Successfully converted kvm to openvz - need help

[kumarullal]

Hi I successfully managed to converted the kvm image of asterisk pbx based on Centos into openvz container image by following http://wiki.openvz.org/Physical_to_container

I also have downloaded the openvz image of mgate (proxmox mail gateway)

I compared the proxmox mail gateway, mgate container (105) conf file located in /etc/vz/conf/105.conf with
the one I created located at /etc/vz/conf/211.conf

I made some adjustments in my newly created conf file according to what was set in 105.
When I started the container 211, I got the beautiful root prompt on CLI.
The only problem I found was that the network was not showing up.
when I tried run the ifconfig eth0. It told me that could not find the eth device.
I have added an attachament of the screenshot in this post.

Here is the conf file I have for my container 211

OpenVZ has 2 different network modes - venet and veth. If you need an eth0 device you need to use veth (bridged) mode.

Thanks for your reply.
Managed to do this by this command
vzctl set 101 --netif_add eth0 --save

The network error stopped but there are number of other error.
First of all I want to understand, since KVM image is a Virtual machine image. So when I import the machin using rsysc,
Why should we exclude the dev (Devices), proc and temp directory from the KVM image.
the rsync command I used
rsync -arvpz --numeric-ids --exclude dev --exclude proc --exclude tmp
-e "ssh -l root@192.168.0.100" root@192.168.0.100:/ /vz/private/211/
Secondly Why should we disable udev.
Because I am getting number of errors pertaining to tty0 not found, tty9 not found.
These are present in the original KVM images's /dev directory.
Number of services are failing to start.
I have spent more than 4 days just trying to figure this out with various permutations and combinations
Your help will be greatly appreciated.
