Rewording in Short comparison
== Short comparison ==
The three techniques differ in complexity of implementation, breadth of OS support, performance in comparison with standalone server, and level of access to common resources. For example, VMs have wide wider scope of usage, but poor performance. Para-VMs have better performance, but can support fewer OSs because of need to port modify the original OSesOSs.
Virtualization on the OS Level level provides the best performance and scalability compared to other approaches. Performance difference of such systems can differ only about 1-3be as low as 1…3% from , comparing with that of a standalone server. They [[Virtual environment]]s are usually also much simpler to administer as all of the Virtual servers them can be accessed and administered from the hostsystem. Generally, such systems are the best choice for server consolidation of same OS workloads.
