[Lxc-users] lxc-execute: failed to move 'eth2' to the container : Invalid argument

[lhffjzh]

Hi Friends,

I am investigate lxc now, and I hope to configure a physical NIC(network) into a linux container, as the template "lxc-phys.conf" which in downloaded package, but I got a error "lxc-execute: failed to move 'eth2' to the container : Invalid argument" when I executed command by "lxc-execute", could anyone help me for this?

The OS is CentOS6.3 on my PC, there is a NIC "eth2" plugged on it, and I create a configuration file "./lxc.cfg" for starting physical NIC/network in LXC,  but it complain following error message.
