The Rise of Linux with the KVM hypervisor

KVM-based core virtualization infrastructure is made possible by the Linux kernel. The Linux kernel has evolved to support a wide range of virtualization software and new hardware features like hybrid CPU cores running in the new Intel “big little” architecture. 

The integration of the KVM hypervisor with the Linux kernel provides efficient computer resource management and enables businesses and home labbers to use multiple cores and computing resources for their virtual machine software. It also helps secure virtual containers for their operations.

I think KVM is set to rise in 2024 with organizations looking at their options and seeing what is available for use with VMware licensing changes and other considerations.

Key Virtualization Workloads Supported by KVM Hypervisors

KVM hypervisors are known for their ability to run key virtualization workloads and apps, including those requiring high performance and scalability. 

It leverages hardware virtualization extensions and implements efficient load balancing and processor scheduling. KVM-based solutions enable running multiple operating systems with minimal overhead and loss of performance.

An organization who makes the decision to run KVM will find it will run anything and everything they need to throw at it in terms of virtual machines. It lays the foundation and has the capability to run containerized workloads

Managing KVM Hypervisors

Centralized management is an important consideration for KVM hypervisor platforms. Effective management tools is one of the reasons VMware vSphere has been so successful. It enables administrators to manage multiple virtual machines, allocate resources, and monitor system performance. 

Platforms like Nutanix, Red Hat Virtualization, Proxmox, and others, provide advanced system management features and tools that simplify day-to-day operations. I think the management features of these KVM variants will help to make them stand out as choices for the best KVM-based hypervisors in 2024.

Wrapping up the best KVM hypervisors in 2024

I think many are looking at the hypervisor landscape in 2024, especially VMware customers. When it comes to a virtualization platform that supports key virtualization workloads like Windows Server, Linux, and containers in production, KVM-based hypervisors are a great choice. 

When we look at the sheer number of solutions that are running on KVM underneath the hood, the choices are many for running virtual operating systems. However, there are many considerations to be made and factors to look at. For example, customers want to look at which solution closely matches their use cases, development, innovation of product, device support, app demands, money and budget considerations, compatibility, and automation processes capabilities with standard tools like Ansible, Chef, and others for provisioning tasks. 

A company may also have interest in the creation of VDI environments to replace desktops with PC replacement virtual machines. There are many options that may support the operation of critical processes. However, there are also other hypervisors out there based on the Citrix hypervisor, Oracle, and other distributions that may also be considered for testing and production environments.

  1. LXD is missing from your list. It’s not just a cli on top of LXC.

    It’s a distributed/clustered virtualization system which supports both containers as well as VMs.

    The biggest “con” is that it doesn’t have any UI (yet; Canonical is actively working on one).

    You might want to give it a more in-depth review.

    1. Freebsd with vm-bhyve, it’s the fastest, most secure, and native zfs for all your VMs. I can zfs rollback any VM I want, run wireguard, firewall, bind, dhcpd etc.

      Mostly I toss home assistant in VM, but I have barebones server to run CUDA and AI as well. Can’t really beat it.

    1. Miguel,

      Thank you for the comment. I was centering around OS’es that are purpose built for virtualization. I agree Kubevirt and Openshift are great and I have written about them. Here we are highlighting mainly hypervisors that are built for this purpose and not as much Kubernetes based virtualization.


  2. Você pode me ajudar a descobrir qual seria o melhor otimizado para um servidor de virtualização para games na nuvem?

  3. Red Hat OpenShift with the free OpenShift Virtualization operator add-on, and Red Hat Enteprise Linux (RHEL) KVM, are both missing from your list. Both have free trials available plus we have free Red Hat subs available through our developer program, free to sign up at (scroll down to free Developer membership benefits and how to sign up). OpenShift Virtualization is 100% RHEL KVM under the hood and utilizes the CNCF project kubevirt to provide containers *AND* VMs in one enterprise class platform.

    1. Michael,

      I really appreciate your comment and insights. I didn’t realize you can have free developer membership benefits and the ability to use Red Hat OpenShift. I will dig into this and create some content along those lines of the steps, and experiences.

      Thanks again Michael,
