What is KVM Virtualization and what is it good for?

Virtualization is a technology that allows you to run multiple operating systems on a single server. You can think of it as partitioning a large physical server into smaller virtual machines that each run their own instance of an operating system.

In addition to reducing hardware costs, virtualization offers flexibility and ease-of-use by allowing the administrator to move virtual machines between hosts without downtime or data loss. This article will explain what kernel-based Virtual Machine (KVM) is, how it works, and when you might want to use it for your business needs

KVM is a modern day virtualization technology which stands for Kernel-based Virtual Machine. It is a full virtualization solution for Linux on X86 hardware containing virtualization extensions (Intel VT or AMD-V).

KVM stands for Kernel-based Virtual Machine. It is a modern day virtualization technology which is also known as Kernel-based Virtual Machine. KVM is a full virtualization solution for Linux on X86 hardware containing virtualization extensions (Intel VT or AMD-V).

KVM works on the concept of Type 1 Hypervisor, where all of the hardware resources are allocated to the guest operating system during its setup and run time. By using this process, it gives users the ability to host multiple VMs on one physical server at the same time without affecting each other's performance in any way.

Modern Virtualization techniques allow us to emulate almost any operating system on top of the host operating system and KVM is one such type 1 hypervisor which utilizes this technique to virtualize guest machines.

The type 1 hypervisor is a virtual machine monitor that runs directly on top of the host operating system. The most popular examples of type 1 hypervisors are VMware Workstation and Oracle VM VirtualBox, but they can also be found in many other products. In this type of hypervisor model, each virtual machine has its own operating system running on top of the host operating system (OS). The guest OS has no knowledge that it is not running natively on physical hardware.

The Type 2 Hypervisor is different from a Type 1 Hypervisor since it runs as an application on top of another OS, called the Host OS. This means that there are two separate entities: one is your host computer and second one is your virtualization software which handles all virtualized machines you create within itself.

This way both types offer their own advantages/disadvantages depending upon how you're going to use them - whether as standalone systems or as part of larger solutions involving multiple servers connected together via LAN networks where each node would need its own dedicated hardware set up with proper networking facilities like firewalls etc.,

The KVM project was started in 2006 when Red Hat developer, Avi Kivity, used QEMU (an open source machine emulator) to create a virtual machine monitor that runs directly on top of the Linux kernel.

KVM is a full virtualization solution for Linux on X86 hardware and includes a complete set of features:

  • Virtualization extensions (Intel VT or AMD-V)

  • Kernel-based virtual machine monitor, which runs directly in the host kernel's memory space

  • Kernel modules required for KVM to work (QEMU, kvmtool)

Virtualization extensions are not required for KVM to function. The host operating system can run without them if it doesn't support them. However, you'll need virtualization extensions to use KVM's full capabilities including nested paging and shared memory access.

  • Kernel-based Virtual Machine (KVM) is a popular and open source full virtualization solution for Linux servers.

  • Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux servers. KVM uses the QEMU emulator and hardware-assisted virtualization to run virtual machines on the host operating system.

  • Kernel-based Virtual Machine (KVM) is an open source full virtualization solution for Linux servers. KVM supports migration of running VMs, dynamic adjustment of resources assigned to VMs, live snapshots, live cloning, and Intel VT/AMD RVI (Rapid Virtualization Indexing).

Conclusion

By now, we should have learned a thing or two about KVM virtualization and its importance. As you can see, it is one of the most popular ways to get started with virtualization on Linux servers. KVM supports most of today's hardware architectures and has an active community behind it which makes it a great choice for novice as well as experienced users who want to get their hands dirty with virtual machines.
