Hey, I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows: ____ ____ / VM1\______br0_______/ em1\ \____/ | \____/ | _|_ /VM2\ \____/ virbr0 is the virtual network switch VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively. em1 is the default

Hello, I am experiencing what may be a unique problem with operating the bridge. My hardware is custom Freescale MPC875 processor based with one ethernet (eth0) and one hdlc (hdlc0) WAN port and I am connecting two of these boards together using the WAN ports over a long distance - essentially two bridges in series. They are running Linux 2.6.15 with bridging enabled in the kernel

Santiago, I appreciate your offer. I'm not really a kernel hacker, however I do know C and I would be willing to try if you point me in the right direction. Here is my first attempt using Debian running on an UltraSPARC: debian{root}:/root<512>strace -f -F -v brctl addbr br0 execve("/usr/sbin/brctl", ["brctl", "addbr", "br0"], [/* 16 vars */]) =

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

With recent 2.6 kernels, the command brctl delbr br0 hangs during shutdown, and the kernel prints this message again and again: unregister_netdevice: waiting for br0 to become free. Usage count = 1 I was able to reproduce this problem with several kernels between (and including) 2.6.9-rc1 and 2.6.11-rc2-bk9. I haven't tried later versions than 2.6.11-rc2-bk9 yet. 2.6.8.1-bk2 still works

Hi I have been using Shorewall for a while now and find it very useful and easy to configure, I am learning iptables and having trouble getting the bridge to successfully work with squid, although I get it working with Shorewall straight away?

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 wondering if anyone can help. I have two NICs on a debian sarge based system and current running as a bridge (br0) which consists of eth0 and eth1.
