Hi all, I have one bridge system (used for controlling bandwidth) connected to three different DSL ISP provider. I have the following setup below: - +-------------+ | br0 | | -> eth1 | -> DSL_1 | -> eth2 | +-------------+ | br1 | | -> eth3 | -> DSL_2 | -> eth4 | +-------------+ | br2 | | -> eth5

Hi everybody ! I'll try to explain first what I would like to do with the functionalities of tap and bridge interfaces, qemu, some isos(I used slax(slackware live cd)) and the forwarding mechanisms of the Linux kernel. I'd like to simulate such a network: Internet | (eth0:@public address) * host * | br0 (@192.168.0.254)

hi all, (this events ocurred before my previous mail about the uuid incident) so, I installed a vm host: rhel6 guest: centos6 network: bridge (br0, eth1 as slave) but then, I changed the name of the bridge from br0 to br1 (because br1<->eth1 seems pretty than br0<->eth1) so: - mv /etc/sysconfig/network-scripts/ifcfg-br0 /etc/sysconfig/network-scripts/ifcfg-br1 - edited

Hi, I'm not sure but I think I suffer under the same problem with a bit different setup with squeeze testing and xen 4.0rc5. In fact I'm using bridges in the dom0 and the connections to the domU get lost sporadically. In don't see where's a solution to the problem... Is it now a bug? When it's an iptables bug, where's the corresponding bug in the iptables bugtracker

Hello all, I am new to Linux Ethernet bridging. Let me first start with what I am trying to achieve. Well you see - I am attempting to have 2 main firewall running at the same time - one as a master and the other one as a slave. Yes, I would like to make use of Ethernet bridging in this scenario - as I understand it, all I need are two machines and STP enabled. I am running Debian

I would stop the VM, edit its definition file (that's an XML file) and then start it up. But be careful: After you edit the XML file, you need to execute a command so KVM re-reads that file. I forgot that command, but you can look it up on Google. On Dec 9, 2015 7:52 AM, "Howard Leadmon" <howard at leadmon.net> wrote: > > > Maybe my google-fu is failing me, but I have

Hello Everybody, I have a physical machine with 4 Ethernet cards that I have mapped to 4 bridges. I would like to have each of my KVMs use 2 bridges for NIC bonding. 1. Can I have more than one bridge assign to one KVM? 2. Can I use virt-install to assign a KVM with more than one bridge during the KVM installation? a. It was a long shot but I have tried bridge=br0,br1 ;

Greetings, I'm attempting to get several virtual machines setup on a Fedora19 host system, with the traditional bridge network devices (br0, br1, etc). I've done this many times before with older versions of Fedora (16, 14, etc), and it just works. However, for reasons that I cannot figure out, the bridge doesn't seem to be working in Fedora19. While I can successfully connect to

Maybe my google-fu is failing me, but I have spent the past couple hours looking at how to add a vnet? Device to my KVM host running CentOS 6, and for the life of me I can't get this going. >From all my research if I want to add a device I should just do 'brctl addif br1 vnet14' if I want to add a vnet14 to bridge br1. When I do this, I get: # brctl addif br0 vnet14

You most definitely do not need to destroy and re-create a VM just to add a 2nd network interface. I don't think those vnet interfaces got created by the host OS. I believe those are created by KVM (or libvirt) when you start a VM. I could be wrong though. But I just checked on my CentOS 6 KVM host machine and I see as many vnet interfaces as many VMs are currently running (or if one VM

<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

BTW, adding a 2nd virtual nic to a guest can also be done with command line tools (I just googled this for you) : https://kashyapc.fedorapeople.org/virt/add-network-card-in-guest.txt ( It came up as 1st result when I searched for: virsh add network interface to existing guest ) But if you look at the bottom of this guide, they also mention that if something goes wrong, they resort to using

Hi, I want to connect two pc`s on a redundant way with each other. On those pc`s a 64 bit ubuntu 11.10 is running with kernel version 3.0.0-16-generic. Setup1: ---------- PC1: PC2: br0 br1 | | -- eth0.1000 ---------------------------------------------------eth0.1000 | | __eth1.1001

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

I am experimenting with routing tables to obtain a little understanding of how things work. I have a kvm hypervisor host (KVM1) with two physical Ethernet nics configured as bridges (br0 and br1). KVM1 br0 is configured with a public ipv4 address [x.y.z.42/24] and br1 is configured with a private ipv4 address [192.168.216.42/24]. A second kvm hypervisor, KVM2, is similarly configured albeit with

Hi, Sorry of this is the wrong list, trying to find some help. I am trying to set up 2 KVM hosts using Debian 9 (connecting to a 3 node Centos 7.4 gluster cluster) To get the bandwidth I have bonded 2 NICS each end. However while the network works fine for the Debian VM host the VM guests cannot connect/get an IP using DHCP connecting to br0. (Same setup on the Centos end works fine however)

Stephen Hemminger, Yes,I use V2.4.17. Which patch can I use? Or can you tell me the reason,so that i can modify my Kernel.I use this kernel at the embeded system. >Haisen.Zhang wrote: > >>shemminger? >> >> I have a problem with brctl application,following is my operations: >> >> vconfig add eth0 3 >> >> brctl addbr br0 >> >>

I built a CentOS 6 machine to host several CentOS 6 guest servers. As all guests will be Internet facing I set up the host with two bridged NICs and assigned an Internet facing IP address to br0 and a local IP address to br1. Each guest was installed using br0 and br1 with virtio drivers. On each I assigned an Internet facing IP address to eth0 and a local IP address on eth1. So far so good. I
