Hello all, I spent quite some time now to find out where and what makes virtio-net networking between guests such a lame duck currently in setups with both host and guest being openSUSE with several kernel versions. What I found out was you have to use kernel 3.9 to gain the performance one would expect - but only for single cpu guests. Multi-cpu guest setups are still quite bad. So I want to ask if someone can implement virtio-net queues in a way that the number of queues adapts to the number of cpus for the guest (or make it completely configurable). This would allow cpu affinity for the queue and hopefully bring performance up to the level single cpus have. It seems context switching lets it crawl currently. Any supporters for this idea?
