Hello all, I would like to introduce my new project and see if there are people on this list who would like to meet up at KVM Summit this week and give me some feedback. I have a new project called Snabb Switch and it's an open source ethernet switch for hypervisors. I'm aiming for a specific point in the design space: firmware-style code, tight integration with hypervisors and NICs, minimal interaction with the host kernel. Like the Linux bridge or Open vSwitch but running in user-space and nevertheless aims to be the most efficient. I'm extremely interested in getting a complete mental model of KVM networking, and especially to understand all the overhead associated with shipping data from one VM to another. The copies between userspace, kernel space, hypervisor, and so on. I have made some babysteps in KVM hacking with an experiment to backend ethernet ports with shared memory (via mmap() and /dev/shm on the host). I don't know yet how far this is away from a sensible solution. https://github.com/SnabbCo/QEMU/compare/master...shm If you know about this stuff then I would love to chat with you in Barcelona so please contact me off-list. My project url is http://www.github.com/SnabbCo/snabbswitch and I'll be wearing a t-shirt with the Snabb Tiger logo on it :-). Hope to meet some of you in the next few days :) -Luke -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
