Hallo, I have running xen-4.2/linux-3.8 (compiled) on any hosts. - dell pe r720: drac, eth0-3:igb squeeze -> boot_xen:ok net:ok bridge:ok - dell pe R620: drac=eth0, eth1-3:tg3 wheezy -> boot_xen:ok net:ok bridge:fail So i running "xend start" (or "xenbridges start") on my patient (R620 with broadcom tg3) network will be lost: RTNETLINK answers: File exists Failed to bring up eth1. It seen to be a problem near scripts/network-bridge:do_ifup() workaround seen to be: simple add "ifconfig $1 up" Whats going wrong? Which direction should I look now? (my(config), tg3, wheezy, ...) details below.
