[Libguestfs] Question how to implement remote access

Hello. I've been finding a good solution to monitor virtual machines' status such as memory, disk, cpu, etc, and I found this as a tool for measuring disk/image status. I have a question while using the libguestfs-java library; I'd wanted to implement a sample app which retrieve the disk information remotely. Is there any way, i.e., specific API(s) to connect with a host where kvm/qemu has been installed from a remote node, to access and get VMs' disk related information remotely? I read JavaDoc and libguestfs-java sample code from http://libguestfs.org/guestfs-java.3.html, but I could not find such an example. Thanks in advance! best regards bgkim
