My local Dom(0) network stops working as soon as network-bridge is started. I''m running centos 5.3 and installed xen from repository via yum. I have a LinkSys 10/100/1000 PCI card in my machine. Driving me crazy! Any ideas? I''ve stumbled upon a couple possibles regarding using ethtool which seems to then render my bridge unusable. Any help appreciated for someone who''s trying real hard to become a Xen user. :) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

On some cases (like a Broadcom tg3 that I have) the problem is that the NIC hardware or firmware doesn''t support bridging properly. I had to upgrade its firmware to get it working correctly. I suggest you check for NIC firmware upgrade, or try another NIC. Even onboard NIC usually works well. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The network-bridge script didn''t seem to complete properly (eth0 renamed to peth0, but xenbr0 did not exist and no IP addresses assigned to any interface), which resulted in no network connectivity at all. To fix it, I had to create the file /etc/sysconfig/network-scripts/ifcfg-xenbr0, which is basically an exact copy of ifcfg-eth0 except you have to modify the lines DEVICE=xenbr0 and ONBOOT=no (otherwise CentOS will try to bring up xenbr0 at boot time before xend). The network-bridge script seems to rely on the existence of this file. Thanks Matthias SOUTH PACIFIC SEEDS PO Box 934, GRIFFITH N.S.W. 2680.
