emmericp / MoonGen

MoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 Gbit/s connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet. Multi-core support allows for even higher rates. It also features precise and accurate timestamping and rate control.

issue while building moongen #306

Closed rohit172001-eng closed 3 years ago

rohit172001-eng commented 3 years ago

In spite of manually binding interfaces to dpdk using dpdk-devbind.py

Still I'm stuck with below error

emmericp commented 3 years ago

I think the script just tells you this error even if there are already nics bound, so ignore that

rohit172001-eng commented 3 years ago

Thank you sir, can you also please help me up with these queries 1) Do we need external adapters to run dpdk in virtual machine or in my local machine. image 2) In spite of having supported adapters I'm getting the following error, I've also successfully binded the NICs, but showing valid port array as 0. image
