You can point virt-builder to another repo; and in fact, the guys on
the libguestfs development list said that them hosting their own
template repo was meant to be a temporary measure, and that long-term
they'd like to see distros hosting their own templates.

But as to "why", did you miss that "yum install libguestfs" wants to
bring in an *additional* 178 packages, more than doubling the size of
a base installation? :-)

I think for a lot of people that will be fine; but I agree with KB,
that we should also have a really lightweight way for people to just
get VMs up and running.
