Unable to configure vlan with "binding:vnic-type direct" when SRIOV multi-queue with updated ixgbe drivers

Solution In Progress - Updated -

Issue

  • Customer need to enable the SR-IOV multiQ, without changing/upgrading the QEMU/libvirt version (libvirt 1.1.1, QEMU 2.1.2), they are only allowed to change the IXGBE driver.
  • They checked the SRIOV support with following IXGBE versions
    • IXGBE v4.03 - they manage to have SR-IOV mutipleQ, but failed to configure VLAN.
    • IXGBE v4.3.13 - they didn't manage to have multipleQ enabled.
  • With later QEMU/livirt versions (libvirt 1.2.17, QEMU 2.3.0) and official (v4.3.13) IXGBE driver - It works fine.
