[Solved] virNetServerMDNSStart:460 : internal error Failed to create mDNS client: Daemon not running

Fix:

Further investigation found avahi was needed for this to work. The final fix was running

yum -y install avahi
/etc/init.d/messagebus restart
/etc/init.d/avahi-daemon restart
/etc/init.d/libvirtd restart
/sbin/chkconfig messagebus on
/sbin/chkconfig avahi-daemon on

[Solved] x.x.x.x Sorry, the domain is already pointed to an IP address .....

Problem: Using nameservers with the following IPs: x.x.x.x Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver.

Solution:  Tweaksetting -> Allow Remote Domains -> On .

Done
