Unless your disks are on shared storage, and are accessible using the same paths at the monitoring machine, in which case it might work. [To see if this could work, try doing the following command from the monitoring machine: virsh -c qemu+ssh://root@hypervisor.example.com/system dumpxml name_of_a_guest and if the command works and the paths in the returned libvirt XML are also valid on the local monitoring machine, then libguestfs may work remotely.] I suggest that you use a Java remoting library such as RMI, SpringSource remoting, JBoss remoting or others. It does mean that you'll need to run a small service (the Java RMI server) on each node. You can see a similar idea -- but implemented in Python -- here: https://rwmj.wordpress.com/2013/05/07/using-libguestfs-remotely-with-pyth...
