-1 because the question is very vague. Nothing about what you need this for is described. I'd say you're lucky that someone even tried to answer you. – Frands Hansen Jan 2 '12 at 9:56

KVM, Xen and VirtualBox provide you full virtualization.

LXC (Linux Containers) would be a more light solution, being similar to FreeBSD jails or Solaris zones.

All mentioned are free and open source, but since your question was very short and lacks details, I won't type a longer answer for now.

There are many options available on vmware website. Some of them are free. Others are not.
