Helpful in tracking what exactly is causing the conflict with your GPU (or other PCI device you're trying to pass through) Instead of having your PCI device release script run on boot via crontab, you can use a VM startup script instead to more precisely trigger the release of the PCI device only when the VM that needs it is started. There are currently two vIOMMU implementations available: When passing through a GPU, the best compatibility is reached when using q35 as machine type, OVMF (UEFI for VMs) instead of SeaBIOS and PCIe instead of PCI. The device acts as if it were directly driven by the VM, and the VM detects the PCI device as if it were physically connected. 8.
