Also, the weird thing is, testpmd application runs in the container using lxc-execute. Lxc-execute runs the app inside container. It works, see below: =20 root@anjali:/dpdk/x86_64-default-linuxapp-gcc/app# lxc-execute -n foo -- ./testpmd -c f -n 4 -- -i lxc: call to cgmanager_move_pid_abs_sync(cpuset) failed: Escape request from different namespace requires a proxy rte_eal_init : 859=20 opt : 99=20 opt : 110=20 EAL: Using free_hugepages EAL: path /sys/kernel/mm/hugepages/hugepages-2048kB/free_hugepages EAL: No of hugepages is 2048 rte_eal_init : 884=20 EAL: No of hugepages is 0 EAL: No of hugepages is 1 EAL: No of hugepages is 2 EAL: No of hugepages is 3 EAL: Setting up hugepage memory...
