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
