OpenVZ is what you are looking for. Short summary:
- only one kernel shared between host and guests (lower overhead)
- memory and VFS cache can be shared (huge memory win)
- easy to setup and manage
There are some drawbacks as well because of the characteristics. But
depending on what you want to do, OpenVZ can be useful.
