Hey

I'm trying to pass the GPU to a vm which I am using for my TV. It works after a complete reboot of the server, but my weekly backup (stop) prevents the GPU from passing through again afterwards.

Does anyone has this already running?
 
This happens to some GPUs when they do not reset properly. If you have an AMD GPU, manually building and installing vendor-reset might help. I believe the latest generation of AMD and NVidia GPUs have reset working much better.
 
I have a GIGABYTE GeForce GTS 450 OC 1GB.
Is there also a workaround for Nvidea cards?

Edit:
It is not really solved. I just decided not to stop the vm when I do the backup.

I've decided to get a new card for a little bit of gaming (like Hacker Simulator) and mainly for the reset problem. Actually nothing super fancy but I have also two cards in mind which are a little bit more expensive/powerful - EVGA GeForce GTX 1660 SUPER SC ULTRA and PowerColor AMD Radeon RX 6600 Fighter.

Or just the GIGABYTE GT 730 2GB GDDR5. Anyone having experience with some of them?
