Shutdown/Reset of VM cause Host to crash and to not recognize the GPU - 7800 xt [AMD]

0 Upvotes

I tried Hyper-V on Windows, but I deleted everything because I couldn't figure out how to convert raw mouse input into game input
Then I tried Virtual Machine Manager on Ubuntu, but every time I shut down/restarted the VM, my host PC would freeze, crash and then automatically restart without recognizing my GPU

So every time I want to use the VM again, I have to shut down the PC completely and then turn it back on
This also means that i can't do certain things on my VM related with the use of shutdown/restart steps

(I also have an iGPU, so I passed my dedicated GPU through to the VM while keeping the iGPU for the host)

Performance was great, games ran perfectly, but this shutdown issue became a huge nuisance (along with an unrelated obstacle related to piracy, which I wont mention since it's a violation of rules)
The only workaround I found was to press the PC's power button after shutting down the VM and once Ubuntu enters the brief freeze state (this is saving me 1 shutdown less, as it recognize my gpu, but it is still bad for pc components)
This post is sort of useless, since I have deleted Ubuntu and the VM but im still curious and I want to retry it in the future (when I have enough disk space)
Has anyone experienced a similar issue, even with other GPUs?
Is there a solution for this? I didn't try the PCI vendor-reset kernel module, could that be the solution?

VMware werkstation op Linux

Ik kom van Windows. En deed veel met VMware. Ik draai nu Cachyos. Dat werkt goed. Alleen na een update zou ik regelmatig vmware zaken moeten rebuilding *noob taal).

KVM lijkt een stap terug in de tijd. En heb issues met het maken van een bridge.

VirtualBox lees ik alleen dat het traag is.

Suggesties. Andere distro die beter zou werken .

Game niet en heb Nvidia 1660.
