiop_log: (0x0): XID 43 detected on physical_chid:0x1c, guest_chid:0x14`. At first I thought I messed up some of the driver patches required to get the driver working on kernels newer than 5.11 - so I tried on PVE 6.4 without any patches (5.4 kernel) but got the same errors there. If anyone knows what's causing this error, or even how to fix it, **please** let me know :)
