Converting Plugins

This page will address converting plugins:

  • OpenvSwitch to LinuxBridge
  • LinuxBridge to OpenvSwitch

There are two things to note: 1. Running the quantum-server-setup script resets the Quantum database 2. There is currently no migration from one Quantum database to another, that is, if one has a existing Quantum setup for LinuxBridge and they want to move this to OpenvSwitch then it is not possible. The networks, subnets etc. will need to be recreated.

OpenvSwitch to LinuxBridge

1. Stop all running instances

2. Terminate the OpenvSwitch services

   chkconfig openvswitch off
   service openvswitch stop
   chkconfig quantum-openvswitch-agent off
   service quantum-openvswitch-agent stop
   chkconfig quantum-ovs-cleanup off

3. Install linuxbridge plugin and agent

   yum install openstack-quantum-linuxbridge

4. Run the installation scripts selecting linuxbridge as the plugin

   quantum-server-setup
   quantum-dhcp-setup
   quantum-l3-setup

5. Ensure that all Quantum services are configured and running

   service quantum-server restart
   service quantum-linuxbridge-agent start
   chkconfig quantum-linuxbridge-agent on
   service quantum-dhcp-agent restart
   service quantum-l3-agent restart

6. Retstart nova compute

   service openstack-nova-compute restart

LinuxBridge to OpenvSwitch

1. Stop all running instances

2. Terminate the LinuxBridge services

   chkconfig quantum-linuxbridge-agent off
   service quantum-linuxbridge-agent stop

3. Install openvswitch plugin and agent

   yum install openstack-quantum-openvswitch

4. Start openvswitch

   chkconfig openvswitch off
   service openvswitch start

5. Configure the intgration bridges

    ovs-vsctl add-br br-int
    ovs-vsctl add-br br-ex

6. Run the installation scripts selecting openvswitch as the plugin

   quantum-server-setup
   quantum-dhcp-setup
   quantum-l3-setup

7. Ensure that all Quantum services are configured and running

   chkconfig quantum-ovs-cleanup on
   service quantum-server restart
   service quantum-openvswitch-agent start
   chkconfig quantum-openvswitch-agent on
   service quantum-dhcp-agent restart
   service quantum-l3-agent restart

4. Retstart nova compute

   service openstack-nova-compute restart
