It's maybe /etc/named.conf not overwrite by /home/bind/etc/conf/named.conf.
Better try switch to djbdns and switch back to djbdns.
Mustafa this process not only keeps the VM but the dedicated server with virtualization and you can not kill him. Zobi? need to reboot the dedicated server has shutdown.
The problem I have with making a backup VM:
vzdump 100 --remove 0 --mode suspend --compress gzip --storage local --node xxxx
Inside the VM with Kloxo-MR.
