+Subject: Allow libvirt to kill unconfined domaiens
+
+On startup libvirtd runs a number of QEMU processes unconfined such as:
+
+  /usr/bin/qemu-system-x86_64 -S -no-user-config -nodefaults -nographic -machine none,accel=kvm:tcg -qmp unix:/var/lib/libvirt/qemu/capabilities.monitor.sock,server,nowait -pidfile /var/lib/libvirt/qemu/capabilities.pidfile -daemonize
+
+libvirtd needs to be allowed to kill these processes, otherwise they
+remain running.
