# -- Background
|
||||
|
||||
The quantum openvswitch plugin is a simple plugin that allows you to manage
|
||||
connectivity between VMs on hypervisors running openvswitch.
|
||||
|
||||
The quantum openvswitch plugin consists of two components:
|
||||
|
||||
1) The plugin itself: The plugin uses a database backend (mysql for now) to
|
||||
store configuration and mappings that are used by the agent.
|
||||
|
||||
2) An agent which runs on the hypervisor (dom0) and communicates with
|
||||
openvswitch. The agent gathers the configuration and mappings from the
|
||||
mysql database running on the quantum host.
|
||||
|
||||
The sections below describe how to configure and run the quantum service with
|
||||
the openvswitch plugin.
|
||||
|
||||
# -- Nova configuration
|
||||
|
||||
- Make sure to set up nova using flat networking. Also, make sure that the
|
||||
integration bridge (see below under agent configuration) matches the
|
||||
flat_network_bridge specified in your nova flag file. Here are the relevant
|
||||
entries from my nova flag file.
|
||||
--network_manager=nova.network.manager.FlatManager
|
||||
--flat_network_bridge=xapi1
|
||||
|
||||
# -- Quantum configuration
|
||||
|
||||
Make the openvswitch plugin the current quantum plugin
|
||||
|
||||
- edit ../../plugins.ini and change the provider line to be:
|
||||
provider = quantum.plugins.openvswitch.ovs_quantum_plugin.OVSQuantumPlugin
|
||||
|
||||
# -- Database config. The OVS quantum service requires access to a mysql
|
||||
# database in order to store configuration and mappings that will be used by
|
||||
# the agent. Here is how to set up the database on the host that you will be
|
||||
# running the quantum service on.
|
||||
|
||||
MySQL should be installed on the host, and all plugins and clients must be
|
||||
configured with access to the database.
|
||||
|
||||
To prep mysql, run:
|
||||
|
||||
$ mysql -u root -p -e "create database ovs_quantum"
|
||||
|
||||
Make sure any xenserver running the ovs quantum agent will be able to communicate with the host running the quantum service:
|
||||
|
||||
//log in to mysql service
|
||||
$ mysql -u root -p
|
||||
//grant access to user-remote host combination
|
||||
mysql> GRANT USAGE ON *.* to root@'yourremotehost' IDENTIFIED BY 'newpassword';
|
||||
//force update of authorization changes
|
||||
mysql> FLUSH PRIVILEGES;
|
||||
|
||||
# -- Plugin configuration.
|
||||
|
||||
- Edit the configuration file (ovs_quantum_plugin.ini). Make sure it matches
|
||||
your mysql configuration. This file must be updated with the addresses and
|
||||
credentials to access the database. This file will be included in the agent
|
||||
distribution tarball (see below) and the agent will use the credentials here
|
||||
to access the database.
|
||||
|
||||
# -- Agent configuration
|
||||
|
||||
- Create the agent distribution tarball
|
||||
|
||||
$ make agent-dist
|
||||
- Copy the resulting tarball to your xenserver(s) (copy to dom0, not the nova
|
||||
compute node)
|
||||
- Unpack the tarball and run install.sh. This will install all of the
|
||||
necessary pieces into /etc/xapi.d/plugins. It will also spit out the name
|
||||
of the integration bridge that you'll need for your nova configuration.
|
||||
- Run the agent [on your hypervisor (dom0)]:
|
||||
$ /etc/xapi.d/plugins/ovs_quantum_agent.py /etc/xapi.d/plugins/ovs_quantum_plugin.ini
|
||||
|
||||
# -- Getting quantum up and running
|
||||
|
||||
- Start quantum [on the quantum service host]:
|
||||
~/src/quantum-framework$ PYTHONPATH=.:$PYTHONPATH python bin/quantum etc/quantum.conf
|
||||
- Run ovs_quantum_plugin.py via the quantum plugin framework cli [on the
|
||||
quantum service host]
|
||||
~/src/quantum-framework$ PYTHONPATH=.:$PYTHONPATH python quantum/cli.py
|
||||
|
||||
This will show help all of the available commands.
|
||||
|
||||
An example session looks like this:
|
||||
|
||||
$ export TENANT=t1
|
||||
$ PYTHONPATH=. python quantum/cli.py -v create_net $TENANT network1
|
||||
Created a new Virtual Network with ID:e754e7c0-a8eb-40e5-861a-b182d30c3441
|
||||
$ export NETWORK=e754e7c0-a8eb-40e5-861a-b182d30c3441
|
||||
$ PYTHONPATH=. python quantum/cli.py -v create_port $TENANT $NETWORK
|
||||
Created Virtual Port:5a1e121b-ccc8-471d-9445-24f15f9f854c on Virtual Network:e754e7c0-a8eb-40e5-861a-b182d30c3441
|
||||
$ export PORT=5a1e121b-ccc8-471d-9445-24f15f9f854c
|
||||
$ PYTHONPATH=. python quantum/cli.py -v plug_iface $TENANT $NETWORK $PORT ubuntu1-eth1
|
||||
Plugged interface "ubuntu1-eth1" to port:5a1e121b-ccc8-471d-9445-24f15f9f854c on network:e754e7c0-a8eb-40e5-861a-b182d30c3441
|
||||
$ PYTHONPATH=. python quantum/cli.py -v plug_iface $TENANT $NETWORK $PORT ubuntu2-eth1
|
||||
Plugged interface "ubuntu2-eth1" to port:5a1e121b-ccc8-471d-9445-24f15f9f854c on network:e754e7c0-a8eb-40e5-861a-b182d30c3441
|
||||
|
||||
Now you should have connectivity between ubuntu1-eth1 and ubuntu2-eth1..
|
||||
|
||||
# -- Other items
|
||||
|
||||
- To get a listing of the vif names that the ovs quantum service will expect
|
||||
them in, issue the following command on the hypervisor (dom0):
|
||||
$ for vif in `xe vif-list params=uuid --minimal | sed s/,/" "/g`; do echo $(xe vif-list params=vm-name-label uuid=${vif} --minimal)-eth$(xe vif-list params=device uuid=${vif} --minimal); done
