Yes, Contrail with DPDK supports unmodified guests. However, the pps performance is similar to what is seen with kernel mode vrouter if the guest does not use a DPDK application.

Does this support unmodified guests similar to OVS-DPDK? In other words, in the case of unmodified guests, an application running on the VM need not be re-written using the DPDK API to benefit from DPDK acceleration of the vRouter, though the magnitude of the performance enhancement may be limited. Am I correct? I have come across test results with the DPDK accelerated vRouter reported on the OpenContrail web site which report ~500 pps with the Kernel vRouter, and ~4M pps with a native DPDK application. Is any information available on the packet processing capacity for unmodified guests using DPDK enhanced vRouter? Appreciate the information. Thanks, Mo
