Description Perry Myers 2012-02-17 19:40:14 UTC 
avahi is included by libvirt, but this can be disabled manually and the dependency removed.

So, need to remove avahi from the images via package blacklisting and configure libvirt to not look for avahi

* add mdns_adv = 0 to libvirtd.conf
* rpm --erase --force avahi* in the blacklisting section of the
  kickstart
Comment 1 Fabian Deutsch 2012-03-28 09:06:32 UTC 
libvirtd is linked against files in avahi-libs, so I don't see that we can just remove those libs, even if we disable mdns support in the conf.

$ ldd /usr/sbin/libvirtd | grep avahi
	libavahi-common.so.3 => /usr/lib64/libavahi-common.so.3 (0x0000003a06a00000)
	libavahi-client.so.3 => /usr/lib64/libavahi-client.so.3 (0x0000003a08e00000)

Did you have other thoughts?

At least we can disable avahi in the conf.
Comment 2 Mike Burns 2012-03-28 12:07:14 UTC 
Dave, 

You confirmed that avahi isn't used by libvirt at all anymore right?  Is there a reason it's still linked?  Can we drop the package completely from ovirt-node or should we keep the package and only disable the service.
Comment 3 Dave Allan 2012-03-28 13:51:53 UTC 
It's still linked against avahi because the user can turn on avahi if they wish, so avahi-libs can't be removed.  The daemon can be, however.
Comment 4 Fabian Deutsch 2012-03-28 15:15:06 UTC 
The avahi daemon is already removed from node thus I'm closing this.
Comment 5 Fabian Deutsch 2012-03-28 16:06:06 UTC 
Sorry for the noise.
There is still this small patch wich disables avahi in libvirt:
