Does it also report rtl8139 (lshw, ethtool -i eth0)? The host is Ubuntu 10.10 with the 2.6.35-28-server kernel. Libvirt is 0.8.3-1ubuntu19.4, qemu-kvm is 0.12.5+noroms-0ubuntu7.11. Not sure how that relates to "Get kvm version >= 60" (from http://www.linux-kvm.org/page/Virtio) but it's at least a "Kernel >= 2.6.25". The process list shows "-device virtio-balloon-pci", so virtio is at least partially there. But also, "-device rtl8139", so this part of the XML appears not to be taking: <interface type='bridge'> <mac address='00:16:36:89:65:2e'/> <source bridge='br0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> <model type='virtio'/> </interface> Even though, oddly, it's consistently 50% faster with the virtio line than without. The guest is running Ubuntu 11.10 with the 3.0.0-20-virtual kernel. The guest reports: # ethtool -i eth0 driver: 8139cp The physical NIC is an Intel 82576 using the igb driver.
