Hello everybody, I have an odd problem with iptables using a Xen bridge setup. I don''t know if it would be better to post to netfilter Mailing-List. But I hope someone here know how to solve it. If it''s OT here, please let me know. I''ll try to do a little bit ASCII-Graphics to explain the topo better: _________ ________

This patch adds an ACM hook into the network scripts (/etc/xen/scripts). It adds iptables rules that enforce mandatory access control on network packets exchanged between virtual interfaces. If ACM is active, this patch sets the default FORWARD policy in Dom0 to DROP and adds iptables ACCEPT rules between vifs that belong to domains that are permitted to share (determined by using the

hi fellow XEN-users: I have been trying hard to get this problem fixed, hope I can get some help here. Thanks in advance for your time. I have a typical dom0 + domU XEN setup. after I start xend and network-bridge, I get the default network setup, , peth0 -------- bridge ------------------------------------------------------- |

Hi, If one sets xend to use network-bridge and there are no bridges already present then it seems that xend will clone eth0 to peth0, create xenbr0 and add peth0 and vif0.0 as ports on that bridge. If on the other hand xenbr0 is created in /etc/network/interfaces then xend will not do any of that peth0 stuff, nor will it add vif0.0 to xenbr0, yet (barring some changes in iptables rules) things

Hi all, I am running Xen 3.0.2-2 (taken from XenSource) with Linux kernel 2.6.16 (taken from Debian Sid), I compiled Xen and 2 kernels (dom0 and domU).

Hello, I have problems with installation of my second DomU. I cannot ping it from the outside world and I cannot access outside world from this domain. I see it from Dom0 and my first DomU, same as my second DomU can ping Dom0 and my first DomU. I use xen 3.0.3 on ubuntu 6 LTS. DomU is running on debian. I also network-bridge script in the xend config.

Objet : Xend start and after lose network Hi everybody : My configuration : Dapper 6.06 LTS with all updates Xen 3.0.2.2 My problem : After making ''xend start'', I lose network connections between my server and local network or internet. Nota : domU cas normally access to network I read about a similar problem in the bugtracker (N. 62) but it seems that this is normally

(if this post gets line-feed-mangled please read http://www.dl.reneschmidt.de/shorewallxenpost.txt - that''s an unmangled version, thank you) Hello, first I would like to thank the Mr. Eastep and contributors for this great piece of software and superb documentation. I have a SOHO server (Debian testing) that I''m using for several purposes so I''ve set up a Xen

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to

Package: xen-utils-common Version: 3.2.0-2 Hello We used the script "network-bridge" on our Xen servers based on "etch" (xen-utils-common 3.0.3-0-2) to setup bridge configuration. This script created a bridge "xenbr0", renamed "eth0" to "peth0", renamed "veth0" to "eth0" and added "peth0" and "vif0.0" to

Hello, I have the following Xen 3.0.2-2 related problem: A host system with Centos 4.4 in the dom0, guest systems are Fedora Core 5 (images from jailtime.org) mounted on LVM. Networking on the domUs is not working, Iptables in the guests are not working either. Each Guest system should have at least 1 dedicated public IP assigned to it, but should have the capability to have more than 1

Hello, The basic details of my host and XEN configuration and network configuration all appear below. Whilst I have come this far, a lot of it has been intuitive so I now have plenty of questions. Firstly I would like some help and clarification with regard to ebtables and especially how it works in a Virtualized environment on Novell SUSE 10 SP1 (1) ebtables Installation ebtables was not

So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that connects dom0 and most of the domU to the physical card and the out to the network. Got that figured out no problem, now i want to have a second bridge that runs a local network for all the doms that doesn''t connect to the network. With code I have found used in multiple places I can easily get 2 bridges, and

I''m having trouble getting ingress policing to work on a bridged device. The bridge contains several interfaces: peth0, vif0.0, vif[1-7]0.1, vif[25].1 . (This is under xen, in case the vif''s didn''t give that away, so peth0 is renamed eth0.) The tc rules I have are: tc qdisc del dev peth0 root tc qdisc del dev peth0 ingress handle ffff: tc qdisc add dev peth0 root

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c. I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.

*Hello,* I have installed Xen as Hypervisor with OpenSUSE running in Dom0. I want to use ovswitch (ovs) instead of the bridges that Xen created. In order to do so, I installed ovs in dom0 just like for the plain Linux. Xen has replaced eth0 with peth0, and has created a bridge named eth0. And eth0 is connected peth0 interface , vif2.0 interface (VM), and everything is working fine. Now I delete

Hello Everyone, I have set up a xen server with 10 physical network devices using the bridge mode of XEN. This is because I want to split and separate the network traffic for security reasons. Maybe the best way is to use pci back hide. But I want to understand what is going on here. For all testings I have only activated eth[0-3]. My first tests were successful. I have created a VM using

I''ve just installed Xen on a new CentOS 5.1 system, and I can''t seem to make xenbr0 connect to the network. This system has a single physical network card. Apart from creating a few DomU guests, I have not changed any of the configuration. After running network-bridge, xenbr0 and friends are created, but the address and routing info is not moved.
