Hi, Can someone tell my if my understanding is correct or not. Currently, KVM only use IOMMU to allow PCI/PCI Express device to be assigned as a PCI device inside guest OS. So right now guest OS does not see IOMMU as a device, but this may change when IOMMU emulation (I saw some patches on the list) is merged into development branch. -- Thawan Kooburat Graduate Student Department of Computer Science UW-Madison -- 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
