Sorry, for the mess. It was very hard day and I post fe silly posts due to my inattention (and incorrectly selected ssh window).
Finally, I have got only single issue with ixgbe driver there. I can't create VF inside KVM VM. Not with max_vfs param, not with echo 2 > /sys/devices/pci0000:00/0000:00:02.0/0000:03:00.1/sriov_numvfs. Could you help me?
