You write the XML yourself to describe the initiall characteristics of the
host scenario you are trying to simulate. eg the XML file describes what
guests you want to pre-create, the capabilities of the host, the storage
pools, storage volumes, etc, etc. The examples/xml/test directory shows
some illustrations of how todo this.

Why can't you modify your client. It is pretty reasonable to have the
URI be configurable for any libvirt based app, so I don't see why this
should be a blocker.

I don't see any compelling reason to create a new driver for the scenario
you are describing, and would likely reject any patches aiming to do so
based in the info you have provided so far.
