Re: [dpdk-dev] [README]:Running DPDK in a LXC-based Container

Hi Alejandro,

Thanks for the response. I tried the --file-prefix option.. But its the
same issue.. :( Looks like the --file-prefix option only determines the
name of the pages to be created under /mnt/huge/.

I will try the --huge-dir option as well and see if I can do anything with
it or not...

Thanks and Regards,
Pushpasis
