I have an instance with Cadence on my Openstack and i need a custom mac address, in order to get Cadence and other license software to work properly.

  1. Change mac address on MySQL on neutron database and table named ports
  2. power off Instance
  3. backup libvirt.xml inside instance folder on Compute node
  4. remove libvirt.xml
  5. restart neutron-server on Controller
  6. restart neutron services on Network Node
  7. restart openvswitch-switch, neutron-plugin-openvswitch-agent
  8. power on Instance
