Title:
  Macvtap CI fails on Train

Status in OpenStack Compute (nova):
  In Progress
Status in OpenStack Compute (nova) train series:
  Confirmed

Bug description:
  
  MacVtap CI[1] started to fail after merging commit[2]

  
  We think it related to this https://github.com/libvirt/libvirt/commit/b91a33638476cf57d910b6056a8fc11921edd029#diff-28bc83a0c3470bba712dfa6824a79c9d. So they change from setting the admin mac to the effective mac. The problem is that the sriov-nic agent relay on the admin mac to send rpc to the neutron server. If the mac and the pci slot don't much it ignores it and the VM stuck in spawn until timeout
