similar to: two bridges share the same bridge ID.

Hello all, I have a Xen server with 6 network interfaces, I want a bridge on all of them. I use a personal network script like this : #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@"

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

Has anyone ran into this issue before? 2 physical nics: eth0 hooked up to 10.175.8.0/21 eth1 hooked up to 10.150.8.0/24 Ifconfig -a looks like this: [root@mgixen1 ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:19:B9:F2:1B:C3 inet addr:10.175.8.158 Bcast:10.175.15.255 Mask:255.255.248.0 inet6 addr: fe80::219:b9ff:fef2:1bc3/64 Scope:Link UP

CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere. I want to keep the

Hi! I''m not new to Xen but I''m new to this list. I''m having a truely bizarre problem with Xen bridged networking at the moment. This is a new install, on RHEL4. The symptom is that any domU set up simply fails to talk to anything else. It''s there, and running, and it has an ethernet device, but there''s never any response. After digging through the

Hi *.*, This is a continuation on the 2 NICs thread after some more testing. Just to remember my goal. --------------------------- I want to create a domU with 2 virtual NICS. One of them will contact the outside world, the other one will contact a VPN. No reason in concrete for choosing the bridging protocol, only because its the default one. I installed the dom0 with the 2 NICs active, with

Hey All I''m Using Xen 3.0.3-105 on CentOS 5.5. It Has to Nics: eth0 - Internet eth1 - Internal Lan ( where Dhcp , DNs , Cobbler - Kick Start Server Resides ) I''ve Set xend-config.xsp to create xenbr1 on eth1 and it looks well So Guest May Get Access TO ALl Resources via the Bridge. brctl show bridge name bridge id STP enabled interfaces xenbr1

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

Hi, I have a PC with 3 ethernet interfaces. I am trying to a) assign 2 ethernet interfaces exclusively to one domU by using the late binding method and b) to use a bridge between the third interface and dom0 (that works fine). The goal is to not to have to use bridges for the exclusively assigned interfaces. Is it possible? (If not, no need to read the rest) The problem I have is that I

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

Hi Folks: I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0 setup running xen 3.4.3 and have been struggling to fix it for some time. I could not find anything by googling or searching through this list but that is probably because I couldn''t figure out the correct search terms. After I configure my bridges the command "system network restart" fails for eth1

Hi @all, I tried to setup xen 3.3 on centos 5 Update 2. I used the following packages: http://bderzhavets.blogspot.com/2008/08/install-xen-3.html The server has 4 physical network interfaces and i want to use them all. eth0 => only for host (configured with static ip) eth1 => first vm (configured with static ip) eth2 => second vm (configured with static ip) eth3 => all other vm

Here is the situation. I have a xen system with 2 drives setup in a RAID1. I pulled one drive and put it into an identical server. Now, when I boot up the new server, peth1 is not created. [root@dom0 ~]# ifconfig | grep Link eth1 Link encap:Ethernet HWaddr 00:14:38:A7:55:C2 inet6 addr: fe80::214:38ff:fea7:55c2/64 Scope:Link lo Link encap:Local Loopback vif1.0 Link

Hello everyone. I just installed Xen 3.0.3 in a debian etch box. Linux server1.example.com 2.6.18-6-xen-686 #1 This server1 has two real nic (eth0 with real MAC 00:13:72:57:7B:AE and eth1 with real MAC00:13:72:57:7B:AF).

Hello, We have a machine (Debian Etch, Xen from Debian repositories, etc.) with two NICs: one for LAN (192.168.0.0/24) and another one with public IP address. After enable Bridging (in /etc/xen/xend-config.sxp): (network-script ''network-bridge netdev=eth0'') (vif-script vif-bridge) # eth0 is the LAN NIC I have eth0, peth0, vif0.1 (I guess that it''s usual for you) and

Hi, I would like to ask concerning problems after installing xen 3.3 on Centos 5.2 I use 2.6.18.8-xen (xen3.3.1 testing - installing with mercurial). After done with make world and make install, I did mkinitrd and placing it in /boot changing the grub and reboot.. succeded I do not install libvirt and the domUs from the previous xen 3.0 (built-in Centos 5.2) are NOT able to start : [root@wing

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:

Hi everyone, I have looked through the list archives and seen a few posts about jumbo frame support, but there is no definitive answer on whether or not it has been tested or is working for anyone. I tried using an MTU of 9000 in a domU and encountered some very interesting and not-so-great results. My machines used in this test are: * NFS (physical) * dom0 (physical) * domU (virtual)

Hello all, I have been running xen for a while now with two interfaces: dummy0 for host only communication, and eth0 for the outside network. my script looks like this: (/etc/xen/scripts/network-bridge-more) ------------------------------------------------------------------ #! /bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=dummy0

Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services
