The other use case that this is working towards is that of matching an existing VM image to a (set of) hosts it can possibly run on. Think of this in the context of a big data center mgmt tool: you have a large number of hosts, with some variation on the exact virt platform they are running. You'd like your tool to be able to place a VM (image) intelligently on an appropriate host - and the first question you need to answer is 'Can this guest run on this host'; the virt-image code is of course only a small fraction of what you'll wind up needing, but it's a first small step in that direction.
