Hi,
I am running DPDK application on VM instance (openstack) with multiple cores. It has no PCI passed through Ethernet device. It has only Virtio network devices. I have configured the Receive side scaling (RSS) while initializing Ethernet port. I am sending UDP traffic with 8 different traffic flows (Each flow will have different source IP address). But I find, all the traffics fall into one core. It means hash value which is based on the packet IP addresses the protocol (UDP or TCP) and the ports (5 tuple) are same for all the flows. Can anyone please suggest whether RSS is supported by Virtio network devices or not? Thank you in advance for your time and support. Regards, Chinmaya
