That's a limitation of the library, and one that we want to fix. Note also that Daniele has proposed a change to allow -enabling- dpdk after startup. I'm currently reviewing that series. > 2. sometimes dpdk fails to init and aborts process because of inappropriate > configuration. Yep. There's ongoing work in dpdk upstream to rectify this situation, though (I think?) > 3. dpdk lib crash bug. I don't think bugs aren an argument in this case. We find them and fix them, that's that.

If you think it's a worthwhile effort, go ahead and submit patches. It's easy to dismiss an idea out-of-hand if it's just an idea. If you have code that can provide this feature, and submit it, it will be looked at. I haven't thought of any such benefits. I could be wrong. -Aaron _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
