...downgrade to. TL;DR: My container is configured to use "br0" for its networking. "br0" exists totally inside my linux server - it is NOT bound to any physical NIC. "br0" is used for most of my QEMU and LXC VMs. libvirt is reporting that it cannot find device "veth1". All of my Gentoo packages are up-to-date. Digging through my logs (/var/log/libvirt/libvirt.log), I see that I last successfully booted this LXC container on 2013-07-22, with libvirt reporting version "1.1.0".

I have a new x3655 IBM and whenever the /etc/xen/scripts/network-bridge script starts, the ethernet would no longer work. This post isn''t about the cause, but the fix. I did a lot of tcpdumps and Googling, but I''ll spare you that. All they do is prove that yes, there is an issue. :) I tried Debian 4.0 i386/amd64 and Ubuntu 7.04 Server i386/amd64 and they all exhibit the

Using the same pktgen script (i.e with clone=0) I see that a veth-->bridge-->veth configuration gives about 400K PPS forwarding performance where

Hello you all out there Does anybody know the definite guide to create a dummy ethernet device? So, what I want to have is an ethernet device, without a physical link, or so called a dummy device. My goal is to have apache with mod_proxy and balancer running on peth0 in dom0. Apache is spreading my connection to the backend domU''s, where the webservices are running. The connection

Hi, I am using Xen 4.1.1 with Linux 3.0.1 kernel. Previously (Xen 3.4.4 and linux kernel 2.6.18) Xen by default created veth0 <--> vif0.0 pair in dom0. With Xen 4.1.1 these pairs are missing in dom0. Using command ''ip link add type veth'' I can create veth0 and veth1 but vif0.0 is still missing in dom0. (When new domU created I can see vif1.x created) Could you please help me with understanding following things 1) Is veth is replaced by something? and if yes what is it? 2) How to create veth0 <--> vif0.0 pairs? Or how to create vif0.x interfaces? 3) In wh...

Hello everyone, I have been able to get windows xp to run under a virtual machine, but i cannot get any network access. My desktop is connected to a university network, and we are only given 1 ip address. so i understand i have to use routing instead of bridging, right? i have commented the two lines for bridge and enabled routing in /etc/xen/xend-config.sxp next i inserted a line: vif

I have interfaces veth1 to veth7, but I don''t have any veth0, so if I run the same command with parameter vifnum=1 (for example) it works, because it uses veth1 instead of veth0 and add it to the new bridge (although it seems that this is not really necessary, because if I remove veth? from the bridge, networking...

Is there anyone have a domU with routed networking functioning correctly and willing to share their configuration file with me? I must be doing something wrong, but I just can''t see what it is. Comparing with a known functioning configuration would be very helpful. Thanks, James _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com
