Public bug reported: After upgrading to Kubuntu 18.10, my virtual machine (KVM/Qemu/Libvirt) is no longer able to connect to the Internet.
This problem has already been reported on Fedora. See: https://bugzilla.redhat.com/show_bug.cgi?id=1623868 I've modified /etc/firewalld/firewalld.conf to select the iptables backend instead as suggested in that bug report. After this change, my virtual machine can now connect to the Internet again. Proposed solution: Ensure that firewalld uses the iptables backend by default until the root cause is fixed in firewalld.
