Title:
  Slow network performance since Virtio net drivers are always disabled

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Right now virtio drivers are commented out which leads to abysmally
  slow networking.  We need a flag of somesort in the kernel json (and
  probably image as well for whole image booting) saying whether it
  supports virtio.
