Introducing vm‑curator: A Fast Rust TUI for Managing QEMU/KVM Virtual Machines
vm‑curator is a fast, open‑source Rust‑based TUI that lets developers and sysadmins create, launch, and manage QEMU/KVM virtual machines on Linux with full 3D‑acceleration support, all from a sleek terminal interface.
What Is vm‑curator? An Overview for Linux Virtualization Enthusiasts
vm‑curator is a community‑driven project written in Rust that provides a text‑based user interface (TUI) for building and managing desktop‑focused QEMU/KVM virtual machines. Unlike heavyweight hypervisor managers such as virt‑manager or libvirt, vm‑curator targets developers, system administrators, and hobbyists who need a lightweight, script‑driven workflow with instant access to GPU‑passthrough and para‑virtualized 3D acceleration.
The tool automatically scans a user‑defined VM library, parses existing launch.sh scripts, and presents a hierarchical view of Windows, Linux, macOS, BSD, and other OS families. Its built‑in wizard guides you through creating new VMs, selecting ISO images, configuring CPU, memory, and storage, and even setting up complex GPU passthrough scenarios—all without leaving the terminal.
For anyone looking to spin up high‑performance Linux VMs for development, testing, or gaming, vm‑curator offers a concise, no‑frills experience that stays true to the Unix philosophy.
Key Features & Benefits of the Rust TUI VM Manager
Below is a MECE‑structured list of the most compelling capabilities that set vm‑curator apart from other open‑source VM tools.
- Full‑stack GPU Passthrough: Supports single‑GPU, multi‑GPU, and USB controller passthrough with VFIO, enabling near‑native graphics performance for gaming or GPU‑intensive workloads.
- Automatic VM Discovery: Scans the configured library directory for
launch.shscripts, categorising VMs by OS family for instant navigation. - 5‑step Creation Wizard: Over 50 pre‑configured OS profiles (Windows 95‑11, Ubuntu, Debian, macOS, BSD, etc.) with optimal QEMU flags, UEFI detection, and disk sizing.
- Snapshot Management: Create, list, restore, and delete qcow2 snapshots directly from the TUI, with timestamps and size indicators.
- USB & PCI Passthrough UI: Enumerates devices via
libudev, lets you select GPUs, NICs, NVMe drives, and USB 3.0 controllers for inclusion in the VM launch script. - Vim‑style Navigation: Keyboard‑centric controls (j/k, arrows, PgUp/PgDn) for rapid browsing, plus mouse support for those who prefer it.
- Cross‑Distribution Packages: Pre‑built DEB, RPM, AppImage, and Arch AUR packages, plus
cargo install vm-curatorfor Rust users. - Contextual Help System: Inline tooltips explain each setting, reducing the learning curve for newcomers.
- Open‑Source & Extensible: MIT‑licensed, with a modular architecture that encourages community contributions (e.g., custom ASCII art, new OS profiles).
These features translate into tangible benefits: faster VM provisioning, reduced configuration errors, and the ability to harness GPU power without the overhead of full virtualization stacks.
Installation & Quick‑Start Guide
Prerequisites
Before installing vm‑curator, ensure your Linux host meets the following requirements:
- Rust 1.70+ (for building from source)
- QEMU system binaries (e.g.,
qemu-system-x86_64) libudev-devon Debian/Ubuntu orlibudevon Arch/Fedora- Hardware‑virtualisation enabled (VT‑x/AMD‑V) and IOMMU support for GPU passthrough
Building and Installing
git clone https://github.com/mroboff/vm-curator.git
cd vm-curator
cargo build --release
sudo cp target/release/vm-curator /usr/local/bin/Alternatively, install a pre‑built package:
- Debian/Ubuntu:
sudo apt install vm-curator - Fedora/RHEL:
sudo dnf install vm-curator - Arch Linux:
yay -S vm-curator - AppImage: download the AppImage
First Run & Basic Commands
Launch the TUI with a simple command:
vm-curatorKey shortcuts inside the interface:
- Enter – Launch the selected VM
- c – Open the creation wizard
- m – Manage snapshots, edit launch scripts, rename VMs
- s – Open settings (default library path, memory, CPU defaults)
- ? – Show contextual help
For CLI‑only workflows, vm‑curator also provides commands such as vm-curator list, vm-curator launch <vm-name>, and vm-curator snapshot <vm> create <name>.
How vm‑curator Stacks Up Against Traditional VM Managers
While tools like virt‑manager and libvirt offer extensive feature sets for server‑grade virtualization, vm‑curator focuses on a specific niche: desktop‑oriented, high‑performance VMs with minimal overhead.
Feature Comparison Table
| Aspect | vm‑curator | virt‑manager / libvirt |
|---|---|---|
| Interface | Terminal‑based TUI (no X server needed) | GUI + CLI |
| GPU Passthrough | Built‑in single & multi‑GPU support | Supported via XML, more complex |
| Installation Footprint | ~10 MB binary, optional packages | Hundreds of MB, daemon services |
| Learning Curve | Keyboard‑centric, wizard‑driven | Steeper, XML editing required |
| Extensibility | Open source, Rust plugins possible | Extensive API, but heavier |
Ideal Use‑Cases
- Game Development & Testing: Spin up a Windows VM with direct GPU access for testing DirectX/Vulkan titles.
- AI/ML Experimentation: Allocate a dedicated GPU to a Linux VM for TensorFlow or PyTorch workloads without affecting the host.
- Cross‑Platform CI: Quickly launch disposable VMs for building and testing software across Windows, Linux, and macOS.
- Educational Labs: Provide students with isolated environments that mimic real hardware, all managed from a single terminal.
A Glimpse of vm‑curator in Action
