I'm attempting to setup GPU passthrough to a Win10 guest with an Ubuntu 18.04 host.
I have two GPUs (GTX750Ti and GTX980), as well as integrated graphics. I wish to assign the GTX980 to a VM (VM is configured and Win10 is already installed), but after I've attached the GPU to the VM, it starts crashing at startup. If I detach the GPU, VM works normally again.
Error message is the following:
Code: Select all
Failed to open a session for the virtual machine 980.
The VM session was aborted.
Result Code: NS_ERROR_FAILURE (0x80004005)

Thanks in advance!
