I create the veth1.0 device in the Hardware Node, but no eth0 is seen int the ConTainer.
Networking scenario: br0 is a bridge in HN with eth0 and eth1 included. eth0 is the only physical ethernet plugged.

Previus ifconfig in HN:

The change:

vzctl set 1001 --netif_add eth0,,veth1.0,,br0 --save

Next ifconfig in HN (seems to be right):

Tried to restart the container (vzctl stop 1001 ; vzctl start 1001), but the result is the same when entering to container (vzctl enter 1001)

Software:
- Hardware Node with Ubuntu 10.04, recompiled kernel 2.6.32 with dzhanibekov.1 patch
- ConTainer (VEID=1) created with Ubuntu 10.04 precreated template
- vzctl version 3.0.23

(The final target is to set-up a DHCP server into a container)

Ok, I see it was down in container (ifconfig -a):

eth0      Link encap:Ethernet  HWaddr 00:18:51:9b:10:7a

          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1

Now I've removed previous IP configuration with this in hardware node:

vzctl set control --ipdel all --save

And replaced whole content of container's /etc/network/interfaces by:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
        address 192.168.1.1
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.252

And after this I obtain this with ifconfig -a :

eth0      Link encap:Ethernet  HWaddr 00:18:51:9b:10:7a  
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

But there is no communication from container:

Nor from a hardware desktop to container:
