In a compute node running contrail vrouter , we see the node losing host connectivity after vrouter kernal module is inserted and the vhost0 is up. We use the script if-vhost0 , which calls vrouter-functions.sh to insert the vrouter kernal module and configure pkt1 and pkt2 interfaces. After debugging we found that the issue is caused when the vrouter-functions.sh changes the rps settings in pkt2 queues. We see this behaviour only in virtualbox. Is this a known issue , also what is the impact if we disable setting of rps in pkt2 Regards, Pramod.V Manager, Reliance Jio Infocomm Ltd
