See below. Reproducible: Always Steps to Reproduce: emerge iproute2 with USE="minimal" Actual Results: When creating a domU I always got Error: Device 0 (vif) could not be connected. Could not find bridge device xenbr0 Expected Results: Created and connected the virtual interface to the bridge (which was present in ifconfig -a all the time). jakub@gentoo.org 2007-09-29 22:25:16 0000 So don't do it, what exactly are you expecting here? marineam@gentoo.org 2007-09-29 22:52:59 0000 I guess I could die on install if iproute2 was built with minimal, but I would bet lots of random crap breaks in general when a system is built with the minimal use flag. lama@lamamail.de 2007-09-30 00:41:45 0000 > So don't do it, what exactly are you expecting here? I had no clue what was wrong and came across the source of the problem by accident. There should be a pointer somewhere that xen needs ip (or whatever) to work correctly. marineam@gentoo.org 2007-09-30 01:03:03 0000 (In reply to comment #3) > > So don't do it, what exactly are you expecting here? > > I had no clue what was wrong and came across the source of the problem by > accident.

In general I would recommend not using the minimal use flag unless you know exactly what functionality it is stripping for a package and you are worried about space (ie tiny embedded systems). lama@lamamail.de 2007-09-30 01:20:40 0000 Okay, thank you :) rbu@gentoo.org 2007-09-30 01:44:29 0000 Alexander, this is not a 'major' bug. Stop making it one. lama@lamamail.de 2007-09-30 11:06:27 0000 I think "major loss of function" is a pretty good description of not being able to use networking with Xen and not knowing why. I bet I'm not the only one who built a dom0 with USE="minimal". marineam@gentoo.org 2007-10-02 00:46:09 0000 Updated xen-tools-3.1.0-r1 to issue a warning if iproute2 was built with USE=minimal. Closing.
