ok thanks for the info , I have a few more questions:
1)I am running RHEL 4.x on the server . What will be the OS for mine VPS i
create on this server.
2)I already have some files to and some important databases on this VPS what
will happen to those files once i create VPS or install openVZ.
3)What will happen to the IPs , specificaly to the main IP. I mean once i
install openVZ will mine RHEL 4.x stop to work and i will need to create the
VPSes for it to work and mine mian IP will be there to configure VPS only.
Also apart from the instal;lation guide available on site
http://openvz.org/documentation/guides/installation/quick-in stall , does
anyone have some notes for easy installation. pl provide them that will be
handy.
Pl. provide the info.
Thanks,
Abhishek jain

You can have different distros in different VPSs, including RHEL 4.

I am not sure what do you mean by "on this VPS". If you mean "on this
server", the answer is they will stay as is.
Still, from the security standpoint, after you have installed OpenVZ,
you should move all the services/daemons (other that sshd and some
needed stuff like syslogd and crond) running on the machine into a VPS
or a few. Otherwise you could have problems.

The Linux you have on your server will pretty much stay as-is. If you
want to create VPSs you need more IP addresses for them.

I am not sure how it could be done even more simple than described...
Perhaps an installer script; but the installation is what you do just
once and it's probably better to do it manually in this case, just to
get sense what is happening when you install OpenVZ.
I suggest if you find it too cumbersome you should hire some system
administrator to do that for you, or ask for fee-based installation and
support from OpenVZ; ask for it to sales@openvz.org
PS Looks like you haven't read the documentation at all, going the easy
way of asking before reading -- please do read the docs first. This is
open source project not a commercial entity so free support and the
answers are provided on a 'best-effort' basis and we can not answer each
and every question which is already answered in docs.
Well, of course we (well, not we, but OpenVZ support team) can, if you
buy OpenVZ support. Please do not see it as I am trying to sell
something -- I do not; I just try to let you know how are things are
done here, what are the possible ways and options.
