Hi all, I'm working on create a large number of tcp connections on a guest; The environment is on OpenStack: Host (dedicated compute node): OS/Kernel: Ubuntu/3.2 Cpus: 24 Mems: 128GB Guest (alone on the Host): OS/Kernel: Ubuntu/3.2 Cpus: 4 Mems: 32GB Currently a guest can handle about 700 000 established connections, the cpus are not loaded and 12giga of memory are used. I'm working to understand why I can go up... On my host, after several tests with different versions of openvswitch and with linux bridge, It look like the process vhost_net is the only process loaded to 100% and it seems vhost_net cannot use more than 1 cpu. I would like to get more informations about vhost_net and if there is a solution to configure it to use more than 1 cpu? Thanks a lot, s. -- 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
