Hi Avi, Some links to figures below.
BTW Dropping the dpdk list - I'm not sure how ovs community feels about cross posting. Please feel free to re-instate.

[[BO'M]] Are you you rolling your own solution using xpd/bpf directly or using something like Cilium project? If you could share some details on your use-case and current solution strategy/options that would be really interesting. > > I heard that a vhostuser interface for containers is 'in-working' stage. > Can anyone assist with the performance numbers and the status of this vhost- > user for containers ? > [[BO'M]] There is already dpdkvhostuser(client) interface types in OvS-DPDK which provide virtio backends to allow VMs to connect to OvS-DPDK. Maybe you mean virtio-user which is covered in the paper above? And which was introduced just last year. > Best Regards > Avi _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
