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...

I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out. Any guidance in this regard would be a great help. These are my System Logs: Mar 28 18:03:04 dpdk-OptiPlex-5040 libvirtd.service: 1529: debug : virCommandRunAsync:2429 : Ab...

The network device model is a userspace API, and DPDK is a userspace application. You can't go breaking userspace even if you don't like the application.

Hi, I was debugging an issue caused by a bad usage of dpdk. That is fixed in the meantime and I'll backport that into our code as well. But along debugging that, I found a potential hang in virtnet_send_command that my case ran into. The following code can become an infinite loop: /* Spin for a response, the kick causes an ioport write, trapping * in...

Hi, I'm having trouble starting a VM with vhostuser interfaces. I have a simple configuration where a VM running Debian has 1 vhostuser interface plugged into an OVS switch where a DPDK interface is already plugged in. $ ovs-vsctl show: Bridge "switch1" Port "switch1" Interface "switch1" type: internal Port "1.switch1" Interface "1.switch1" type: dpdk options: {dpdk-devarg...
