GPU Passthrough support #24

Open matbee-eth opened 5 months ago

matbee-eth commented 5 months ago

Is it possible to pass through a dedicated GPU to the VM now that it uses KVM as a backend?

While it is currently not officially supported or very well tested, you can try to use the PCI pass-through functionality we added for SR-IOV. If you adapt the instructions to only deal with your dedicated GPU, it might work.

If you need any further assistance with this, feel free to reach out to service@cyberus-technology.de!

The docs mentioned Intel quite a lot and I use AMD so I didnt even attempt

You need to adapt the tutorial a little bit. In a nutshell, you need to make sure that the device is claimed by the vfio-pci driver, and pass the device to virtualbox via --attach-vfio. Hope this helps.
