Yes, the PF driver patch and the VF driver for Intel 82576 NIC will be available next week. Both PF/VF drivers are testing versions. The PF driver patch is based on the lasted kernel IGB driver (drivers/net/igb/), and uses SR-IOV v7 API. The VF driver is a totally new NIC driver, it looks like other normal PCI NIC drivers. > Also, the Xen and KVM people need to agree on the userspace interface > here, perhaps also getting some libvirt involvement as well, as they are > going to be the ones having to use this all the time. I'll keep KVM/Xen people updated on the user level interface and let them comment based on a real usage model of the Intel 82576 NIC after PF/VF drivers are available.
