Hi all!
I wonder, has anyone run a Linux KVM/QEMU VM and had success with PCI passthrough?
PCI passthrough means that the VM gets exclusive access to specified PCI port(s) such as the x8 PCI slot, or either of the x4 or x2 M.2 slots. The access between VM and PCI device is direct and therefore there is essentially no virtualizer performance overhead at all in the VM’s access to those PCI devices.
If you had success, what configuration did you use on the Linux host system?
Also on the guest side, did QEMU’s default firmware work? So you get what looks like a normal computer with its own UEFI firmware boot in the guest, it boots from the virtual block device, and it’s self-configured thanks to ACPI? Please share any details.
Thanks.
