[dpdk-users] running dpdk in lxc-container

[Avi Cohen (A)]

Thanks Ravada
I've already resolve this issue by binding the devices in the host and mount the /dev/uiox/ in the lxc with mknod command
This is described here:  http://dpdk.org/ml/archives/dev/2014-October/006373.html

But when I run my dpdk application I receive this error :
EAL: Cannot open /dev/uio0: Operation not permitted
Btw - I'm running as root
Best regards 
avi
