similar to: second bridge for dual homed machine!

Hi, I''m setting up my first xen machine, and I''m trying to setup two Virtual Machines, each mapped to a physical adapter on a different network. The virtual machine mapped to xen-br0 and eth0 works fine. However, when I bring up a VM with this configuration file: ----------------- name = "test77" kernel = "/boot/vmlinuz-2.6.11.12-xenU" root =

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

[desktop] ----- lan ----eth0 [notebook] eth1 192.168.?.? ` ----- wlan ---- [speedport(hub and router)] -- internet 192.168.2.x So on my laptop I have eth0 beeing lan, eth1 beeing wlan ethernet card. When only using eth0/1 everything is fine. Now I want to be able to use internet from both [desktop] and [notebook]. Typically you set up a bridge with

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

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

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.

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

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. 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 guys, i use xen3.2. how can i manually create the xenbr0 ? which parameters have i to choose for brctl ? thanks, -- Viele Grüße Dominique Holger Schramm | Linux Administrator http://schwarz-weiss.cc/ | Life between PuTTy and reality http://ihr-linuxadmin.eu/ | Commercial Admin Service _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

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

Hello, I have a big problem: Dom0 is centos5.1, domU are centos5.1. My setup is really simple, the only thing is that I give 3 nics to the domU so I use a modified network script (which has worked since january... since fedora 6): " #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 "$dir/network-bridge" "$@" vifnum=1

<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

I have been looking at this problem on and off for a considerable period. Given my lack of knowledge I have been unable to resolve this quickly and in consequence it has been constantly shoved to the background as other issues arise. Here is the situation: I have two dual-homed kvm hosts both running CentOS-6.7 and identically configured. These are connected to the same LAN segment via

Even more puzzling, I reverted back to the old configuration to confirm what I had seen and found that it works in one direction but not the other: i.e. from 192.168.0.110 to 192.168.0.120, but not the other way around. Must be something with my configuration....which I can follow up on. So, thanks again for your help. Richard On 12/3/19 11:36 AM, Richard Achmatowicz wrote: > Laine >

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

Hi Laine What you have suggested sounds eminently reasonable. Thanks for your advice. I'm going to give it a shot and report back.

Hello I have a problem with attaching VMs to a VLAN interface. Here is my setup: I have several physical hosts connected by a physical switch.  Each host has two NICs leading to the switch, which have been combined into a team, team0. Each host a has a bridge br1, which has team0 as a slave. So communication between hosts is based on the IP address of bridge br1 on each host. Up until
