Talk:Virtual Ethernet device

Under Common Configurations -> Simple configuration -> Configure devices in VE0, the example shows

[host-node]# echo 1 > /proc/sys/net/ipv4/conf/eth0/forwarding
[host-node]# echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp

being run on the host node, VE0. I don't think this can be correct, because eth0 exists in VE 101, not VE0. —The preceding unsigned comment was added by Andrex (talk • contribs) 01:11, 15 July 2006.

This is correct, because we need to enable forwarding on both network interfaces in VE0 (host-node eth0 and veth101.0) to allow the network packets on one network interface (host-node eth0) to be forwarded to another network interface (veth101.0). The same thing with proxy ARP, we need to enable it on host-node eth0 and veth101.0 network interfaces. --Major 08:42, 17 July 2006 (EDT)

Multiple persistent Veth interfaces

The script for making a persistent bridge get added to a particular host-bridge on startup VPS/VE, doesn't seem to account for having multiple bridges. I have a bridge to a private lan for administrative functions and a bridge to the public network for inbound connections for services. How might one ensure that the vethVEID.x's are hooked up to the bridges on the host every time the VE is started? --Btrotter 05:34, 17 March 2008 (EDT)

Please take a look at Using private IPs for Hardware Nodes and http://vireso.blogspot.com/2008/02/2-veth-with-2-brindges-on-openvz-at.html. There you will find scripts which will help you to manage 2 bridges, and you can simply extend this script to use more then 2 bridges. --Major 15:59, 27 March 2008 (MSK)

Making a bridged veth-device persistent

Is this also obsolete, like the section I just deleted? Mrjcleaver 13:35, 31 May 2008 (EDT)

Please leave this in for now! I just needed it today for setup on a Debian HN.
Also I noted that a crucial word/reference at the end of the following sentence is missing: "4. Of course, the CT's operating system will need to have ." Could someone with wiki-knowledge please restore this (if it was ever known)? Laboa 22:50, 12. Oct 2008 (CEST)

Configure devices in CT0

These devices under /proc didn't exist for me, but I left them in case they are still needed, even with the new vzctl. Mrjcleaver 13:59, 31 May 2008 (EDT)

Creating veth without OpenVZ

How to create veth devices pair without of OpenVZ? I want something like

modprobe veth
ifconfig veth0 192.168.0.1
ifconfig veth1 192.168.0.2
