Quantum
The Quantum project provides "network connectivity as a service". This page tracks Fedora Cloud SIG's effort to maintain Quantum in Fedora.
This page will address the installation and configuration of the following:
- Quantum Server
- Quantum Plugins
The packaging can be found at:
Quantum Server
Installation
The Quantum service is installed as follows:
#> sudo yum install openstack-quantum
Configuration
The Quantum service requires the installation and configuration of a database. This can be achieved by running the following:
#> sudo quantum-server-setup
This will ensure that Quantum database is installed, started and configured. In addition to this the user will be requested to supply the relevant plugin. The plugins are discussed below.
OpenStack
Please note that the script quantum-server-setup will update the nova configuration file. Keystone Integration - TBD
Quantum Plugins
The plugin is responsible for the dynamic configuration of the switches. The following plugins are supported:
- Cisco
#> sudo yum install openstack-quantum-cisco
- Linux Bridge
#> sudo yum install openstack-quantum-linuxbridge
#> sudo yum install openstack-quantum-nicira
#> sudo yum install openstack-quantum-openvswitch
#> sudo yum install openstack-quantum-ryu
The plugin needs to be installed on all of the nodes.
Configuration
The Quatum plugin must be configured so that it can interface with the Quantum server. This can be achieved by running the following:
#> sudo quantum-node-setup
This will ensure that Quantum plugin is installed, started and configured.
OpenStack
Please note that the script quantum-node-setup will update the nova configuration file. Keystone Integration - TBD
Troubleshooting
Quantum Server
- /etc/quantum/plugins.ini contains the specific plugin module. Check that this matches the intended plugin
- /etc/quantum/quantum.conf contains information relevant to the server. Check that the server is running and that the bind_port is indeed up.
Quantum Plugin
- /etc/quantum/plugins.ini contains the specific plugin module. Check that this matches the intended plugin
- /etc/quantum/quantum.conf contains the specific plugin module. Check that this matches the intended plugin
OpenStack
- It may be useful to look for errors in /var/log/nova/network.log and /var/log/nova/nova-dhcpbridge.log
- Common configuration: /etc/nova/nova.conf contains the relevant quantum configuration.
