Desktop virtualization software: local VMs, VDI, and DaaS

Desktop virtualization software lets you run a desktop operating system in a virtual environment, either on your own computer or on infrastructure you access remotely. The right software depends on where applications need to run, who manages them, and how much control each user needs.

A developer testing Linux on a laptop has different requirements from an IT team delivering Windows apps to hundreds of employees. This guide separates local virtual machines, virtual desktop infrastructure (VDI), shared sessions, and desktop as a service (DaaS), then explains how to compare software, compatibility, performance, security, and costs.

How desktop virtualization works

A hypervisor provides virtual hardware on which a guest operating system runs. It allocates CPU time, memory, storage, and other resources from a physical machine. Multiple virtual machines can run on one host, but they still compete for its available capacity.

With local virtualization, you interact with the guest desktop through software on your computer. The host operating system remains available alongside the guest. A Windows laptop, for example, can run a supported Linux guest for software development without replacing its main installation.

With remote desktops, applications execute elsewhere and a display protocol carries screen updates, keyboard input, and other supported interactions between the session and the endpoint. Enterprise deployments also need identity controls, connection brokering, images, profiles, monitoring, and support. A hypervisor alone does not provide that whole service.

Remote access and virtualization are not synonyms. Remote desktop software can connect to a physical PC, while a local VM may never accept a remote connection. Keep those distinctions clear when comparing products.

Choose the desktop delivery model first

Model	Where work runs	Typical fit and main constraint
Local virtual machine	On the user's computer, within a guest OS	Development, learning, and testing; limited by local hardware and guest compatibility
VDI	In individual desktop VMs on centrally managed infrastructure	Separate desktop environments for users; requires desktop delivery and operational management
Shared session desktop	Several user sessions on one supported operating system instance	Standardized applications; compatibility and resource contention need testing
DaaS	On a service provider's supported desktop infrastructure	Outsourcing selected infrastructure tasks; responsibilities vary by service

DaaS describes how a service is delivered, so it can overlap with VDI or shared-session architectures. It does not mean every application, policy, backup, and support task belongs to the provider.

Shared sessions can reduce the number of operating system instances an organization manages, but not every application supports multiple simultaneous users. Microsoft's Remote Desktop Services overview explains the roles used to deliver Windows Server sessions and applications. Confirm the relevant access rights and licensing for the chosen design.

Local desktop virtualization software

Start with the host operating system and processor architecture. Then check the exact guest OS, application dependencies, device support, and automation features you need. Product familiarity is useful, but it cannot overcome an unsupported guest configuration.

VMware Workstation and Fusion

VMware Workstation runs on supported Windows and Linux hosts; VMware Fusion runs on supported Macs. Both are local tools for creating and operating virtual machines. Broadcom's current download and licensing guidance states that eligible Workstation Pro and Fusion Pro releases are free for commercial, educational, and personal use. Guest operating systems and applications can still require their own licenses.

On Apple silicon, Fusion runs supported Arm guest operating systems rather than virtualizing an x86 operating system. Running an x86 application through translation inside Windows on Arm is a separate capability, with its own limits. Check Broadcom's guest architecture guidance before moving an existing VM from an Intel machine.

Oracle VirtualBox

Oracle VirtualBox is a local virtualization option with packages for several host platforms and support for multiple guest operating systems. The Oracle documentation distinguishes the GPL-licensed base package from the optional Extension Pack, which has separate licensing terms. Check those terms before deploying extension features in a business.

For a test lab, evaluate virtual networking, snapshots, device integration, and command line management against the actual host and guest combination. An open-source base package does not make every extension or guest application free of licensing requirements.

Parallels Desktop

Parallels Desktop targets running additional operating systems on a Mac, including Windows apps alongside macOS applications. On Apple silicon, supported Arm guests are the main virtualization path. Parallels also documents an x86 emulation preview, which should not be treated as equivalent to its supported Arm workflow.

Use the current system requirements to check macOS, hardware, guest versions, and feature limits. Test the specific Windows application and its drivers before assuming that running Windows means every Windows app will work.

Microsoft Hyper-V

Hyper-V is a Windows virtualization option for creating and managing VMs. Microsoft's installation documentation covers supported Windows editions and hardware requirements, including processor virtualization support. The Hyper-V role is not available in Windows Home.

For a developer already using a supported Windows edition, it is worth evaluating before buying another local hypervisor. Hyper-V by itself is not a complete managed desktop service: delivering remote sessions to a workforce still requires the appropriate access, management, and licensing components.

Software for VDI and cloud desktops

For organizational deployments, compare the management boundary as carefully as the desktop interface. Ask which party operates the connection service, session hosts, images, profiles, applications, identity integration, and recovery process.

Omnissa Horizon 8

The current product name is Omnissa Horizon, previously VMware Horizon. Horizon 8 supports virtual desktops and published applications across supported deployment environments. Its architecture includes connection brokering, desktop agents, clients, and components for remote access.

Consider it when your team needs an enterprise desktop-delivery platform and can operate the supporting infrastructure. Confirm the deployment architecture and support matrix rather than assuming every hypervisor, cloud, and guest combination is interchangeable.

Citrix DaaS

Citrix DaaS provides cloud-based management for application and desktop delivery, with supported workloads in customer-managed locations or cloud environments. The responsibility split depends on the service and deployment option. A cloud control plane does not automatically make the session machines, applications, or user policies provider-managed.

Azure Virtual Desktop and Windows 365

Azure Virtual Desktop provides desktop and application delivery with personal or pooled session hosts and supported single-session or multi-session operating systems. Microsoft manages service components, while your team still has work to do around hosts, images, applications, and access. Our Azure remote desktop guide covers this deployment choice in more detail.

Windows 365 provides Cloud PCs as a service. It can suit organizations that want a more packaged desktop offering, but IT still needs to manage applications, identities, and policies. Compare the actual edition and configuration rather than assuming all Microsoft cloud desktops have the same operating model.

Amazon WorkSpaces

Amazon WorkSpaces distinguishes Personal desktops, assigned persistently to users, from nonpersistent Pools. Supported operating systems, bundles, protocols, and billing arrangements depend on the selected option. Verify those details together, especially when comparing a named user's everyday workstation with a pool used by changing groups.

Persistent desktops, images, and user profiles

A persistent desktop retains its assigned environment across sessions. A nonpersistent desktop returns to a managed baseline according to the platform's lifecycle and configuration. That reset may happen at logoff, restart, or another defined event; do not assume identical behavior across products.

User files and settings can be stored separately from the desktop image. This allows a disposable desktop to reconnect a user's profile, but creates dependencies on profile storage, permissions, application behavior, and recovery. Citrix's delivery methods documentation describes several combinations of machines, sessions, and persistence.

Choose based on the work. A controlled training environment may benefit from a resettable image. A specialist workstation may need retained tools and configuration. In both cases, assign responsibility for updating images and protecting user data.

Check application compatibility and performance

Build the shortlist around applications, not a generic user count. Record the operating system, CPU architecture, memory demand, storage behavior, peripherals, and required integrations. Linux guests such as Ubuntu or Red Hat Enterprise Linux still need a supported release and architecture; a vendor listing Linux support is not a promise about every distribution.

For remote users, test the real connection path, display layout, video calls, file access, and USB or printer requirements. Microsoft's RDP bandwidth guidance shows why requirements vary with content and session activity. A single bandwidth or latency threshold cannot establish whether every application will be usable.

GPU acceleration and GPU passthrough

A virtual graphics adapter, shared vGPU, and a whole GPU assigned through passthrough are different arrangements. Supporting desktop graphics or a particular DirectX feature does not establish support for CUDA, every professional application, or every GPU model.

For NVIDIA vGPU deployments, check the complete support combination: hardware, hypervisor, guest OS, software release, profile, and license. Our NVIDIA GRID and vGPU guide explains the terminology and deployment choices. Measure representative workloads rather than assuming shared GPUs always lose a fixed percentage of performance.

Data security and recovery need explicit configuration

Centralizing desktops can make access policies and application updates easier to coordinate. It also concentrates dependencies: an identity, profile-storage, or connection-service outage can affect many users at once.

Use multifactor authentication, limited administrative access, supported remote-access paths, and patching for hosts, guests, and endpoints. Microsoft's Azure Virtual Desktop security recommendations describe the shared responsibilities involved. Shared sessions need particular care because users operate within the same OS environment.

Data can leave a remote desktop through allowed drive, clipboard, printer, or other redirection. Screenshots and application-level transfers also matter. Review the controls against the work people need to do; do not promise that virtualization makes data extraction impossible.

Snapshots can help reverse some changes, but they do not replace a backup and recovery plan. Test restoration of user files, profiles, and required configuration. Keep backup protection separate from the credentials and infrastructure that an incident could compromise.

Compare the full cost and management workload

Include desktop or hypervisor subscriptions, operating system and application rights, compute, storage, backups, networking, support, and staff time. Check how idle capacity, retained disks, user assignments, and minimum commitments affect the bill. A free local hypervisor does not remove hardware costs, and usage-based infrastructure does not remove application licensing.

For infrastructure you manage yourself, Compute with Hivenet provides CPU and GPU compute resources. Evaluate those resources against the workload, but confirm supported OS images, remote desktop software, licenses, networking, and persistence before designing a desktop service around them. General compute capacity is only one component of that design.

Do not size an entire deployment from one quiet test session. Simultaneous logins, application launches, updates, and video meetings can expose limits that average utilization conceals.

Run a pilot before choosing the software

1. Define representative user groups. Separate development, office applications, shared task work, and graphics-heavy workloads.
2. Verify the supported stack. Record host and guest versions, CPU architecture, application rights, GPU requirements, and required devices.
3. Assign operational ownership. Name who handles identity, images, profiles, patches, monitoring, backups, and support.
4. Test ordinary and peak work. Measure task completion, login time, responsiveness, storage latency, and session quality with real applications.
5. Test failures and recovery. Include a disconnected client, unavailable desktop, damaged profile, and file restoration.
6. Compare the complete cost. Use observed demand and operating effort, then expand gradually with documented acceptance criteria.

Desktop virtualization software FAQs

What is the best desktop virtualization software?

For local VMs, shortlist tools that support your computer, guest OS, and applications. For managed remote desktops, compare delivery architecture, operational responsibilities, and user requirements. A product that fits a developer's laptop is not necessarily suitable for an organization's desktop fleet.

Can a virtual desktop work offline?

A local VM can run without a network when its applications and required files allow it. A remotely hosted desktop generally needs a working connection to its service. Application licensing, authentication, and data access can introduce additional network dependencies in either model.

Is a nonpersistent desktop the same as deleting user data?

No. The desktop's local state may reset while files and profiles persist in separate storage. Confirm where each type of data lives, when the reset happens, and how it is backed up.

Does desktop virtualization guarantee lower costs?

No. Savings depend on utilization, licensing, infrastructure, support, and management effort. Use a workload-based pilot and a complete cost model rather than a universal savings percentage.
