One advantage of full virtualization is that the operating system does not need to be modified in order to run in a virtualized environment. In this scenario, the guest operating system is provided a complete virtual physical environment in which to run and, as such, is unaware that it is running inside a virtual machine. Full virtualization provides complete abstraction between the hardware and the guest operating system. There are two common approaches to virtualization - full virtualization and para-virtualization. In this and subsequent chapters we will look at KVM based virtualization hosted on an Ubuntu system.įull Virtualization vs. Options include VMware, VirtualBox and KVM. There are a number of ways to implement virtualization on Ubuntu. Similarly, virtualization allows you to run Windows operating systems from within an Ubuntu system, providing concurrent access to both operating systems. You simply start up a virtualized version of the new operating as a guest operating system.

For example, you can try out a different operating system without having to re-partition the disk, shut down Ubuntu and then boot from the new system.

Virtualization is also useful in terms of trying out different operating systems without having to configure dual boot environments. Virtualization has come to prominence in recent years because it provides a way to fully utilize CPU and resource capacity of a server system whilst providing stability (in that if one virtualized guest system crashes, the host and any other guest systems continue to run). Virtualization is the ability to run multiple operating systems simultaneously on a single computer system.
