lxc stand for Linux Container.

Now i will start to describe how to create container using this command 


You need to know when lxc installed, it's create file under /etc/lxc/ called default.conf this file should contain your network interface name and you need to add it.
[root@OEL6 ~]# cat /etc/lxc/default.conf
lxc.network.type = veth
lxc.network.link = docker0
lxc.network.flags = upSample output for ifconfig command :
docker0   Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          inet addr:172.17.42.1  Bcast:0.0.0.0  Mask:255.255.0.0
