Dedicated Server Operating Systems

Choose the Right OS or Hypervisor for Your Dedicated Server

Because there's no forced virtualization layer, a Qpeck dedicated server can run a standard operating system directly, or a hypervisor of your choosing installed straight onto the hardware. Pick the platform that matches how you actually plan to use the server.

Dedicated server hardware, no forced hypervisor

Install Linux or Windows directly

Or install your own hypervisor instead

Run multiple VMs on top of one server

The hardware doesn't dictate the platform — you decide whether the server runs one workload directly or many through virtualization.

Two ways to run your server

First decision

Do you need an OS or a hypervisor?

Before choosing a specific distribution or platform, decide whether your server will run one workload directly, or many through virtualization.

Install an operating system directly

Best if the server runs a single application, website, or database and you want every hardware resource going straight to it, with the simplest possible setup.

Install a hypervisor

Best if you want to run several isolated virtual machines on the same physical server — consolidating workloads, running test/dev environments, or standing up your own virtualization platform.

If you're installing an OS directly

Linux vs. Windows

Both run natively on the dedicated server hardware with full resource access — no virtualization overhead either way.

Feature	Linux	Windows
Best for	Web apps, open-source stacks	.NET apps, Microsoft-based software
Cost	Lower — no OS license fee	Higher — includes Windows Server license
Remote access	SSH	Remote Desktop (RDP)
Development stack	PHP, Node.js, Python, Ruby, Java	.NET, ASP.NET, C#
Database support	MySQL, PostgreSQL, MongoDB	Microsoft SQL Server, MySQL, PostgreSQL
Control panels	cPanel, Webmin, Plesk	Plesk, Windows Admin Center

If you're installing a hypervisor

VMware vs. Proxmox vs. Hyper-V

The right hypervisor usually comes down to licensing model and what your team already knows.

Category	VMware ESXi	Proxmox VE	Hyper-V
License	Commercial, per-CPU	Free, optional paid support	Included with Windows Server
Best for	Enterprises standardized on VMware	Budget-conscious, self-managed setups	Windows-centric environments
Management interface	vCenter / vSphere Client	Web-based Proxmox console	Hyper-V Manager / Windows Admin Center
Open source	No	Yes	No
Guest OS support	Broad, industry-standard	Broad (KVM VMs + LXC containers)	Strong Windows, solid Linux support

Decision guide

Which platform should you choose?

The fastest way to decide is to look at what's already in your stack, or how many workloads the server needs to run.

Linux is ideal for

Web hosting Kubernetes Docker MySQL PostgreSQL AI / ML frameworks Big data

Windows is ideal for

.NET applications Microsoft SQL Server Active Directory Remote Desktop Services Windows business software

Hypervisors are ideal for

Server consolidation Test / dev labs Disaster recovery Multiple isolated workloads

Pick a distribution

Linux distributions for dedicated server

All five distributions install directly on your dedicated hardware — here's a quick orientation before you choose.

Ubuntu

The most widely used Linux distribution, known for broad software support and frequent updates.

Best for: general hosting, Docker, developer environments

Debian

A stability-first distribution favored for long-term, low-maintenance deployments.

Best for: production servers, long-term stability

AlmaLinux

A free, RHEL-compatible distribution built as a long-term CentOS replacement.

Best for: enterprise workloads, cPanel hosting

Rocky Linux

Another RHEL-compatible distribution, built by the community for enterprise reliability.

Best for: enterprise apps, regulated environments

CentOS

A long-standing enterprise Linux option, now continued as the CentOS Stream branch.

Best for: teams already standardized on CentOS tooling

Pick an edition

Windows Server editions

Choose the Windows Server version that matches your application requirements and support timeline.

Windows Server 2025 VPS

Recommended workloads: latest .NET applications, modern Active Directory, hybrid cloud integrations.

Key features: current security baseline, newest IIS version, longest support window

Windows Server 2022 VPS

Recommended workloads: business applications, standard IIS/.NET hosting, Remote Desktop Services.

Key features: secured-core capabilities, mature ecosystem, broad software compatibility

Windows Server 2019 VPS

Recommended workloads: legacy application compatibility, established enterprise software.

Key features: familiar management tools, long deployment track record

Pick a hypervisor

Hypervisor options

Beyond the three most common choices, two open-source options round out what you can install on dedicated server.

VMware ESXi

Enterprise-grade virtualization for teams already standardized on VMware.

Proxmox VE

A free, open-source alternative combining KVM and container virtualization.

Hyper-V

Microsoft's hypervisor, integrated tightly with Windows Server environments.

KVM

Install KVM directly to run your own fleet of virtual machines on the hardware.

XCP-ng

An open-source Xen-based platform for teams wanting a Citrix Hypervisor alternative.

Freely Asked Questions

Which operating systems are supported on dedicated servers?

Dedicated servers support a wide range of operating systems, including Linux distributions such as Ubuntu, Debian, AlmaLinux, Rocky Linux, and CentOS Stream, as well as Microsoft Windows Server editions. Many dedicated servers also support virtualization platforms like VMware ESXi, Proxmox VE, Hyper-V, and KVM for hosting multiple virtual machines.

Should I choose Linux or Windows Server for my dedicated server?

The right operating system depends on your applications and workloads. Linux is commonly used for web hosting, WordPress, Docker, Kubernetes, PHP, Python, Node.js, and open-source databases. Windows Server is recommended for ASP.NET applications, Microsoft SQL Server, IIS, Active Directory, Remote Desktop Services, and other Microsoft technologies.

What is the difference between an operating system and a hypervisor?

An operating system runs applications directly on the dedicated server, while a hypervisor creates and manages multiple virtual machines on the same physical hardware. If you plan to host a single workload, installing Linux or Windows Server is usually the best option. If you need to run multiple isolated virtual servers, a hypervisor such as VMware ESXi, Proxmox VE, Hyper-V, or KVM is a better choice.

Which Linux distribution is best for a dedicated server?

The best Linux distribution depends on your environment. Ubuntu is widely used for cloud applications and development, Debian is known for stability, AlmaLinux and Rocky Linux are enterprise-ready distributions with long-term support, while CentOS Stream is suitable for testing and development environments.

Which hypervisor should I choose: VMware ESXi, Proxmox VE, Hyper-V, or KVM?

VMware ESXi is a popular enterprise virtualization platform with advanced management features. Proxmox VE combines KVM virtualization and Linux containers in an open-source solution. Hyper-V integrates with Windows Server environments, while KVM provides a flexible and efficient virtualization platform for Linux-based infrastructures. The best choice depends on your operating system, licensing preferences, and virtualization requirements.

Can I reinstall or change the operating system after deployment?

Yes. Dedicated servers can typically be reinstalled with another supported operating system or hypervisor whenever your infrastructure requirements change. Before reinstalling, ensure that important data is backed up because the process replaces the existing operating system and stored data.

Can I install my own operating system or virtualization platform?

Many dedicated server providers allow custom operating system installations using ISO images or remote management tools such as IPMI, iDRAC, or iLO. Availability depends on the server platform and deployment options offered by the provider.

How do I choose the right operating system or hypervisor for my dedicated server?

Choose the platform based on your workloads and management requirements. Linux is ideal for open-source applications, containers, and web hosting. Windows Server is recommended for Microsoft business applications and enterprise services. If your goal is to run multiple virtual machines or build private cloud infrastructure, virtualization platforms such as VMware ESXi, Proxmox VE, Hyper-V, or KVM provide the flexibility and resource management needed for those environments.
