[Users] Giving a container access to the dhcp server

[Daniel Thielking]

Thanks for the link below, but I now about veth and venet.
I have read this article 
"https://openvz.org/Virtual_Ethernet_device#Independent_Virtual_Ethernet_communication_through_the_bridge" 
but it didn't helped me.

What I tried:

I created a new Container:

    vzctl create 101 --ostemplate=...

I set a veth device:

    vzctl set 101 --netif_add eth0,"specified MAC",veth101.0 --save

I added IP,Mask,Gateway inside the container and tried to ping but 
nothing happend.
Which steps do I forgot? Maybe the bridge and if yes could you give me 
more Information how to setup. But it is important that all other 
containers still have the venet and just on gets a veth.

Thank you
