There should not be any v_xxx script in a vserver anyway. They get there because
people most of the time create a vserver by cloning the root server, so they got copied
there. The v_xxxx script have no purpose at all on a vserver. A vserver is tied
to one or more IP and has to use only those. A root server has access to all, so the
v_xxx script were created to limit the scope of a given service easily. See below

The /etc/vservers/*.conf are used only for the root server. Normally, for new
projects, the root server does not run any service, or at most sshd. As such
it does not conflict with any vservers. But most people start from a live server
already having some service and then add few vservers. So they have to
limit the scope of the services in the root server. By default, the v_xxx script
limit to one IP: the main IP of the eth0 device. This may be a problem for
some server. Maybe you want eth1 or more than on IP. So you can create
a file /etc/vservices/xxx.conf and enter
IP=whatever_IP
Note that version 0.18 do not support multiple IP there. I just fixed it. While doing
so I reworked all the v_xxx scripts to use a common helper script, so they are
less redundant.
