What Is Operating System Virtualization (OS Virtualization)?

TechDogs Avatar

Operating System Virtualization, also known as "OS Virtualization" because of its abbreviated form, is the topic we will discuss today. It is comparable to having a magic box that enables you to simultaneously run different versions of an operating system, such as Windows or Linux, on the same physical machine. It's like you're throwing a party at your house and inviting all of your friends, but each guest brings their unique take on what the house should look like. Virtual machines, or VMs for short, are what is used to refer to each "version of the house." The "magic box" responsible for making all of this possible is known as a hypervisor. The hypervisor serves a similar function to a party planner, ensuring that each virtual machine (VM) has its dedicated virtual resources, such as a CPU, memory, and storage space. In addition, it ensures that each virtual machine operates independently from the others and does not interfere with the functioning of the others. This state is referred to as "isolation." Through the use of OS Virtualization, it is possible to run numerous Virtual Machines (VMs) with various operating systems, including Windows and Linux, on a single physical machine simultaneously. The term for this practice is "multi-tenancy." One further advantage of OS Virtualization is that it enables "live migration" of virtual machines (VMs). Due to this, it is possible to relocate a virtual machine currently running from one physical system to another without experiencing any downtime. It's the same as relocating your good friend's house to a new area while they're still living there, and they have no idea it's even happened! Operating system virtualization, or OS Virtualization, is a technology that enables different operating systems to be run concurrently on the same physical machine by using virtualized resources while maintaining isolation and supporting numerous tenants. Additionally, it enables live migration of virtual machines (VMs). It is similar to possessing a magic box, known as a hypervisor, which enables you to host a party with all your friends, each of whom can bring their version of the house, and you can move them wherever you like.
