Operating System Virtualization: What is it?

Operating System Virtualization (OS Virtualization) is the last type of Virtualization in Cloud Computing. Operating system virtualization is a part of virtualization technology and is a type of server virtualization. In this OS Virtualization tutorial, we are going to cover the uses, working, types, types of disks, and advantages of Operating System Virtualization.

What is Operating System Virtualization?

Operating System Virtualization (OS virtualization) refers to the modification of a standard OS allowing multiple users to run different applications on a single computer at a time. This concept of virtualization is useful for the secure allocation of a finite number of hardware resources among several users and is commonly used in virtual hosting environments.

OS virtualization is also used to integrate server hardware by moving services onto separate hosts. OS virtualization services offer greater flexibility and reduced overhead by facilitating granular migration of individual applications. In addition, the separation of applications into different containers ensures enhanced security.

How does OS Virtualization work?

Operating System Virtualization runs with the help of a virtual disk, and it does not require any physical disks or any type of local storage. It can get directly connected by using any medium to a centralized server that transmits the data with a virtual disk.

But before transmitting to the same customer who acts as an end-user, the Operating System will be loaded into the System, and the booting procedure initiated.

Finally, the data will be virtualized, and the customer will receive its data with the help of the desired network.

Types of Operating System Virtualization

There are two types of Virtualization in OS:

  • Windows Operating System Virtualization – In this virtualization, you have to install VMware Workstation Software in the first place. Then you can install Windows Software virtually.
  • Linux Operating System Virtualization – You have to install VMware software in the first place to install any software. OS Virtualization requires installing VMware software in the first place to virtualize the Linux Operating System as well.

Also, OS Virtualization in cloud computing works via two virtual disks. Therefore, the client will be able to connect to that disk through the network.

  • Shared Disk – Multiple companies/clients can use the shared disk at a time. The change created by the companies applies separately and clears the cache. Other clients’ settings will not be affected after the restarting of this system. The system sets as default after the restarting process.
  • Private Disk – A single company/client can use a private Disk. The client/company stores the information that is based on assigned capacity.

Advantages of OS Virtualization

Following are the benefits of Operating System Virtualizations, let’s discuss them one by one:

  • Operating system virtualizations eliminate the use of physical space utilized by the IT system. As everything is virtual it will require less space and hence it will save money.
  • As there is no hardware required the maintenance will be less and therefore it will save both time and money.
  • The number of Machines will be late so there will be lower power consumption, lower cooling requirements, low maintenance, and more electricity savings.
  • It also allows the companies to make enhancements in terms of efficiency to use the server hardware and thus there is a greater return on investment (ROI) on the purchase and greater operational works.
  • OS Virtualizations have quick deployment capability and in the traditional environment in the traditional deployment, every machine needs to load individually which is not a problem in OS Virtualization.

Uses of OS Virtualization

  • OS Virtualization is used in Virtual Hosting Environment.
  • It is used for the secure allocation of finite hardware resources among several unknown and distrusting users.
  • The system administrator utilizes it to integrate server hardware by transferring services to a separate host.
  • It will boost security by separating multiple applications into various containers.
  • OS Virtualization does not depend on Hardware Virtualization to work efficiently.


Operating system virtualization eliminates endpoint security problems, protects sensitive information, and ensures reliable performance. With OS virtualization, end-users can get their job done without security constraints and without having to worry about compromising sensitive data.

Today, many companies provide a wide range of security solutions with the help of OS virtualization technology and their applications to the endpoints. Business, enterprise, and private cloud service providers also use such technologies to provide efficient and reliable services.

There is no denying that a practical and well-planned combination of virtual machines helps to maximize digital security. As every virtual machine has some limitations, organizations and IT departments need to implement different operating system virtualization technologies to benefit from modern security measures.
