Hi Ilya, Thanks for the help. Providing a different option for queues worked for the physical interface that is added to OVS. But now we have a different issue. We are running an mTCP application inside the VM. mTCP uses a different RSS hash. I feel because of that the packets are not getting

Hi Ilya, Thanks for your suggestion. We tried pinning the PMD threads to core. But still the issue exists that only single queue is working instead of multiqueue. We tried using 'dpdkvhostuserclient' instead of 'dpdkvhostuser' but we are getting the following error and the VM is not able to

Thanks for the response Ilya. We could get this setup working now. However, we could not get it working when we want to give two queues to the VM interface. We added the queue option when creating the interface on OVS. We also enabled multiqueue in VM XML and gave the interface and set the

Hi. At first you need to look at ovs-vswitchd.log and the log of qemu. There might be some errors. Some thoughts inline. Best regards, Ilya Maximets. > Hi All, > > Our setup is as follows: > > We have two servers which are connected peer to peer over 40G > interfaces. > > On one server we

Hi All, Our setup is as follows: We have two servers which are connected peer to peer over 40G interfaces. On one server we have setup OVS and added the physical 40G interface as a DPDK interface to the ovs bridge. We created another dpdkvhostuser interface for the VM. We added this
