There is a tool in which you drag-drop a machine and it appears as a
circle (sorry not a rectangle).
You can configure to have more or less interfaces and have uml or kvm
The circle represents a machine and has a name and its interfaces are
smaller circles in the big circle representing the machine.
You can then drag-drop small circle representing lan(s) and with clicks
you can connect the machine interfaces then ping between interfaces.

dia does not manage virtual machines, cloonix does!

dia - not sure about saving as XML, but it can save in a whole lot of
other formats.
