GpuVM

English | Español

What it does

• Your GPU inside the VM. Hyper-V GPU partitioning (GPU-P) shares the host GPU with the VM, which runs the same driver as the host. No passthrough, no second GPU.
• Open it in one click. "Start and open" starts the VM, waits for Windows, fixes the session and the display, pairs Moonlight and opens the stream, drawn and encoded by the GPU (Sunshine + NVENC), with sound.
• Fixes itself. It copies the GPU driver again when the host driver changes, puts the Windows session back on the GPU display and matches the display resolution to Moonlight.
• Create machines without the installer. Pick an official Windows ISO and a profile: the image is applied straight to a disk and set up unattended.
• Stats and options. Live CPU, memory and GPU usage; processors, memory, GPU share and stream quality for each VM.
• Library. Your own profiles (processors, memory, GPU, disk, ISO, apps, how Moonlight opens), the disks kept from deleted VMs to create them again, and the ISOs you used.
• Templates and shared disks. Save a VM as a template and create new ones on top of it in seconds; keep your game library on a shared disk that moves between VMs, imported from your PC's Steam library.
• Clean Windows. Pick a level (privacy, no extra apps, minimal) to cut telemetry, ads, suggestions, Copilot and preinstalled apps, without touching Defender, Windows Update or the firewall.
• Apps in one step. 16 apps (game launchers, browsers, media, Discord, 7-Zip, WinRAR, Proton VPN) with search and categories, installed inside the VM only if signed by their publisher or matching a pinned hash.
• Games in exclusive fullscreen. A per-VM capture option shows them instead of a black screen; paste text from the PC into the VM with one button.
• Keeps the host apart. Moonlight runs without administrator rights, and the clipboard only goes from the PC to the VM, never back.
• Labs. Every performance idea is measured (baseline vs candidate) before it becomes a default.

Requirements

• Windows 10/11 Pro, Enterprise, Education or Pro for Workstations, with Hyper-V enabled.
• A GPU that supports partitioning (tested with an NVIDIA GeForce RTX 4060).
• PowerShell 7 (MSI or Microsoft Store).
• An official Windows 10 or 11 ISO.

Enable Hyper-V once, as administrator, then restart:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Install

Download GpuVM_x.y.z_x64-setup.exe from Releases and run it. GpuVM installs for every user in Program Files and asks for administrator rights when it opens, because Hyper-V requires them. Data that changes (labs, downloads) lives in %ProgramData%\GpuVM.

Quick start

1. Open GpuVM and choose Crear máquina (Create machine): name, Windows ISO, profile and the Windows password.
2. Wait until it's ready; Windows finishes its setup on its own in a few minutes.
3. Press Abrir (Start and open). Moonlight opens with the VM.

The interface is in Spanish for now.

How it works

Piece	Role
app/	Desktop app (Tauri 2 + React). Talks to PowerShell through src/bridge.ps1.
src/GpuVM/	PowerShell 7 module: creation, profiles, driver sync, streaming, labs. Backends are swappable (Backends/).
guest/	Scripts that run inside the VM: first boot, optimizations, streaming, display resolution.
profiles/	JSON profiles with inheritance (balanced, max-performance).
streaming/components.json	Third-party components pinned by version and SHA-256.
labs/	Measurements behind each decision.

Development

npm --prefix app install
npm --prefix app run dev          # UI with sample data in the browser (?mock=empty, ?mock=noadmin)
npm --prefix app run tauri build  # installer in app/src-tauri/target/release/bundle/nsis/
Invoke-Pester ./tests             # module tests, no administrator needed
npm --prefix docs run dev         # documentation site
node scripts/site/changelog.mjs   # website (site/): what's new, from the changelogs
npm --prefix app run build:embed  # website: the app's live components (site/assets/embed.js)
python scripts/release.py 0.4.1   # release: changelog, versions, commit and tag (--dry-run, --next)

Changes go under Unreleased in CHANGELOG.md and Sin publicar in CHANGELOG.es.md until they are released.

The CLI covers the same features: ./gpuvm.ps1 check, new, connect, list, sync-driver, set, remove, lab-* (see the docs).

Third-party components

GpuVM downloads and installs these inside the VM, verified by SHA-256:

• Sunshine (GPL-3.0) — game stream host.
• Virtual Display Driver — virtual monitor drawn by the GPU.
• nefcon — driver installer.
• usbip-win2 (BSD-2-Clause) — USB/IP client with Microsoft-signed drivers; it plugs in GpuVM's own USB speaker inside the VM.

On the host it uses Moonlight (GPL-3.0), installed with winget.

The app catalog shows each app's own icon, taken from its official installer or website; the icons and names are trademarks of their owners and only identify their apps.
