Enable GPU pass-through on Linux without a dedicated GPU card.
Enable GPU pass-through on Linux without a dedicated GPU card.
Thanks a lot! I'll check the guides. In my previous tries, only one VM was running while the other wasn't. I believe the GPU settings on the host might be misconfigured.
This could be the solution. Most tutorials rely on a graphical interface, but I’m considering using Ubuntu Server’s host feature now. I recently purchased a Unraid license from my home PC and am testing it in this environment, hoping it will function properly.
Update on the black screen problem: The latest edk2-ovmf UEFI update for Linux might be causing the issue. The fix was released in version 202111-5. Ensure you install at least this version or downgrade if needed. For additional details and solutions, check the link provided. Also, recent VFIO improvements have been successful, so it’s time to address this bug.
Begin by configuring SSH for system management. Modify the kernel settings to bypass video devices at startup via grub's load line adjustment. After that, configure KVM to link PCI passthrough devices with your virtual machines. Gentoo likely offers comprehensive documentation tailored to these steps, though it’s specific to their distribution.
