Description Laszlo Ersek 2010-11-03 06:37:13 EDT

Description of problem:

virtio guest, kvm host:

    # uname -r
    2.6.32-80.el6.x86_64

    # ethtool -i eth0
    Cannot get driver information: Operation not supported

pv guest, xen host:

    # uname -r
    2.6.32-80.el6.x86_64

    # ethtool -i eth0
    Cannot get driver information: Operation not supported

pv on hvm guest (with vif = [ "...,type=netfront" ]), xen host:

    # uname -r
    2.6.32-80.el6.x86_64

    # ethtool -i eth0
    Cannot get driver information: Operation not supported

"ethtool -i" should print the driver name and the bus info.

This bug for RHEL6 is similar to bugs 647187/647196 (netfront/virtio_net) for RHEL4 and to bugs 643292/645646 (netfront/virtio_net) for RHEL5. For RHEL6 only a common bug is submitted, because the fix is a commonly effective backport of the following upstream patch ("ethtool.c" part):
