Hi All, First time mailing here. I have installed on a CentOS 7.0 KVM (with DPDK and OVS) one Deep Packet Inspection VM. I have one channel and some virtual traffic generator. The traffic is lost between dpdk vhostuser and the DPI VM. The setup is attached. Any suggestions or ideas? Regarding the OVS+DPDK configuration, the following configuration is already made: - SELINUX is disabled - QEMU

Hello Tinc guys, I was wondering if somebody has had the intend to develop a tinc version using DPDK and KNI type interface to see the increase in term of speed by running everything in userland? Do you think it may be something interesting? I see some of my use cases where it could be really fun to have TINC VPN running under  DPDK.... Thank you for your feedback. Olivier T
