What about setting up a temporary NFS export on the host and mounting
that on the guest? I've done installs using yum/rpm directly from the
NFS mount, eliminating the need to ever copy the RPMs into anything
more than working memory. If network security is an issue, I'm sure
you could use a combination of iptables rules and NFS export options
to limit access to that single box as well (though, I haven't done
that one).

Here's to hoping I didn't miss something blatantly obvious...
