Hi
you should do a little change in your /etc/ssh/sshd_config of the
host-machine:
-----------------
ListenAddress <ip_of_host>
-----------------
... and restart sshd-process.
The result is, that the host only listens on that IP, and connections to
the other IPs can go to the vservers.
You have to do this with most services on your host.
