Setup VPS under OpenVZ VPS. Is it possible ?
I have a question.

Why?
I've heard that it can install OpenVZ inside a XEN.

Yes, I've done it before. It was a honeypot for HyperVM/Kloxo exploit testing right after the vaserv incident. It was an OpenVZ CT0 under a Xen HVM VPS.
However, to your very first question, the answer is no. It's not possible to setup a VPS within an OpenVZ VPS. VZ is technically a glorified jail/container.

Being that you can run your own kernel in a Xen VPS I wouldn't see why it wouldn't be possible but I've never tried... In an OpenVZ VPS it would definitely not be possible as you would basically be sharing the system kernel.

Thanks for the replies.
What are other virtualizations which can be used to run vps under it?

A vm inside a vm is a really bad idea. It will be very slow, and it will use up a lot more cpu.

Hi,
To answer your initial question:
yes it is possible
now the other question is is it usable and the answer to that one is no, not really.
It can be done but rather as a scientific project/proof of concept than any real life situation.European Xen based VPS Hosting

I do not agree with Wamoc and webangel_ie.
What we are all talking about here is called "Nested virtualization". In fact, there was a talk at the last Xen Summit in Shanghai about it. There's a Chinese programmer, I guess that is working for Intel, that did some very nice work for nested virtualization. What happens with Xen, is that the hypervisor is aware of the fact that a virtual machine is running in a virtual machine. You continue to have the illusion of nested virtualization, while the hypervisor in fact talk directly to the VM inside the VM.
The result with what did Qing He is that performances are not as bad as you may think. I would advise you to run the very latest Xen kernel though (4.0.0 or even the latest hg, as there has been some recent (few days ago) patches sent by Qing He on the xen-devel list).
Slides: http://www.xen.org/files/xensummit_i...ested-virt.pdf
Video: http://www.xen.org/media/Movies/XenS...ualization.MTS (1.1 GB HD format)
In the slides, Qing He explains very well that there is no reason that nested virtualization would run so slow. Technically, he got some very good points.
Note that the only thing that is possible is to run a domU inside a dom0 inside a dom0 (in other words, it's not possible to do HVM inside HVM, if I understood correctly). I did try all this, and it does work.

Do we have to set unique ip to each vps? Can't we share the ip?

you can do port forwarding form one ip as always so different vps have different ports assigned but it wouldn't be possible to have two web servers listening on port 80 within the single ip (probably https is better example because http can be achieved with layer7 firewall and or http proxy)

layer7 for linux http://l7-filter.sourceforge.net/protocols
mod_proxy for apache http://httpd.apache.org/docs/1.3/mod/mod_proxy.html
both of them allow you to control to some degree where http protocol connects based on the hostname rather than ip address so you can have different sites on different boxes.European Xen based VPS Hosting
