Today instead of an “Operation” we will do a more normal Blog post and the topic is Virtualization. So what does Virtualization mean? Well first something that is Virtual is like the real thing but not quite. Like a reproduction of a famous painting it’s not the original but still looks good. Another term you hear associated with Virtualization is Virtual Machine . A Virtual Machine is a Virtual computer. It’s not what you see next to your desk and you don’t have a physical way to turn on a Virtual Machine. A Virtual Machine is like any other program you have on your computer. Â Like any program you double click an icon on your desktop and VoilÃ a virtual computer starts running within your computer. In the window that pops up after you double click the Virtual Machine you will see a computer booting up, just like when you start your real computer!
So why on earth would I want a Virtual Computer when I have the real thing?
Advantages of Virtual:
- You can have many different computers on one computer. Â More specifically you can have many different Operating Systems running on one computer. Â So if you want to try out MacintoshÂ® but your physical computer is a WindowsÂ® machine you can install a virtual MacintoshÂ® to try it out!
- Virtual Backups are easier than a real computer backup. Â To backup a Virtual Machine is as easy as backing up a File.
- Portability;Â once you backup your virtual machine to a file you can then take your virtual machine backup file and go run it on your friend’s computer. Â Every thing you keep in the virtual computer will be accessible!
Disadvantages of Virtual:
- Virtual computers aren’t as fast as real computers. Â Because the virtualzation program has to make a virtual home for your new Virtual computer (Virtual Machine) it takes away some of the computer’s raw power. Â This is particularly noticed in resource intensive tasks like playing a video game.
- Vendor Lock in. Â Your Virtual Computer will only run on one Virtualization software package. Â So if you want to share your computer with a friend they would have to install the same Virtualization Software. Â The good news is there are many free Virtualization software packages.
I want to play with Virtualization, where do I get started? Â (We have experience with the first two only):
