You can cat /etc/xensource/network.conf to check it out. If it's running in openvswitch mode, don't use brctl to manually play with the bridges, that could be the reason it's panicing.Using brctl in openvswitch mode isn't usually the right thing to do, but it shouldn't cause a panic. If it does, then that's a bug that we, meaning the Open vSwitch developers, need to fix. (But this is the first I've heard of such a problem.) Hi Ben,That was just a supposition, I don't remember which version of openvswitch is running on XCP 1.1 beta, and my sandbox is down so I can't try to reproduce it at the moment.I'm not an expert, but regardning the panic messages, for me it looks like it's trying to load the bridging module (modprobe, br_device_event, etc).

Something like openvswitch having the hook for bridge functions and the kernel panicing when it try to loads the linux bridge module.Again it was only a supposition, I can be totally wrong. So pardon me if I'm completly out of the subject. I just don't see what else could be confusing the kernel at this point. Cheers, SÃbastien ps: It looks like to me that your reply didn't make it to the list _______________________________________________ xen-api mailing list xen-api@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/mailman/listinfo/xen-api
