    what exactly to you mean when you say: 'Unable to open sr-iov' ?
    it may be that the driver changed between versions and the method you tried does not work anymore

    generally sr-iov works either via kernel module parameters or via "echo X > /sys/bus/pci/devices/DEVICEID/sriov_numvfs" where X is the number of virtual functions and DEVICEID is the pci id e.g. 0000:00:0F.0
