Thanks for taking the time to make this bug report to make Ubuntu better! I tried reproducing your failure and unfortunately am not able to in a VM/container setup. I think this may need some extra configuration to reproduce the failure.
Starting with something basic, would you mind sharing these 2 files? Please remove/censor any information you do not want to share such as MAC address. /etc/libvirt/qemu/networks/default.xml /etc/dnsmasq.d-available/libvirt-daemon And any other configuration files that you think may be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055455 Title: dnsmasq-base causes network device virbr0 to shut down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/2055455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
