[Bug 1525076] Re: delete vm, port mac is not be reset

 

you can workaround the issue by setting the macs of all the VF to 00:00:00:00:00:01 before you start to use them, then libvirt will clean the VF.
The problem is with some driver that don't except 00:00:00:00:00:00

Title:
  delete vm, port mac is not be reset

Status in neutron:
  Invalid

Bug description:
  1 Create a vm with sriov port which use a  fix mac
  2 Delete vm.
  3 Use "ip link show" to see the sriov port's vf mac. we found it not change.

  We think that if we delete vm which use a fix mac ,the port's mac
  should be clear.

      def unplug_hw_veb(self, instance, vif):
          if vif['vnic_type'] == network_model.VNIC_TYPE_MACVTAP:
              # The ip utility doesn't accept the MAC 00:00:00:00:00:00.
              # Therefore, keep the MAC unchanged.  Later operations on
              # the same VF will not be affected by the existing MAC.
              linux_net.set_vf_interface_vlan(vif['profile']['pci_slot'],
                                              mac_addr=vif['address'])

  mac_addr=vif['address'] should be a random one.
