I had the same problem with Gutsy domU on Gutsy dom0. It is caused by xend generating a new MAC address each boot, udev recognises this as a new card and therefore creates a new entry.
Add MAC address to the domU config file like: vif = [ 'mac=00:11:22:33:44:55' ] See http://www.cl.cam.ac.uk/research/srg/netos/xen/readmes/user/user.html#SECTION02220000000000000000 for more info on what MAC address you should use. -- domU fails to get network connection https://bugs.launchpad.net/bugs/150805 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
