As mentioned in the commit message, I wanted the resulting XML files
to be representative of something you might actually encounter in the
wild: simple, but not trivial. Using '--disk none --network none'
would mean we would no longer see what virt-install defaults to for
storage controller and network interface, which is a big part of why
these tests are useful in the first place.

You have a point about '--random /dev/urandom', though: if it's
dropped, then all guests still get an RNG *except* for s390x guests,
which tells me there's some architecture-specific code that needs to
be amended there. I'm okay with both you dropping that option before
pushing or leaving it there: either way, I'll post follow-up patches.
