CentOS virt - Nov 2015 - Errors with virt-manager

Hi all,

  When I try to connect to a remote KVM host from my CentOS workstation 
(both are CentOS 7.1 fully patched) using virt-manager (ssh+qemu), the 
following error is displayed:

Error launching connect dialogue: 
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name 
org.freedesktop.Avahi was not provided by any .service files

Traceback (most recent call last):
   File "/usr/share/virt-manager/virtManager/engine.py", line 714, in

     self._get_connect_dialog().show(src.topwin, reset_state)

  Searching about this error, I have found this patch:

https://www.redhat.com/archives/virt-tools-list/2014-December/msg00165.html

  But applying this solution doesn't resolves the problem.

  Any idea why?
