Using a virtual private server is a common practice for all of those wishing to split a server.
Each server may run a full operating system and may be booted and rebooted just like any normal system.
The alternative system is referred to as the "guest" operating system or a "virtual machine.
" The hypervisor also known as the virtual machine monitor is what allows more than one virtual machine at once.
The guest system is ran on a virtual platform where all of the execution is monitored and executed.
It isolates failures to one operating system and prevents the sharing of hardware.
The hypervisor creates, destroys, and manages every part of the guest system.
The guest operating system may be paravirtualized so that it presents it with software interface.
It reduces the time that it takes to perform operations that are usually difficult to run in a true machine based environment.
Paravirtualization allows for the guest "virtual machine" to be simpler by relocating critical tasks to the host domain and allows for a higher quality of performance and satisfaction with the operating system.
A virtual set of hardware is created for the guest system that is exactly like the real thing.
In order to do this, the hypervisor translates, maps, and converts all requests from the guest "virtual machine" into whatever the request may be for the host.
With this method, most any system can be virtualised and run a guest system.
The original operating system needs no modification, but it's good to have a cpu that supports virtualisation for the full and best performance.
There are many uses of server virtualization.
One big use is uniting shared web hosting services and dedicated hosting services.
If you base your website off of two systems it can make things a lot easy for your customers using two different operating systems.
It also comes in handy with Mac and PC users.
A mac owner will like the interface of their MacBook Pro, but also need the RAM for games if that's what they like to do.
Server virtualisation offers the best from both worlds and is easy to use and understand.
