What is a hypervisor?
A hypervisor is a virtualization operating system that allows you to create virtual machines. With virtual machines, you can not only run traditional operating systems, but you can use virtual machines to host modern applications based on Linux container workloads with all the features you would expect with modern capabilities.
If you want to get into running a home lab, you could certainly load a single operating system on your home server to play around with different technologies. However, you can only test a single operating system at a time with a single set of hardware.
By installing a hypervisor on your bare metal hardware instead, you can run many different workloads (operating systems running in VMs) on the same set of hardware.
Type-1 vs Type-2 Hypervisors
When considering virtualization platforms for your home lab, you may have come across terms like “Type-1” and “Type-2” hypervisors. But what do they mean, and how do they impact your choice of hypervisor? Let’s delve into this comparison.
What are Type-1 Hypervisors?
Often referred to as “bare-metal” hypervisors, you run type-1 hypervisors directly on the system’s hardware. They have direct access to the hardware resources and thus offer high performance and efficiency. Examples of type-1 hypervisors include VMware ESXi, Microsoft Hyper-V, KVM, and Xen Project.
Type-1 hypervisors are typically used in enterprise server environments because they can handle high workloads and deliver high performance. However, they can also be advantageous in a home lab setting, especially if you plan on running numerous or resource-intensive virtual machines.
What are Type-2 Hypervisors?
On the other hand, type-2 hypervisors, also known as “hosted” hypervisors, operate on a host operating system that manages the hardware. Examples include VMware Workstation, Oracle VM VirtualBox, and Parallels Desktop.
Type-2 hypervisors are generally easier to install and use since they operate like any other application on your host OS. For those starting their journey into virtualization or running a small-scale home lab on existing hardware, a type-2 hypervisor may be a good choice.
So, Which is Better for My Home Lab?
The decision between Type-1 and Type-2 hypervisors for your home lab largely depends on your specific requirements and resources. If you have dedicated hardware for your home lab and require high performance or plan to run a large number of virtual machines, a Type-1 hypervisor like VMware’s ESXi or KVM Hypervisor may be your best bet.
On the other hand, if you’re starting or want to run a small home lab on your existing PC or mini PC, a Type-2 hypervisor such as VMware Workstation or Oracle VM VirtualBox could be a more practical choice to get started.
Part 1: Open-Source Hypervisors
These are listed in no particular order of precedence. These are the hypervisors that I consider to be the best of the open-source variety. These have great capabilities and features and stand out for use in the home lab.
Xen Project, an open-source type-1 hypervisor, is an excellent choice for your home lab environment. It’s a lightweight hypervisor that supports a variety of operating systems. Xen enables you to run multiple operating systems concurrently.
The Xen Project, backed by Linux, comes with strong command-line support and Xen Orchestra, a web interface that enhances usability. It is a free download as a binary for Linux.
Visit the official site for the Xen Project here for more information and to download: Home – Xen Project.
Proxmox VE stands as another robust open-source type-1 hypervisor in the market. Its strength lies in its ability to manage both virtual machines (VMs) and Linux containers, offering flexibility for various platforms. Its popularity has exploded and it seems like everyone is running Proxmox VE in their home labs these days.
Proxmox VE supports clustering, nested virtualization, and live migration, enabling seamless transitions between different hardware in your home lab. It also offers a free backup solution called Proxmox Backup making it even more attractive to have unlimited backups of your workloads.

KVM (Kernel-based Virtual Machine) is a Linux-based type-1 open-source hypervisor. It allows you to run multiple operating systems concurrently, like the other options mentioned.
This feature greatly benefits your home lab, which might host various workloads. Debian Linux, among other operating systems, can be installed, providing a wide range of options. You can easily download Ubuntu Server for free and then install KVM in Ubuntu to start hosting your virtualized home lab. KVM is the more vanilla offerings in the list from a management perspective. There are tools available, but the tools are not as good in my opinion as those with Proxmox and Xen/XCP-ng.
Part 2: Paid Enterprise Hypervisors
VMware vSphere is my preferred solution in the enterprise space and the home lab (with VMUG, explained below) if you want to run an enterprise hypervisor.
VMware ESXi (VMware vSphere)
Stepping into the realm of paid hypervisors, VMware ESXi is a market leader. It is specifically designed for enterprise-level applications but can be scaled to the size you need to suit a home lab environment.
Its broad range of features, high performance, and extensive hardware support make it an excellent choice. VMware ESXi is part of VMware’s vSphere suite, which has many management tools for your VMs. These include an HTML5 web interface built into ESXi and also the very extensive vSphere Client found in vCenter Server.
If you decide to run ESXi, there is the VMUG Advantage subscription which I have mentioned before as arguably the most cost-effective purchase you can make if you want to run a home lab. It gives you access to basically the entire VMware catalog of solutions for $199 a year or so. You can always find coupon codes as well for 10% or more off that price.

I also like Hyper-V, and it is a great solution, especially for those deeply invested in the Microsoft ecosystem. Microsoft Hyper-V is a Windows server-based type-1 hypervisor with Windows Server.
The new Windows Admin Center is a really great new tool to manage your Hyper-V role-enabled servers in the data center or home lab.
Hyper-V supports multiple operating systems, making it a versatile choice for your home lab. Despite being a paid option (needs Windows licensing and “Pro” edition for client OS’es for client Hyper-V), its cost can be justified by its extensive features, such as file sharing, network interface configuration, and easy VM deployment.
One thing I will say about Hyper-V is that it “feels” like Microsoft is not investing a lot of time or new features into Hyper-V as they are enticing everyone to the cloud. Hyper-V Server 2019 is the last free Hyper-V Server and there is not a Hyper-V 2022 option (talking about the free Hyper-V Server offering and not the role that is found in Windows Server 2022).
As you delve into hypervisors, Nutanix AHV certainly merits attention. AHV, standing for Acropolis Hypervisor, is a part of the Nutanix Acropolis platform, an enterprise-level cloud computing service.
AHV is a Type-1, KVM-based hypervisor that offers a high-performance virtualization solution. Specifically designed to streamline data center operations, AHV combines virtualization and storage management capabilities in one software package.
One key feature of AHV is its simplicity. It integrates well with the Nutanix platform, creating an environment that simplifies virtual machines’ setup, management, and scaling. It offers an intuitive interface that helps create, manage, and delete virtual machines.
