Depending on your VM you'll need to enable GPU passthrough (sometimes erroniously labeled "3D acceleration" or something), and then install the corresponding GPU drivers in the guest VM.

I believe this opens up the host device to vulnerabilities if the VM gets infected: https://security.stackexchange.com/questions/162122/gpu-pass...

Yeah, probably. DMA is always an issue when you're using PCI for graphics, so caveat emptor.

Hmm, in theory what if I used a dedicated GPU just for the VM that was disabled on the host. I don't know the space of these exploits well enough to know if there's an obvious attack that still leaves the host open to.
