Hyper-V vs Proxmox: Which Virtualisation Platform is Right for You?

Budget pressures, changing licensing models, and the rise of hybrid cloud architectures means IT teams are reconsidering their virtualisation tech.

Do the traditional choices still make sense for modern firms? Or is it time to shake things up?

In this comparison, we’ll examine Hyper-V and Proxmox VE; two virtualisation platforms that take distinctly different approaches to the same fundamental challenge.

We’ll explore their architectures, compare their features, and help you understand which platform aligns best with your organisation’s requirements.

Microsoft Hyper-V is a native hypervisor that’s been part of the Windows Server family since 2008. It’s Microsoft’s answer to enterprise virtualisation, deeply integrated with the Windows ecosystem and designed to work nicely with other Microsoft technologies.

It’s worth noting that Microsoft has deprecated the free standalone Hyper-V Server as of 2022, meaning most new deployments will use Windows Server as the host or consider Azure Stack HCI for hybrid scenarios. This change reinforces Microsoft’s push towards integrated solutions rather than standalone hypervisors. With Windows Server 2025, Hyper-V continues to evolve, offering enhanced capabilities for modern workloads.

For businesses using Microsoft 365, Active Directory, and other Microsoft services, Hyper-V is a natural extension of their existing infrastructure, with PowerShell automation and Windows Admin Center giving you those familiar management tools.

Proxmox Virtual Environment (Proxmox VE) is an open-source virtualisation management platform that combines KVM (Kernel-based Virtual Machine) for full virtualisation with LXC (Linux Containers) for lightweight container-based virtualisation.

Sounds complicated, but Proxmox is really all about the simplicity.

Built on Debian Linux, it gives you enterprise-class features through a web-based management interface.

Rather than overwhelming administrators with complex licensing tiers or feature restrictions, Proxmox provides all functionality out of the box. Whether you need high availability, live migration, or software-defined storage, it’s all included from day one.

With the release of Proxmox VE 9.0, the platform continues to evolve with improved virtualisation capabilities and modern hardware support. It can run both traditional VMs and lightweight containers on the same platform, so it’s great for modern, mixed workloads.

Management and automation

Hyper-V management centres on Windows tools. Windows Admin Center provides a modern web interface, whilst System Center Virtual Machine Manager (additional cost) offers enterprise-scale management. PowerShell remains the automation powerhouse, with comprehensive cmdlets for every aspect of Hyper-V management. This PowerShell integration makes for some sophisticated automation but needs Windows-specific scripting knowledge.

Proxmox takes a web-first approach with its responsive interface handling most daily tasks. The command-line interface uses standard Linux tools plus Proxmox-specific commands. The RESTful API enables automation using any programming language, not just PowerShell. Whilst perhaps lacking some enterprise management features, Proxmox’s approach is refreshingly straightforward for common operations.

Azure integration and hybrid cloud

Hyper-V provides the smoothest path to Azure. Azure Site Recovery can replicate Hyper-V VMs for disaster recovery, Azure Backup protects your data, and Azure Arc brings cloud management to on-premises infrastructure. The new Azure Stack HCI represents Microsoft’s vision for hybrid infrastructure, essentially running Azure services on your hardware.

Proxmox lacks native Azure integration, requiring more planning for cloud migrations. VMs need converting to Azure-compatible formats, and there’s no built-in disaster recovery to Azure.

That said, this limitation can encourage more thoughtful cloud adoption, considering which workloads truly benefit from cloud hosting versus simply replicating on-premises infrastructure in Azure.

For organisations committed to Azure, Hyper-V does have clear advantages. But if you’re taking a multi-cloud or cloud-agnostic approach, Proxmox’s independence might actually be preferable.

Architecture and integration

Hyper-V runs as a Type 1 hypervisor, deeply integrated with Windows Server. This tight integration provides strong compatibility with Microsoft’s ecosystem, though it ties you to Windows-based management. Clustering and high availability come through Windows Failover Clustering, which can be complex to configure.

Proxmox VE builds on Linux’s KVM hypervisor with a Debian base. It offers built-in clustering for up to 32 nodes with straightforward HA setup through the web interface. The platform uniquely combines traditional VMs with LXC containers, providing flexibility for mixed workloads.

Cost structure

Hyper-V requires Windows Server licensing since the free version was deprecated. Standard edition starts around £900, whilst Datacenter (needed for unlimited VMs) costs £6,000-7,000 per host. Add license costs for users, and costs mount quickly.

Proxmox is completely free and open-source with all features included. Optional support runs €115 per socket annually; a fraction of Windows Server costs. Many organisations run production workloads without paid support.

Performance capabilities

Hyper-V excels with Windows workloads, supporting massive scale in Windows Server 2025 (up to 2,048 vCPUs and 240TB RAM per host). Dynamic memory and live migration keep things running smoothly.

Proxmox delivers near-native performance, especially for Linux guests. LXC containers are said to achieve 95-99% bare-metal performance with minimal overhead. While Windows VMs run well, they lack Hyper-V’s deep optimisations.

Security features

Hyper-V makes use of Windows Server’s security framework, including Shielded VMs, BitLocker integration, and Active Directory authentication. Enterprise security features come built-in, particularly in the Datacenter edition.

Proxmox provides solid Linux-based security with role-based access control, two-factor authentication, and flexible firewall rules. The open-source nature allows auditing, though advanced features like VM encryption need manual configuration.

Storage options

Hyper-V supports local storage, SMB shares, iSCSI, and FC SANs. Storage Spaces Direct enables software-defined storage, whilst VHDX format handles disks up to 64TB.

Proxmox has a lot of flexibility: local options (LVM, ZFS), network storage (NFS, iSCSI), and distributed systems (Ceph, GlusterFS). ZFS integration provides snapshots and compression without additional licensing.

Networking capabilities

Hyper-V includes virtual switches with VLAN support and NIC teaming. Advanced SDN features need additional components and know-how.

Proxmox uses Linux bridges and Open vSwitch for solid networking. While lacking Hyper-V’s SDN capabilities, the mature Linux networking stack handles most requirements well.

Hyper-V makes perfect sense if you’re already living in Microsoft’s world. It’s the path of least resistance for Windows-centric organisations, though that convenience does come with typical Microsoft complexity and costs.

Pros

1. Superb Windows integration: If you’re running Windows workloads, Hyper-V offers unmatched integration with Active Directory, Windows Admin Center, and the broader Microsoft ecosystem.
2. PowerShell automation: Comprehensive PowerShell cmdlets enable powerful automation and scripting, perfect for Windows administrators who already know PowerShell.
3. Included with Windows Server: If you’re already licensing Windows Server for other purposes, Hyper-V comes along for the ride at no extra cost. Standard edition includes rights for 2 VMs, whilst Datacenter offers unlimited virtualisation.
4. Azure integration: Natural progression to Azure with Azure Site Recovery, Azure Backup, and straightforward hybrid cloud scenarios through Azure Arc. Azure Stack HCI provides a modern hybrid infrastructure option.
5. Familiar management tools: Windows administrators can use tools they already know, reducing the learning curve significantly. Windows Admin Center provides a modern management experience.
6. Enterprise scale: With support for up to 2,048 vCPUs and 240TB RAM per host in Windows Server 2025, Hyper-V can handle the largest enterprise workloads.

Cons

1. Windows-centric limitations: Whilst Linux VMs run adequately, Hyper-V clearly favours Windows workloads, with Linux guests missing some optimisations.
2. Licensing complexity: Understanding what features are available in which Windows Server edition can be mind-bending, and costs escalate quickly with Datacenter edition now exceeding £6,000 per host.
3. Resource overhead: Running full Windows Server for management adds significant overhead compared to lightweight hypervisors. The parent partition typically needs 2-4GB RAM minimum.
4. Limited container support: Whilst Windows containers are supported, they’re not recommended for large-scale Linux container workloads—Proxmox or dedicated container platforms are better choices.
5. Cluster complexity: Setting up failover clustering requires serious Windows expertise and specific infrastructure requirements, including shared storage and multiple network adapters.
6. Deprecated free option: The removal of free Hyper-V Server means organisations must now invest in Windows Server licensing from the start.

Proxmox has some refreshing simplicity in a world of complex enterprise software. It’s not trying to be everything to everyone, but what it does, it does well, without the licensing headaches.

Pros

1. Unbeatable value: All features included for free, with optional affordable support. You could run a full cluster with HA and live migration without spending a penny on licensing.
2. Container excellence: Native LXC support means you can run lightweight Linux containers alongside full VMs; perfect for microservices and development environments. Unlike Hyper-V’s limited container support, Proxmox was built with containers in mind.
3. Storage flexibility: From local ZFS to distributed Ceph, Proxmox supports diverse storage options without additional licensing or restrictions.
4. Straightforward clustering: Setting up a cluster takes minutes, not hours, with high availability that actually works without extensive prerequisites.
5. Active development: Regular updates and an engaged community mean Proxmox continues to evolve with modern infrastructure needs.
6. No vendor lock-in: Open-source nature means you’re never held hostage by licensing changes or forced upgrades.

Cons

1. Linux expertise required: When things go wrong, you’ll need solid Linux troubleshooting skills to dig into issues.
2. Limited Windows optimisation: Windows VMs run fine, but you won’t get the same level of integration and performance as with Hyper-V.
3. Smaller ecosystem: Fewer enterprise tools directly support Proxmox, potentially requiring workarounds or agent-based solutions.
4. Enterprise feature gaps: Advanced SDN, sophisticated disaster recovery, and some enterprise storage features aren’t as developed as commercial alternatives.
5. Support concerns: Whilst community support is good, enterprise support options are limited compared to Microsoft’s global support infrastructure.
6. Perception issues: Some enterprises view Proxmox as “not enterprise-ready” despite evidence to the contrary, which can be a political challenge.

Windows-dominated environments are Hyper-V’s natural territory. When you’re running Active Directory, Exchange, SharePoint, and SQL Server, Hyper-V’s deep Windows integration provides tangible benefits. Features like domain joining, Windows Update integration, and PowerShell Direct make managing Windows VMs remarkably straightforward.

Organisations with existing Microsoft agreements often find Hyper-V economically attractive. If you’re already paying for Windows Server Datacenter licences or have an Enterprise Agreement, adding Hyper-V costs nothing extra. This makes it particularly appealing for businesses already invested in the Microsoft ecosystem.

Azure hybrid deployments benefit from Hyper-V’s position as Azure’s underlying technology. Using Hyper-V on-premises simplifies hybrid scenarios with Azure Site Recovery for disaster recovery, Azure Backup for data protection, and Azure Arc for unified management. The consistency between on-premises and cloud environments reduces complexity.

Virtual desktop infrastructure (VDI) projects work well with Hyper-V’s DDA or GPU-P and Remote Desktop Services integration. For organisations needing to provide Windows desktops to remote workers or thin clients, Hyper-V offers a complete, integrated solution.

Small to medium Windows teams with limited IT resources appreciate Hyper-V’s familiar Windows management. If your team already knows Windows Server, adding virtualisation doesn’t require learning an entirely new platform. Windows Admin Center provides a modern, browser-based interface that’s approachable for generalist IT staff.

Mixed operating system environments showcase Proxmox’s versatility. When you’re running Linux web servers, Windows application servers, and containerised microservices, Proxmox handles them all competently. The platform doesn’t favour one OS over another (beyond natural Linux optimisations), making it ideal for heterogeneous environments.

Budget-conscious organisations find Proxmox’s cost attractive. Whether you’re a startup watching every pound or an enterprise tired of escalating licence costs, Proxmox gives you enterprise features without enterprise prices. The money saved on licensing can go towards better hardware or additional training.

Development and test environments thrive on Proxmox’s flexibility. Developers can spin up full VMs for testing, lightweight containers for development, and quickly clone environments for experimentation. The web API enables integration with CI/CD pipelines and automation tools.

Service providers and MSPs appreciate Proxmox’s licensing model for multi-tenant environments. Without per-VM licensing, you can offer competitive hosting services whilst maintaining healthy margins. Built-in features like bandwidth limiting and backup scheduling help manage customer resources.

Container-forward organisations benefit from Proxmox’s dual VM/container nature. You can run legacy applications in VMs whilst modernising with containers, all on the same platform. LXC containers provide better isolation than Docker whilst maintaining near-native performance.

Educational institutions choose Proxmox for teaching virtualisation concepts without licensing concerns. Students can experiment freely, break things, and rebuild without worrying about compliance or costs.

So which one to go for?

Think about your team’s expertise first. Windows administrators will find Hyper-V familiar and manageable through PowerShell. Linux-savvy teams will appreciate Proxmox’s transparent foundation. Retraining costs can dwarf licensing savings if you choose against your team’s strengths.

Evaluate your workload mix, too. Windows-heavy environments naturally favour Hyper-V, whilst mixed or Linux-predominant workloads often run better on Proxmox. Container requirements particularly favour Proxmox’s native LXC support.

And then there’s your cloud strategy. If Azure is your destination, Hyper-V makes for a clearer path. For multi-cloud or on-prem, Proxmox’s independence gives more flexibility.

So Hyper-V offers the comfort of commercial software with Microsoft’s backing, while Proxmox sets you free from licensing constraints with surprising capability.
