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" "$@"

Hi, I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These servers have 10 nics (2 onboard and 8 in two 4-port cards) so that every vm can have its own interface. This worked so far with the Xen Version from Etch with a wrapper script wich started 10 bridges at boot time. But now I''ve updated Xen on one of these server to Xen 3.2.0 from backports.org and now the

Hello all, I''m using Red Hat Enterprise Linux 5 (with RH Virtualization) and a Dell Poweredge 2950 with 10 NICs. My virtual operating systems are all RHEL4, and I''ve installed 4 instances. I''m trying to set up the virtual operating systems so that the physical NICs are allocated to certain operating systems. Using the following tutorial:

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've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's. Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are

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

Hi, I am facing issues after upgrading one of the server from rhel5.5. (86_64) to latest rhel5.7 (86_64). The server is under trunk configuraion. I have set the network bridge as follows: #!/bin/bash vconfig set_name_type DEV_PLUS_VID_NO_PAD dir=$(dirname " $0" /etc/xen/scripts/network-bridge $@ vifnum=1 bridge=xenbr2 netdev=bond0.10 /etc/xen/scripts/network-bridge $@

Hi, In one of our xen server, I am using two bonding. bond0 : Is for trunk, where the vlans are attached , port eth0 & eth1 is attached to bond0 bond1 : eth2 & eth3 are attached to bond1, where physical ip has been set . In the /etc/xen/xend-config.sxp, I am using (network-script *multi-network-bridge*) , the

Hi. I have another question, hopefully easier than my last: Do all physical interfaces in dom0 need to have an IP addresse in order to be used as a bridge by guest domains? I thought that the interface would have to merely be "up" but not necessarily have an IP address configured since bridging is done at layer 2. But alas, if I don''t configure an IP address on dom0 the bridge

Hi all, I''m searching for a tutorial how to setup multiple network cards with xen network bridge setup in debian lenny. My problem is, bridges seams only to work if i put an ip adress in dom0 to them.

Hi, we''re running 4 xen servers on our network with multiple network cards. During HighLoad we experince degeneration of inbound network traffic through our loadbalancer. I might found a reason for it, in Dom0 dmesg output looks as follows: [1157421.975910] eth0: received packet with own address as source address [1157421.975957] eth0: received packet with own address as source

Hi! I have a problem with my new Xen setup. I have installed Debian etch with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and 3.0.3-0-4 version xen hypervisor. I''m using four network cards on my system and using three of them as xen bridges and dom0 is using the fourth one only for it''s own. So basicly both of my virtual servers use a network card

Hi all, my Dom0: Debian Unstables with 2.6.16.33 - Xen 3.0.4 my DomU: HVM Windows Server 2003 I have 3 different LAN interfaces in my DomU. If I configure them i can successfully ping into the different networks. My domain-config for these 3 LAN-IF looks like this: vif = [ ''type=ioemu, mac=00:16:3e:62:b3:ae, bridge=xenbr1'', \ ''type=ioemu,

Hello, Where can I find a link (or docs) to *working* network config for xen 4.1.2? My tests (s. below) were not successful. Thank you in advance for any hints.

Hi All, We have a single Centos 5.11 server running a xen hypervisor that went down hard after an extended power outage this weekend. I'm mostly familiar for KVM as that is the majority of what our guests run under and have tried getting up to speed on xen bridging to no avail. The problem is that after the xen server spun back up, the previously defined xen bridges were lost. I've

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

Hey all I''m new to Linux and Virtualizing. I''m trying to dedicate my nic''s to each virtual server. For instance, virt server A would use nic1 and virt server B would use nic2 and so on. I''ve been reading some stuff for this list and to tell you the truth I''m a bit overwhelmed. We are going to run SLES10.1 and Xen. I would appreciate any assistance.

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

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:
