Basics of Virtualization
What does Virtualisation mean? The basic definition is ‘that which does not exist physically but is a process, system or computer which will act as a physical system You can operate it as a physical system. In virtualization, the CPU is known as a vCPU, and HDD as a vHDD.
After installing the Operating System (OS) in the virtual environment, the system is then called the VM (Virtual Machine), which accesses the network via the Physical Network Interface Card. VM also has its own Virtual Network Card known as vNIC. In your physical system, you can also install multiple OS with Virtualization. The most important thing to note is that the VM can access all hardware from the main physical machine.
These are the companies which provide the Virtualization technology at server level:
- Microsoft Hyper-V Server 2008 R2
- VMware vSphere 5.0
- Citrix XenServer
- Red Hat Enterprise Virtualization 3
For the Desktop user, and those who want to run Virtual Machines on a desktop or laptop, the providers are:

Cross-platform means you can run the Virtual Box on Intel system and also on AMD based system, no matter what the OS is – Windows Vista, XP, 7 or 8, you can even use RedHat Linux, Solaris, or Mac systems.
