Re: [dpdk-dev] QoS scheduler example fails to run

["Dumitrescu, Cristian" <cristian.dumitrescu@intel.com>]

Hi Reza,

As your log displays below, you have an error in EAL initialization:

EAL: Error - exiting with code: 1

I suggest you try to dig up the source code to understand which is the line of code triggering this error in your system and why.

Regards,
Cristian
