Bridged Interface not showing up in CT

Hello,

I have created a bridged interface for my CT (via the proxmox web UI), but that interface does not show up when I start my CT.
I have tried with CentOS 5,6 (x86 and x64), and also with Debian 7, but with no luck.

I see the following message:
Setting CPU units: 1000
Setting CPUs: 1
Configure veth devices: veth101.0
Adding interface veth101.0 to bridge vmbr0 on CT0 for CT101
Container start in progress...

But when I use "vzctl enter 101", and run "ifconfig", I do not see the eth0 interface inside the CT (whereas the veth101.0 interface is properly created on the host).

Here are the logs from /var/log/messages
Nov 24 08:01:30 sd-32691 kernel: CT: 101: started
Nov 24 08:01:31 sd-32691 kernel: device veth101.0 entered promiscuous mode
Nov 24 08:01:31 sd-32691 kernel: vmbr0: port 3(veth101.0) entering forwarding state

and output for pveversion -v

I have been banging my head with this for the whole day, so really any help would be greatly appreciated! :)

Thank you
 
When using a bridge with a container you need to go into the container and configure the network device. In Debian that would be in /etc/network/interfaces. Either create a eth0 as static or dhcp

Thank you for the fast reply!!

I thought that OpenVZ would set up the interface automatically (like it does for venet). I guess I was wrong, and now I feel so stupid for thinking so :D

Are there any specific configurations that I need to write down, or is it just similar to adding any other network interface?
