As you know, SR-IOV for Linux have been in 2.6.30, so then you can use upstream KVM and qemu-kvm(or recent released kvm-85) with 2.6.30-rc3 as host kernel. And some time ago, there are several SRIOV related patches for qemu-kvm, and now they all have been checked in. And for KVM, the extra document is not necessary, for you can simple assign a VF to guest like any other devices. And how to create VF is specific for each device driver. So just create a VF then assign it to KVM guest is fine. -- regards Yang, Sheng -- 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
