We have developed virtio-user + vhost-kernel as the backend. In that scenario, you can add the tap interface into a container network namespace. And there's a vhost kthread to push the data out to user space. And I cannot guarantee the performance as it has diametric model in VM (virtio) - OVS-DPDK (vhost). > I've tested the performance of a container connected to OVS-DPDK via > vdev-af_packet and processed by virtual PMD, and its performance is good > [uses mmap'ed to userspace - zero copy RX/TX ring buffer] > but not good as the performance of a VM connected to OVS-DPDK (@host) > via vhost-user virtio. > Best Regards > avi > > > -----Original Message----- > > From: Tan, Jianfeng [mailto:jianfeng....@intel.com] > > Sent: Monday, 26 June, 2017 6:15 AM > > To: Avi Cohen (A); dpdk-...@lists.01.org; users@dpdk.org > > Subject: RE: VIRTIO for containers > > > > Hi Avi, > > > > > -----Original Message----- > > > From: users [mailto:users-boun...@dpdk.org] On Behalf Of Avi Cohen (A) > > > Sent: Sunday, June 25, 2017 11:13 PM > > > To: dpdk-...@lists.01.org; users@dpdk.org > > > Subject: [dpdk-users] VIRTIO for containers > > > > > > Hello, > > > Does anyone know the status of this project > > > http://dpdk.org/ml/archives/dev/2015-November/027732.html - > > > Implementing a virtio device for containers ? > > > > It has been upstreamed since v16.07.
