Hello Guys,
I have the following situation, where users on the host become owners of the
home directories of the users of the guest.

root@nevir:/var/lib/vservers/vn/home# ls -alh
total 44K
drwxr-xr-x 11 root root 4.0K Mar 25 18:42 .
drwxr-xr-x 20 root root 4.0K Mar 17 00:39 ..
drwxr-xr-x 3 services services 4.0K Mar 24 00:16 agra
drwxr-xr-x 6 spectre spectre 4.0K Mar 25 13:30 cipri

As you can see user services on the HOST can now have full access to the
home directory of user agra on the guest.

Is there a way this can be solved, or do I have to start numbering the UIDs
and GIDs on the Guest from higher numbers?

p.s. Some useful information would be:
