https://bugzilla.kernel.org/show_bug.cgi?id=82761 --- Comment #7 from Alex Williamson <alex.williamson@xxxxxxxxxx> --- I'm guessing this might be the motherboard here: MSI ZH77A-G43 Since you're apparently trying to use VT-d on this system for KVM and therefore presumably device assignment, I'll note that you will never be able to successfully assign the conventional PCI devices separately between guests or between host and guests. The IOMMU does not have the granularity to create separate IOMMU domains per PCI slot in this topology. Also, some (all?) Realtek NICs have some strange backdoors to PCI configuration space that make them poor targets for PCI device assignment: http://git.qemu.org/?p=qemu.git;a=commit;h=4cb47d281a995cb49e4652cb26bafb3ab2d9bd28 -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
