Packets are processed by the network stack (including OVS) inline on the CPU that the are received by the kernel. This means that on receive the CPU is determined by the NIC's ability to spread traffic around and on transmit by the hypervisor. Creating additional instances of OVS has no effect on what core packets are processed on. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
