Hello. I am trying to build VM to VM scheme using ovs (git branch-2.4) and DPDK 2.0.0.
I start ovs-vswitchd like this. # ovs-vswitchd --dpdk -cuse_dev_name my-vhost-net -c 0x401 -n 4 --socket-mem 1024,1024 -- unix:$DB_SOCK --pidfile --detach and for increase pmd threads, I use following command. (This system has 2 numa nodes and each node has 10 cores.) # ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=401 but pmd threads are created only on numa node 0. pmd threads are not created on numa node 1. So. I test bandwidth rate VM to VM. VM1, VM2 are on numa node 0 VM3, VM4 are on numa node 1 bandwidth between VM1 to VM2 is about 10Gbps. but bandwidth between VM3 to VM4 is about 6Gbps. I think that pmd threads are created on numa node 1, bandwidth between VM3 to VM4 is up to 10Gbps. Why does pmd threads use only numa node 0? How can I use pmd threads on all numa nodes? Thanks, Cha.
