similar to: centos with qemu and kqemu

I have been asking on the qemu list how to get bridge network mode working under centos 4... To no avail. The following script is what I have tried as my /etc/qemu-ifup. It supposedly worked for fedora. #!/bin/sh # # qemu_up # # script to bring up the tun device in QEMU in bridged mode # # This script bridges eth0 and tap0. First take eth0 down, then bring it up with IP 0.0.0.0 # /sbin/ifdown

Hello, I have been using the bridging facilities provided by Linux (vanilla 2.6.7 SMP with UML skas host patch applied) to bridge a regular physical ethernet network (on interface eth0) with a virtual network (on interface tap0, cf uml_switch, http://user-mode-linux.sourceforge.net/networking.html). A couple of virtual machines (run using user-mode linux, a tool that enables you to run linux

Hi all, This is my first post to this list. I hope someone can help me, I have been getting grey hairs trying to make this work! I have a bridge setup on a debian sarge box. The bridge is called br0 and sits between my cable modem and a non-name brand router/switch: [cable modem]----[eth1]---[br0]----[eth2]-----[no-name brand router] I have squid setup on the linux box and it works, I have

Hi, we're running the standard linux bridge setup (redundant bridge) for 5 years now. So first of all, thanks to everyone involved for implementing the bridging feature in Linux. Now I'm trying to bridge hosts connected to VLAN'ed Cisco switches using linux bridge. I'm testing the following setup (Kernel 2.6.19, bridge-utils 1.2 on both bridges)

Hello, I'm having a problem getting two (working) NICs enslaved to a bridge to both work in the bridge. The setup is just for testing and looks like this: (NETWORK)-------|bridge|---------|test PC| I'm building a bridge from an old Dell Optiplex GX1 desktop. Using kernel-2.6.9-gentoo-r4, with bridging and ebtables compiled into the kernel; the two PCI NICs are Intel, and the e100

I am using the madwifi driver with the patch to allow changing of the MAC address and I have two other ethernet interfaces plus a pppoe interface. My outbound connection is ppp0. I have ath0, eth1, eth2 for internal interfaces. I have added these three interfaces to br0. Once the traffic leaves the linux router, it gets NAT'd and goes out through ppp0. All traffic on all segments works

any comments? if nothing else, is there any way to atomically setup bridge? not on list, please cc. ---------- Forwarded message ---------- Date: Wed, 12 Jan 2005 21:08:15 -0000 From: Ian Pratt <m+Ian.Pratt@cl.cam.ac.uk> To: Adam Sulmicki <adam@cfar.umd.edu>, xen-devel@lists.sourceforge.net Subject: RE: [Xen-devel] nfsroot and brige > hello, > it seems like a catch-22 to

Hi, I am a beginner of bridge. I have a problem of using Fedora Core 2 to make a simple bridge. Here is my setup: The bridge computer is installed with Fedore Core 2 (with the SE Linux patch). As I know that kernel 2.6.5 is already support bridging by default, so I didn't recompile the kernel. Then I installed bridge-utils-0.9.6-1.i386. And no additional configuration is made. After

Hi, What is the easiest way to bridge between two user-space processes that talk directly to Ethernet interfaces? I have two applications that write/read Ethernet frames to/from Linux Ethernet ports (e.g. eth0). The applications can successfully talk to each other when they run on two machines connected over Ethernet. I would like to be able to test them on a single machine without employing

Hi all, I created a two node cluster that manages virtual machines with two servers connected via a cross cable on the network 10.0.0.0/24. I want that machines that runs on different servers in the network 172.16.0.0/24 can see all the others. To make this possible I've configured a vlan on each server: ... ... 5: eth1.111 at eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc

Dear CentOS, I think i found a "bug" in the /etc/sysconfig/network-scripts/ifup-eth script of CentOS 5.2. i can post the my changed ifup-eth script if you want. Am I the first one with this problem? Situation: - eth2 and eth3 should be in bond1 interface - bond1 should be an interface of bridge named "iscsi" the problem is that the brctl addif command in ifup-eth gets

tags 671018 +patch thanks This issue has been fixed upstream for 4.2 by using the same hotplug scripts for tap devices as for vif devices rather than using a special qemu-ifup script. I don't think this is an appropriate thing to backport to 4.1 for wheezy so therefore I think the right fix is as Pierre suggests to set the MAC address in the qemu-ifup script. In terms of a patch to the

I've been playing around with qemu and wanted to make the guest OS instance visible on my network. This meant getting bridging and tun/tap working. After getting things working by pasting command from the CentOS wiki article plus adding a few enhancements, I decided to capture the process in a shell script that would be suitable for a user in the sudoers file to fire off. Not sure why

<I apologize if this arrives twice... I sent it first from an non-subscribed address, don't know if that'll get to the list or not --JJ> Hi folks, I have an implementation question regarding bridging on a linux box between a catalyst trunk port and a cisco 26something w/802.1q subinterfaces. So right now, there's no vlan trunking going on on the link my bridging firewall sits

Hello people, first of all this is my first mail and I am new to Xen so be nice with me :-) OK, I installed a Centos 5.5 in a system. Used yum groupinstall "Virtualization" to install anything related to Xen. Those packages installed:

re can somebody tell me what am I doing wrong (at this late night hour), because vlan are not getting bridged at all. ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 ifconfig br0 up vconfig add br0 X vconfig add br0 Y X = vlan-ID (example: 222) Y = vlan ID (example: 223) # brctl show bridge name bridge

Package: xen-utils-common Version: 4.0.0-1 Severity: important Tags: patch --- Please enter the report below this line. --- when you use "hardware" virtual machine (with qemu) with xen configured for bridging the network script treates a tap interface and then /etc/xen/scripts/qemu-ifup adds it to the bridge. That would be ok but tap interfaces have a random mac address and the bridge
