Hello, on a Supermicro H8DGU server with the latest BIOS PCI passtrough fails. I tried to give a two igbvf devices to the domU. pciback is configured and everything locks good until igbvf tries to initialize the PCI device. I have the same error with XEN 4.3, 4.3.1 and the current 4.4-unstable, linux kernel 3.12.0, 3.12.1, 3.9. DomU config: kernel = "/boot/gentoo-DomU" memory =
