Code review comment for ~paride/utah/+git/utah:server-vm-xml

Thanks for reviewing this one Michael. Well you said it: currently there is no easy way in utah to alter the test environment, utah hasn't been thought to do so. We're already deviating a bit from what I believe are its original design decision, moving from very generic libvirt XML files to arch-specific ones from which we inherit part of the machine configuration, without rewriting it. I see how testing different boot environments is important; we'll have to find a way.
