Please do not forget that libvirt may start guests by itself, even if libvirtd is started by pacemaker. This is true for at least latest libvirt releases - it starts all guests marked for autostart AND all guests being started when libvirtd was last active (f.e. just before node was fenced). The only solution I found to prevent this is to delete all /etc/libvirt/qemu and /var/.../libvirt files early during boot sequence.
