Subject OVS integration broken in 4.2 & master
Date Wed, 30 Oct 2013 07:11:15 GMT
OVS integration for GRE overlay tunnels is currently broken in both master and 4.2. Till 4.1,
Network Manager will loop through all the network elements for NIC prepare and release so,
OVS network element had chance to participate in the NIC prepare/release operations. This
behaviour in network orchestrator is changed to loop through only network elements that are
service providers for the network which is right way to do, but OVS network element is not
called due to this. I am planning to fix it by making Ovs network element as service provider
for 'Connectivity' service. This is in consistence with design of other SDN controllers integrated
in CS. So, to use GRE isolation, additional step is required to create a network offering
with 'Ovs' as connectivity service provider. Any concerns with this approach?
