Is there an OS-level Virtualization distro?


Hello,

I'm a newbie to Virtualization and have been doing a bit of reading on it.

Is OS-level virtualization some type of Linux distro like Ubuntu,CentOS,etc., or is it an app that sits on an OS?

I read on Wikipedia,
Quote:
OpenVZ (Open Virtuozzo) is an operating system-level virtualization technology based on the Linux kernel and operating system.
that's what got me a bit confused.

There are a lot of confusing terms. In a basic sense there is at one end of the spectrum an unsupported hardware running some os with a complete software implementation of a computer. This was the original emulators and we still have parts left like bochs and maybe some versions of qemu and some old commercial emulators.

Today we have any number of hardware designed to take advantage of vm's as well as both bare metal and some minimal OS's to take advantage of both the clients and hardware.

I suspect the next step is to figure out a true virtual computer that can run any OS in hardware and multiple at the same time. Which comes back to your question. Do you need some fraction or part of an OS to control the vm's now? Yes you do.
