There are some descriptions in dpdk-16.11\doc\guides\sample_app_ug\vhost.rst, "The sample application performs simple packet switching between virtual machines based on Media Access Control (MAC) address or Virtual Local Area Network (VLAN) tag." So, we want to use vhost-switch between two VMs, one work as server and another as client. We runned the vhost-switch sample in a VM with three virtio ports. First, we binded one virtio port to igb_uio. Then we runned the command "./vhost-switch -c f -n 4 --socket-mem 1024 -- --socket-file /tmp/sock0 C-vm2vm 1 C-dequeue-zero-copy" And then error occured. We found that the 'dev_info.max_vmdq_pools' of the virtio port was 0, and division by zero error occured at the statement 'queues_per_pool = dev_info.vmdq_queue_num / dev_info.max_vmdq_pools;' We fixed this by assigning 'queues_per_pool' to 0 if 'dev_info.max_vmdq_pools' was 0, but there were still other errors when running vhost-switch. After we fixed all the errors while running vhost-switch as server, we didn't know how to run the vhost-switch as client in another VM, how could the client get the socket, the netdev and the virtio port that the server vhost-switch created? So, we doubted whether we use the vhost-switch in a wrong way. Could you please give us some advice that how to use the vhost-switch between two or more VMs? Anybody who can help us with this? &槅bbץrsn9m5jrjybX\d^qyikNץr;{^&~5ߍw]4o'ivJ+,+a#>'{ 6u~zivJ+;۰sm5N]4DyǢ_ɠkM9\mtm=V&t7ץrDH۠sm5mytMKur+s
