How to connect MTCP to a DPDK vhost port? #290

Closed sarsanaee closed 3 years ago

sarsanaee commented 4 years ago

Hi,

I want to have my MTCP sample application connected to a vhost port. However, I cannot figure out where should I config this. Should I modify the config file in the app directory? At the very end, I would like my MTCP application to use the vhost port which is actually created by my vswitch before.

Specifically, I'd like to use --vdev parameter for typical DPDK applications for the MTCP sample application.

Thanks, Alireza

do you mean dpdkvhostuser ports from http://docs.openvswitch.org/en/latest/howto/dpdk/ ?

I believe something like: testpmd -l 4-5 -n 4 --socket-mem 512 --no-pci --file-prefix=virtio --vdev=net_virtio_user0,path=,queues=2,server=1 ...
