Proxmox VE has not appeared overnight. It has been present for years in labs, hosting providers, small and medium technical companies, universities, and enterprise environments seeking an open, flexible virtualization platform without per-core licensing. What has changed is the context: since Broadcom completed its acquisition of VMware in November 2023, many organizations have started to re-evaluate their virtualization costs.
The phrase “Proxmox does the same as VMware for free” works well as a viral headline, but it needs nuances. Proxmox VE covers many functions traditionally associated with mature enterprise platforms: virtual machines with KVM, LXC containers, clustering, high availability, live migration, Ceph integration, snapshots, backups, and a fairly comprehensive web interface. However, operating a critical platform is never free: hardware, storage, networking, backups, support, internal expertise, migration, and daily operations all entail costs.
The VMware bill has accelerated the conversation
Broadcom’s acquisition of VMware marked the end of a long chapter in enterprise virtualization history. VMware remains a very mature platform with a large ecosystem, extensive installed base, and tools that have supported critical workloads for years. The challenge for many customers is not only technical but also economic and contractual.
Post-acquisition, Broadcom reorganized VMware’s offerings and reinforced its subscription model, emphasizing packages like VMware Cloud Foundation and VMware vSphere Foundation. This shift has caused tension among clients, partners, and cloud providers. In the case of AT&T, legal documents revealed that Broadcom proposed a 1,050% increase in certain VMware-related costs.
The dissatisfaction is not limited to a single client. Tesco also took Broadcom to UK courts over license and support changes related to VMware, affecting tens of thousands of server workloads. This dispute, still ongoing through legal proceedings and company responses, reflects a broader reality: virtualization has transitioned from a purely technical decision to a matter of strategic dependency.
Against this backdrop, Proxmox VE gains visibility by offering a different approach. The software is available as open source, without per-core licensing, and its business model is based on support subscriptions per physical socket. According to Proxmox, these subscriptions provide access to the Enterprise repository and support services, with plans starting at €120 per year per socket for Community and up to €1,100 per year per socket for Premium.
| Aspect | VMware by Broadcom | Proxmox VE |
|---|---|---|
| Main model | Commercial subscription and packages like VCF/VVF | Open source software with optional support subscriptions |
| Cost metrics | Package, cores, and contractual minimums per product | Per physical socket for support; no per-core license to run the platform |
| Base license cost | Commercial, contract and edition dependent | No license cost to install and run Proxmox VE |
| Enterprise support | Included in VMware’s commercial model | Available via Proxmox or partners’ subscriptions |
| Virtualization technology | ESXi/vSphere | KVM for VMs and LXC for containers |
| High availability | Yes, with mature VMware ecosystem tools | Yes, integrated into Proxmox VE clusters |
| Live migration | Yes | Yes |
| Shared storage | vSAN and other VMware options | Integrated Ceph, plus ZFS, NFS, iSCSI, others |
| Management tools | vCenter and associated tools | Web interface and API |
| Typical use cases | Large environments with strong VMware dependencies, VCF, NSX, vSAN or certified integrations | SMBs, cloud providers, technical environments, private cloud, labs, and organizations seeking less licensing dependence |
Proxmox VE 9.2 strengthens cluster and SDN features
Released on May 21, 2026, Proxmox VE 9.2 confirms that the project is more than just a low-cost alternative for small setups. The update introduces a Dynamic Load Balancer to improve cluster load distribution, expands the software-defined networking layer with native support for WireGuard and BGP, adds BGP/EVPN filtering with route maps and prefix lists, and enables management of custom CPU models directly from the web interface.
It also adds functionalities aimed at real-world operations, such as the ability to enable and disable high availability management during maintenance windows. While less headline-grabbing than cost-related announcements, this improvement is highly relevant for administrators managing production clusters and wanting to avoid unintended disruptions during planned tasks.
The underlying technology also matters. Proxmox VE 9.2 now runs on Debian 13.5 “Trixie”, Linux kernel 7.0, QEMU 11.0, LXC 7.0, and ZFS 2.4, with Ceph Tentacle 20.2 as a stable option alongside Ceph Squid 19.2. This detail is crucial for cloud providers: Proxmox positions itself not only as a hypervisor but as a comprehensive virtualization and hyperconverged infrastructure stack.
Cost savings don’t eliminate the need for migration planning
Migrating from VMware to Proxmox should not be approached impulsively as a way to “stop paying”. While it can be economically sensible, migration requires inventory, testing, backup review, network analysis, OS compatibility checks, downtime planning, monitoring integration, security policies, and a clear rollback plan.
It’s also important to assess which parts of the VMware ecosystem are genuinely in use. A company only needing basic VM deployment, minimal high availability, live migration, and shared storage will have a different analysis than one relying on NSX, vSAN, advanced automation, integrations with corporate tools, or certified workflows around vCenter.
Proxmox VE is particularly suitable when organizations want to regain control over their infrastructure, reduce licensing change exposure, leverage existing hardware, or build private clouds with open-source stacks. Conversely, it may not always be the fastest option for organizations with thousands of workloads, highly specialized VMware teams, or complex enterprise contracts.
The core issue is not whether VMware “is dead” or whether Proxmox “does everything for free”. VMware remains a reference platform for many companies. Meanwhile, Proxmox VE is becoming an increasingly serious alternative for those seeking a different balance of cost, control, and technical capability.
Virtualization thus enters a less comfortable phase for IT departments. For years, many firms renewed VMware licenses almost out of inertia. Now, every euro, dependency, and contract must be justified. In this shift, Proxmox VE has a clear advantage: it forces a comparison based on real numbers.
Frequently Asked Questions
Is Proxmox VE really free?
Proxmox VE can be downloaded, installed, and used without a license fee. In production environments, it’s common to consider a support subscription for access to the Enterprise repository, stable updates, and support services.
Does Proxmox VE always replace VMware?
Not always. It can substitute many virtualization use cases, but the decision depends on integrations, associated tools, environment size, required support, and reliance on specific VMware features.
What does Proxmox VE 9.2 add?
The 9.2 version introduces Dynamic Load Balancer, SDN improvements with WireGuard and BGP, BGP/EVPN filtering, management of CPU models from the web interface, and enhancements for high availability maintenance.
What should a company review before migrating from VMware?
They should check their virtual machine inventory, networking, storage, backups, OS licensing, application dependencies, monitoring, security, support plans, and have a rollback strategy.
