Connections Driver VirtualBox

Good Morning! My name is Cláudia, I'm trying to use the Connections to VirtualBox driver from libvirt.org on Pacemaker to start a virtual machine created with the VirtualBox hypervisor, so far I haven't been successful. Could you send me a practical example of how to use the driver with the VirtualDomain feature in Pacemaker? The examples I found only demonstrate the use with Xen and Qemu. Thanks,
