OpenVZ Remove Venet

Venet is a network device created by default when OpenVZ creates container, and venet does not need to exist after bridging, and you will find that you cannot set a default gateway when creating container, or the gateway is missing after restarting.

The Official chart lists the differences between Veth and Venet.
