  Operating system-level virtualization enables multiple isolated ex- ecution environments within a 
  single operating system kernel. It has the best possible (i. e. close to native) performance and 
  density, and features dynamic resource management. On the other hand, this technology does not allow 
  to run different kernels from different OSs at the same time. Examples: FreeBSD Jail, Solaris
  Zones/Containers, Linux-VServer, OpenVZ and Virtuozzo.
