Years back, I used to be a mainframe systems programmer (Dinosaur), working with large scale IBM machines and operating systems.
At that time, there was an opsys called VM/370 (Virtual machine/370)
The idea of it was to be able to run more than one opsys under one physical machine
Years years later, this thing was introduced in the PC world, and the word (Virtualization) becomes more and more popular
My first experince was with a product called (VMware), when i read an article about it in some computer magazine
but after that, few other products start showing in the scene and in the market, some are paid, some are free
so, Which virtualization software do you use? and which one do you prefer more, and why?
Thank you
