The specfile requires avahi during install if libvirt was built with
avahi support, but there are many situations where it is undesirable
to install avahi due to security concerns. This patch requires only
the avahi-libs package, which is needed by libvirt to call the
function that tries to attach to the avahi daemon, but will instead
silently fail because the avahi-daemon is in the main avahi package,
and that package isn't installed.

v1 removed the requires completely, but that caused libvirtd to fail
to load due to missing libraries.

Okay, I pushed it. Thanks for the quick review.
This is definitely a nicer solution - we compile against the
library, so we only need the library present, without also firing up the
main daemon. The library itself is safe whether or not 'avahi' is also
installed. And based on IRC chats we had in the meantime, I feel more
comfortable that you actually got something tested with 'avahi' uninstalled.
Yes, forgot to mention that. I tested by doing this:
rpm -qa | grep avahi >/tmp/packages
cat packages | xargs rpm --erase --nodeps
yum install avahi-libs # (this only installed the one package)
then I tried installing an unmodified libvirt rpm, which gave an error
due to the avahi package being absent. After that I installed the
modified libvirt rpm, and successfully restarted libvirt.
(After that, I reinstalled all the packages in /tmp/packages, because
there's a boatload of stuff that depends (directly or indirectly) on
avahi :-O )
