I my case, a Realtek NIC that was present as 'eth0' became 'ens3' after reboot, thus the network settings from /etc/sysconfig/network did not apply. It turned out that the unique hardware IDs under /var/lib/hardware/udi were duplicated. In Yast network settings, the old adapter entry was still shown, but the NIC appeared as new unconfigured item. Maybe this was due to the fact that another driver module is used with the new kernel, I do not know. The Realtek NIC is very common, and in this specific case was the default adapter in a KVM/QEMU virtual machine, so this will happen very often. If the naming of the UIDs (or the device names) cannot be retained, at least the instructions for an online distribution upgrade should include a warning, because the whole purpose of an online distribution upgrade is defeated by this bug! Reproducible: Always Steps to Reproduce: 1. Do online distribution upgrade as specified here: http://en.opensuse.org/SDB:System_upgrade, e.g. from openSUSE 12.3 2. Reboot system Actual Results: Network connectivity not restored. Expected Results: Network functioning as before the upgrade. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
