What is Gartner’s Advice on VMware vSphere Replacement?
According to Gartner’s report, A Guide to Choosing a VMware Alternative in the Wake of Broadcom Acquisition, replacing vSphere with an alternative hypervisor is a tactical option for selecting VMware alternatives, which “provides a balanced approach with good migration and skills applicability and strong long-term viability.” Potential hypervisors include open-source hypervisors, as well as hypervisors sold and supported by specific vendors.
Here, we examine the ten most commonly evaluated hypervisor alternatives for VMware ESXi/vSphere, along with a detailed comparison table to help organizations choose the optimal path forward.
Top 10 VMware vSphere Alternatives in 2026
*The following vendors are listed in alphabetical order, with no ranking implied.
Mainstream Commercial Vendors
Arcfra — AVE
Arcfra is a Singapore-based company aiming to simplify on-premises enterprise cloud infrastructure with their Arcfra Enterprise Cloud Platform (AECP). It offers Arcfra Virtualization Engine (AVE), a native, high-performance hypervisor that forms the compute core of AECP, which can be seamlessly integrated with software-defined storage, networking, management, Kubernetes engine, and other components provided in AECP.
AVE is a KVM-based virtualization. It provides complete VM life cycle management functionalities and advanced capabilities available in vSphere Enterprise Plus (VEP), such as SR-IOV passthrough, distributed switches, GPU passthrough and vGPU, contributing to the platform’s claimed VMware replacement TCO reduction of over 50%.
Citrix — XenServer
Citrix XenServer is a high-performance virtualization platform for graphics-intensive workloads. As the core virtualization for the Citrix Virtual Apps and Desktops (CVAD) ecosystem, it delivers high-performance virtual desktops with exceptional graphics fidelity, strong isolation, and comprehensive NVIDIA vGPU support.
The platform is engineered for VDI-optimized graphics performance. In Gartner’s report “Which VMware Alternatives Are Enterprises Evaluating?”, XenServer is recognized as a less commonly evaluated hypervisor alternative to vSphere.
HPE — Morpheus VM Essentials
As an IT infrastructure vendor originally supporting vSphere and Hyper-V, HPE launched HPE Morpheus VM Essentials (HVM) in early 2025, designed to control both VMware and HVM (KVM-based) environments from a single console.
The platform features per‑socket pricing, HA, live migration, and policy‑driven provisioning, aiming to meet the common demands while reducing TCO. According to Gartner’s report “Which VMware Alternatives Are Enterprises Evaluating?”, concerns with this new offering tend to be about product immaturity and limited support for non-HPE hardware.
Microsoft — Hyper-V
Microsoft’s Hyper-V is a native, enterprise-grade hypervisor deeply integrated into the Windows ecosystem. Embedded in Windows Server and Windows 10/11, it efficiently manages Windows and Linux virtual machines and integrates with the broader Microsoft ecosystem, including Active Directory.
The hypervisor is optimized for Windows Server-intensive workloads and designed to deliver a cost advantage for Microsoft license holders. According to Gartner’s report “Which VMware Alternatives Are Enterprises Evaluating?”, Hyper-V is a most commonly evaluated VMware alternative, but concerns around Microsoft’s investment in the product and the cost of System Center still exist.
Nutanix — AHV
As an HCI vendor, Nutanix provides AHV, a virtualization engine that is tightly integrated with and exclusively available for its Nutanix Cloud Infrastructure (NCI). AHV is a KVM-based virtualization platform that is deeply optimized for the Nutanix stack and managed through the single Prism interface. It can support VMs in the datacenter, at the edge and in public clouds.
Nutanix positions AHV as the default choice for its NCI platform, while clients tend to be concerned about costs that are similar to those of VCF.
Red Hat — OpenShift
Red Hat offers OpenShift — an enterprise-grade Kubernetes platform with integrated virtualization. It provides a comprehensive solution for deploying, scaling, and managing containerized applications, and also includes OpenShift Virtualization, which allows running and managing virtual machines alongside containers on the same platform (built on KubeVirt project)
The platform is engineered for hybrid cloud deployments and container-based transformation. According to Gartner’s report “Which VMware Alternatives Are Enterprises Evaluating?”, concerns arise when OpenShift is not a part of enterprise plans or when clients worry about product and KubeVirt immaturity.
Virtuozzo — Virtuozzo Hybrid Server
As an IT infrastructure vendor focusing on hybrid cloud solutions, Virtuozzo provides Virtuozzo Hybrid Server — a platform designed to deliver high-density virtualization for service providers. It leverages its core system container technology to run hundreds of isolated Linux instances on a single kernel for extreme density, while also unifying support for KVM VMs and software-defined storage.
In Gartner’s report “Which VMware Alternatives Are Enterprises Evaluating?”, Virtuozzo is recognized as a less commonly evaluated alternative to VMware.
Mainstream Open-source Vendors
Oracle — VirtualBox
Oracle offers VirtualBox — an open-source full virtualization software for personal and enterprise use. It functions as a hosted (Type 2) hypervisor, targeted at laptop, desktop, server, and embedded use. It can run multiple operating systems, inside multiple virtual machines (VMs), at the same time.
Notably, VirtualBox is primarily designed for personal development and testing scenarios, and its lightweight nature makes it difficult for large enterprise-grade deployment, such as multi-cloud management and automated operations.
Proxmox — VE
Proxmox VE is an open-source, enterprise-grade server virtualization management platform. It uniquely combines KVM virtualization and LXC container technologies, enabling flexible deployment of both VMs and containers through a single, integrated web interface.
Proxmox VE emerges as a cost-effective and flexible open-source server virtualization platform, making it ideal for SMBs, homelabs, and open-source advocates. Notably, to ensure higher stability and timely troubleshooting, users may need to purchase paid enterprise support subscriptions.
XCP-ng
XCP-ng is a Linux distribution of the Xen Project, building around the Xen Hypervisor and using Xen Orchestra as Web UI. It runs directly on bare metals, providing key virtualization features like VM lifecycle management, HA, live migration, clustering, etc.
As a Xen-based virtualization platform, XCP-ng skills are less common than KVM/Linux and has fewer third-party integrations, making it a less commonly evaluated open-source options compared to Proxmox VE.
More Open-source Options
Enterprises may also evaluate KVM for an open-source VMware alternative. However, KVM is not a turnkey ESXi replacement. Instead, it usually serves as the building blocks of many enterprise-grade virtualization platforms like Proxmox VE, Arcfra AVE, and Nutanix AHV.
