Exploring VMware Alternatives: Proxmox, OpenStack & KubeVirt

Virtualization in 2025: making the right choice between Proxmox, Kubernetes & OpenStack

With the shifting virtualization landscape, many among you are evaluating open source alternatives to VMware. In today’s IT landscape, the pressure to modernise infrastructure is immense, especially with license costs climbing and companies seeking greater control and flexibility. 

Whether you’re managing a compact lab setup or a sprawling data center, the virtualization platform you choose could make or break your operations. Especially when your are transitioning from proprietary hypervisors like VMware.

Let’s cut through the clutter and break down 3 powerful open source solutions: Proxmox, Kubernetes with KubeVirt, and OpenStack. At OPEN'25, Jochen Maes, showed us the pro's and con's of the following solutions:

Red Hat OpenShift Virtualization

One of the discussed solutions in our battle card is KubeVirt which can be distributed with Red Hat OpenShift Virtualization Engine, Suse Harvester, ...

KubeVirt is an open source project that makes it possible to run, deploy, and manage virtual machines (VMs) with Kubernetes as the underlying orchestration platform. Virtual machines behave the same way they would in a traditional virtualization environment, but they can run on the same platform as containerized microservices and cloud-native applications.
