Are you facing the following error when you try to boot up a Virtuozzo VPS ?
mv: cannot move `/etc/resolv.conf.xxxx' to /etc/resolv.conf': Operation not permitted ERROR: Can't change file /etc/resolv.conf File resolv.conf was modified
This might be if you have set an immutable flag on the file
This file is automatically generated at boot based on the VPS conf.
So, remove/rename the file /etc/resolv.conf ( for the respective VPS )
from the Virtuozzo node and reboot the VPS in question.
