I have a 1 server with 8GB RAM and 2xQuadcore Processors. It currently has the Xen XCP installed on it, and centos6.2 x64 running on a virtual machine.

I have a server control panel software that I want to use and it allows the administration via a web interface for Openvz machines.

My questions are:

  1. Would this be considered bad practice?
  2. Would there be a big performance hit?
  3. Should I avoid this all together or am I going about it all wrong?

Thank you in advance.


OpenVZ is "chroot() on steroids" — virtualization through better processes isolation, so it should be absolutely okay to run OVZ inside XEN.

  • Really appreciate your reply back. The control panel I was considering using was ISPconfig3 but on their forums they told me that you should never run a virtual machine inside of a virtual machine. I am new to virtualization and just wanted to make sure whether or not I was going about it the right way. – Damainman Jun 4 '12 at 20:55
  • How many times should you be told that OVZ is different kind of virtualization? ) en.wikipedia.org/wiki/Operating_system-level_virtualization – poige Jun 5 '12 at 1:59
  • 1 time I believe?? Thank you for the link, definitely cleared up a lot :). – Damainman Jun 5 '12 at 6:34
  • Also make sure you give lxc a try. – kolrie Aug 21 '12 at 1:45
