How to remove/delete visibe mountpoint all containers?
You have link from /etc/mtab to /proc/mounts. You can try removing this link, copy contents of /proc/mounts to /etc/mtab and remove all occurrences of /vz/root from the mtab. After that mount would keep correct contents of mtab without /vz/root
