Description Meng Bo 2016-03-29 08:47:57 UTC 
Description of problem:
For now, if configured different network plugins for master and node, both the services will run well. But the created pods will be in mal-function.

If master is configured as multi-tenant, and nodes are configured as subnet, the pods created on nodes will use the flat network.

If master is configured as subnet and nodes are configured as multi-tenant, the pods will not be created due to error fetching VNID.

It is better to avoid these kinds of conditions before the services are running.



Version-Release number of selected component (if applicable):
openshift v1.1.4-314-ge2e226f

How reproducible:
always

Steps to Reproduce:
1.
2.
3.

Actual results:
Node service can be ran if the network plugin has different configuration with master.

Expected results:
Should not start the node service if the network plugin does not match master config.
