Thomas, thank you for taking the time to file this bug report and help us make Ubuntu better!
The upstart job is, indeed, ignoring any settings that used to be set in /etc/default/libvirt-bin. Seeing as there is no warning about this in the release notes or changelog, I think this is a regression, as it breaks on upgrade from lucid to maverick. As a workaround, you can take all the settings from that file and manually add them to /etc/init/libvirt-bin.conf as env KRB5_KTNAME=/etc/libvirt/krb5.keytab There is no need for a special script to do that. The fix should be to source /etc/default/libvirt-bin and respect the flags as they were before, at least until the release following the next LTS. Marking Triaged ( as Ubuntu is upstream for the upstart job ) and setting Importance to Medium, as this is a regression on upgrade, but only affects users with non-default configurations. ** Tags added: regression-release ** Changed in: libvirt (Ubuntu) Status: New => Triaged ** Changed in: libvirt (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. https://bugs.launchpad.net/bugs/708172 Title: service libvirt-bin start does not set KRB5_KTNAME as required -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
