Yep, these are all challenges. If you have some really specific questions, or things you truly think can't be done, please speak up. But, I really don't see any show stoppers in your list. We also plan to do this incrementally. The first consumers are likely to be dumb, simple HPC apps that don't have real hardware like audio or video. Eventually, we'll get to real hardware like infiniband (ugh) or audio. Eventually. (Actually futexes aren't that bad because they don't keep state in-kernel) -- Dave _______________________________________________ Containers mailing list [EMAIL PROTECTED] https://lists.linux-foundation.org/mailman/listinfo/containers _______________________________________________ Devel mailing list Devel@openvz.org https://openvz.org/mailman/listinfo/devel
