Oh, here's a guess: maybe you think that to do that you'd have to
restart all containers?  No, you would not.  It is as simple as:

mount /vz -oremount,noatime

on the running system.  Alternatively, you may add the noatime option to
/etc/fstab first and then issue simply:

mount /vz -oremount

This also serves to validate your /etc/fstab edit, so you will get no
surprises on the next server bootup.
