Re: [dpdk-users] Request an example config for DPDK IP PIPELINE

[Royce Niu <royceniu@gmail.com>]

Dear Jasvinder and Fan,

Thanks for your concerning. I solved the problem by

adding "–smp sockets=1,cores=2"

The correct XML format is

<cpu mode='custom' match='exact'>
    <model fallback='allow'>SandyBridge</model>
    <topology sockets='1' cores='2' threads='1'/>
    <feature policy='require' name='lahf_lm'/>
    <feature policy='require' name='cx16'/>
    <feature policy='require' name='avx'/>
  </cpu>


By the way, if your NIC (virtio) cannot be started, please disable
app_link_up_internal() in init.c

Thanks for Jasvinder for the solutions.

So far, I can use pipeline (l2fwd and firewall) in KVM (Ubuntu 14.04), if
other guys have problem on my config, feel free to contact me;
