Domain is not resolving

[DZII]

Fresh Install of ubuntu and Vesta and Followed all steps to setup dns and domain still does not point
http://vestacp.com/docs/#how-to-setup-v ... ameservers

I was able to get domain working by doing

sudo apt-get install apparmor-utils
sudo aa-complain usr.sbin.named
sudo /etc/init.d/apparmor stop
sudo /etc/init.d/apparmor start
service bind9 restart

Still In Question ?
If your host file is set before install as example
127.0.0.1 lcoalhost.localdoamin lcoalhost
ip address hostname.domain.com hostname
why does the installer add 127.0.0.1 hostname.example.com 2 times in /etc/host file ?
