Setting up the network (Help! Can't get internet in containers)


What I'm Building:


I am using Proxmox to build a Virtual Server Environment with KVN and OpenVZ.


- I have Proxmox Virual Environment Installed with KVN and OpenVZ.
- I can create a virtual container.


My Problem:


- Getting containers to connect to the internet
- Deciding the best solution on how to enable each network with it's own IP address


I have a dedicated server that is being hosted by my provider and it is virtualization capable; however, I do not have experience beyond installing and managing lamp servers on a single IP address.


They have issued to me what appears to be 2 ethernet cards.
I have multiple ip addresses on one NIC (Eth0) that has a vlan with eth0:0, eth0:1, eth0:2, etc.


What is the best way to set up the network to point to my array of IP addresses to different containers or hardware virtualizations?


What should my files show?

Alright. I can gain internet via venet by setting the ip address to 192.16.1.x ; however, this doesn't allow me to set an ip address for each container.

I'm guessing I'll neet to use veth, but I'm still unsure how to go about configuring veth with a vlan of ipaddresses.
