Hello to all xen gurus (and gurus to be :-) ), first the usual disclaimer: I am new to xen (besides 2 weeks of intense looking into it); I tried to find in depth documention to networking with xen, but I fould only hints on how much more info I would need. So please bear with me if my questions are too simple and kindly point me to the right docs. One of my test systems has 2 NICs (different chipsets). I managed to compile and run a xen0 kernel based on the debian inofficial packages. When I tested networking I found the following: I had activated the drivers for both NICs in the kernel. When I activated both NICs in /etc/network/interfaces, no networking at all was possible. When I activated one of the NICs in /etc/network/interfaces, then either the outside could be reached (everything outside my gateway), or the local subnet the xen0 server is placed into. I did not succeed in getting both to work. I had to deactivate one of the NIC''s device drivers in the kernel. Thank God is was a system with two different types of NICs. So what do I do with a system that has two IDENTICAL NICs? And where do I find in depth documentation of networking with Xen? I have read about the bridge in standard config, but found no hint on what else could be done. I would escpecially look for docs about - the VLAN feature, - filtering network traffic between the domUs, - how to use multiple NICs. Any help or hint is appreciated! Thanks in advance, Dirk _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Maybe you could post the output of ifconfig -a, route, etc so we actually have a chance to trace your problem?> And where do I find in depth documentation of networking with Xen?

So the best place to start looking for in-depth documentation would be the kernel documentation. Look into /usr/src/linux/Documentation/networking/bridge.txt for bridging, /usr/src/linux/Documentation/networking/alias.txt for ip-aliases Starting point for vlan: http://www.candelatech.com/~greear/vlan.html for filering network traffic on a bridge, have a look at: http://ebtables.sourceforge.net/ /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
