Re: [affinity-dev] Sample Bundles in the Virtualization Edition


Colin Dixon <ckd@...>
 

For what it's worth, I'm in the process of removing the requirements to configure SimpleFowarding so that it acts as a normal L2 switch across all the ports in the system when there's no configuration.

I'm probably the primary reason that Ed says it should do *something* when it comes up because I've been hammering like crazy on that point for the base edition. I'm not sure it's as critical here that it work immediately out of the box, but making sure that either (a) it does something without configuration when it comes up or (b) we do really good job of explaining what configuration needs to be done and give some useful error if we do nothing.

Does that seem reasonable to people?

In the long run, maybe we should talk about having a NotSoSimpleForwarding bundle that is designed to take in affinity information, virtual networks, etc. and implement them properly rather than having each different solution manage the rules on their own. This would help separate the policy from the actual routes and allow for faster innovation in both.
