OpenVZ container networking trouble

[RRJ]

Hello,
First of all - proxmox is a very nice v. system, thank you
now about the problem:
i've installed proxmox without any problems, downloaded the karmic 9.10 ubuntu container from openvz site, installed it and run. but when i restart the container, after restart there is no network
ifconfig says nothing.
i have to bring every interface in the container manually:
ifconfig lo up
ifconfig venet0 up
ifconfig venet0:0 up

here is config from container:
root@cacti:~# cat /etc/network/interfaces
# This configuration file is auto-generated.
# WARNING: Do not edit this file, your changes will be lost.
# Please create/edit /etc/network/interfaces.head and /etc/network/interfaces.tail instead,
# their contents will be inserted at the beginning and at the end
# of this file, respectively.


auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
broadcast 127.255.255.255
up ip route replace 127.0.0.0/8 dev lo


# Auto generated venet0 interface
auto venet0
iface venet0 inet static
address 127.0.0.1
netmask 255.255.255.255
broadcast 0.0.0.0
up route add -net 192.0.2.1 netmask 255.255.255.255 dev venet0
up route add default gw 192.0.2.1
auto venet0:0
iface venet0:0 inet static
address 192.168.250.219
netmask 255.255.255.255
broadcast 0.0.0.0

and host

sisemon:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
address 192.168.250.220
netmask 255.255.255.0
gateway 192.168.250.1
bridge_ports eth0
bridge_stp off
bridge_fd 0

Hi,
i have not much experience with openvz. But look at a VM based on a container-template from proxmox - they works for we without trouble.

proxmox doesnt have 9.10 images.

so any1 to help me? got in trouble. trying to use proxmox on production, but such problem could make me switch to something else..

To all of those, who will face same problem:
just remove the networking from startup
#update-rc.d -f networking remove
and then get it back again
# update-rc.d networking defaults
did the trick for me, now network starts on container start.

While it does work, I am not sure that RRJ's fix is a correct way to handle this problem...

Been playing around with this on test VMs - it seems that the problem starts happening after "apt-get upgrade" installs ifupdown 0.6.8ubuntu21.2 (which is an update from 0.6.8ubuntu21) - the changelog for it doesn't really give a clear further clue on what might have changed to break this ;/

This blog article + script seems to work and solve the issues with init: http://blog.bodhizazen.net/linux/openvz-ubuntu-9-10-templates/
