Major Features
Beryllium marked the fourth release of the OVSDB NetVirt project. The release delivers increased code and testing coverage and improved network virtualization integration with OpenStack.
Release Deliverables
- Code quality, stability and usability
- Remove deprecated AD-SAL APIs
- Netvirt updates for flow optimizations and config migration
- ODL SFC and OPNFV SFC integration, application pipeline coexistence
- Increased Neutron parity by adding Security Groups and Metadata support
- Enhanced L3 DVR functionality
- Hardware VTEP southbound support
- Open_vSwitch southbound support for QoS and Queue
- Clustering/HA/Persistence support
- DPDK enhancements to the Southbound and NetVirt to support DPDK
Experimental Deliverables
Experimental support is added for the following features:
- Clustering using the openflowplugin-li plugin. The feature is odl-ovsdb-openstack-clusteraware.
- Network Virtualization DLUX user interface. The feature is the odl-ovsdb-ui.
Target Environment
For Execution
Same as the usual JRE requirements for OpenDaylight
For Development
Same as the usual JDK and Maven requirements for OpenDaylight
Known Issues and Limitations
- OpenStack SFC integration requires a workaround when used with the current NSH OVS implementation as described in VTEP Workaround for OpenStack Instantiated VMs.
- The DLUX integration is considered an experimental feature. The feature works well but has not been extensively tested.
- Full ODL OVSDB L3 functionality requires a minimum OVS version of 2.3.2. The version is required for ARP responder flows in table 20.
- Stateful Security Groups support using conntrack requires a minimum OVS version of 2.5. Stateless Security Groups without conntrack is supported from OVS 2.3.2 and later.
ODL OVSDB L3
The L3 functionality is disabled by default. To enable the L3 functionality add ovsdb.l3.fwd.enabled=yes to the etc/custom.properties file.
Security Groups with Conntrack
Conntrack functionality is disabled by default. To enable the conntrack support add <conntrack-enabled>true</conntrack-enabled> to the etc/opendaylight/karaf/netvirt-impl-default-config.xml file.
Service Function Chaining
Some configuration is required due to application co-existence for the OpenFlow programming. The SFC project programs flows for the SFC overlay and NetVirt programs flows for the tenant overlay. Coexistence is achieved by each application owning a unique set of tables and providing a simple handoff between the tables.
First configure NetVirt to use table 1 as it's starting table:
http://localhost:8181/restconf/config/netvirt-providers-config:netvirt-providers-config
{
"netvirt-providers-config": {
"table-offset": 1
}
}
Next configure SFC to start at table 150 and configure the table handoff. The configuration starts SFC at table 150 and sets the handoff to table 11 which is the NetVirt SFC classification table.
http://localhost:8181/restconf/config/sfc-of-renderer:sfc-of-renderer-config
{
"sfc-of-renderer-config": {
"sfc-of-app-egress-table-offset": 11,
"sfc-of-table-offset": 150
}
}
Known Bugs
Bug 5351 - Security group connection tracking flows are not getting inserted in OVS https://bugs.opendaylight.org/show_bug.cgi?id=5351 The solution was tested against OVS 2.4.9 and pre-release patches. There has been a change in the connection tracking state bit values in the official OVS 2.5 release. The workaround is to use the OVS 2.4.9 with pre-release patches or to use a later ODL build with the current fix: https://git.opendaylight.org/gerrit/#/c/34655/.
