But how is this possible if the osa-dispatcher can not connect to it's 
own loopback/ip-adress for the jabber connection?
No firewall or network related stuff there..

I will do that as a backup option.
If I get it correct: rhnsd is only polling the Spacewalk jobs, it won't 
automatically install new upgradable packages if I don't set them to 
upgrade right?
(It only pulls the jobs Spacewalk has started)
