I have installed the driver separately on my pv-ops kernel. [r...@211052610-f-cpu ~]# ethtool -i eth driver: ixgbe version: 2.0.75.7-NAPI firmware-version: 0.9-3 bus-info: 0000:05:00.0 I have attached a log on when the drivers loads. There is a bit more debugging information enabled. You can see that the driver loads at first on devices 0000:02:00.0 and 0000:02:00.1 which are 82598 devices and don't support SRIOV. So the driver switches off SRIOV. When it loads it on the 82599 which sits on 0000:05:00.0, it does not even have the SRIOV parameter enabled anymore, even though I load the driver with 'modprobe ixgbe max_vfs=4'. Thanks, Anna
