Open source alternative to HashiCorp Terraform Cloud and Red Hat Ansible Automation Platform
Last verified
Manage local QEMU/KVM virtual machines on Linux from the terminal, with a TUI that skips libvirt entirely. GPL-3.0 licensed, written in Rust.
kudu supports x86_64, aarch64, and riscv64 QEMU targets, so developers building software for multiple architectures can spin up and manage test VMs for each target from one TUI on their local Linux machine, without a cloud provider.
Your cross-architecture testing runs on CI runners or cloud VMs managed by Terraform or Ansible. kudu manages VMs on the local host only and is not a remote infrastructure provisioning tool.
kudu works over SSH with no display server required. Homelab users running Linux on bare metal can create and manage QEMU/KVM VMs from a terminal session without installing a GUI stack, libvirt, or a web-based management interface.
You need a web UI for VM management or want to manage VMs across multiple hosts from one interface. kudu operates on the local machine only.
kudu is in the official Arch Linux package repository, so Arch users can install it with one pacman command and immediately start managing QEMU/KVM VMs without compiling from source or configuring a libvirt daemon.
You are on Debian, Ubuntu, Fedora, or another non-Arch distribution and prefer not to build from source. On those distros, you need Cargo and the Rust toolchain to compile kudu.
Running virtual machines on Linux typically requires either a GUI like virt-manager or GNOME Boxes, which depend on a graphical desktop session, or raw QEMU command invocations, which are verbose and difficult to manage across multiple VMs. Both paths have real friction: GUI tools do not work on headless servers or over SSH, and hand-typed QEMU commands require memorizing long argument lists and tracking VM state manually.
The libvirt daemon that backs most GUI VM managers adds another layer of complexity: a running service, its own configuration layer, and additional dependencies. For developers and homelab users who want direct QEMU/KVM access on a Linux host without that overhead, the existing tooling leaves a gap.
kudu talks directly to QEMU binaries without a libvirt daemon. This removes the libvirt service layer from the dependency stack, letting you manage VMs on hosts where libvirt is not installed and avoiding the configuration overhead of the libvirt abstraction.
Supports three QEMU system targets: qemu-system-x86 for x86_64, qemu-system-aarch64 for ARM64, and qemu-system-riscv for RISC-V. Each architecture uses the appropriate UEFI firmware package: ovmf on x86_64, edk2-aarch64 on ARM64, and edk2-riscv64 on RISC-V.
Uses xorriso to prepare cloud-init ISOs for automated first-boot configuration of cloud images. This lets you provision VMs with pre-set users, SSH keys, and packages without manual post-install steps inside the guest.
Uses passt for VM networking, which provides userspace network translation for QEMU VMs. passt is a required dependency and handles the network interface between host and guest without requiring kernel bridge interfaces or elevated networking privileges.
Runs entirely in the terminal as a TUI, making it usable over SSH and on headless Linux servers where GUI tools require a display server. Start it with a single command: kudu. KVM acceleration is used when the kvm kernel module is loaded; kudu still runs without it.
kudu and Terraform both touch virtual machine lifecycle, but from different positions. Terraform provisions infrastructure resources on cloud providers (AWS, GCP, Azure) or on-premise systems via provider APIs, tracking state across many resources. kudu manages VMs directly on a local Linux host using QEMU/KVM, with no cloud provider or API layer.
| Feature | kudu | HashiCorp Terraform |
|---|---|---|
| License | GPL-3.0 | BSL 1.1 (since 1.6.0) |
| Primary use | Local VM management | Cloud and on-premise infra provisioning |
| VM backend | QEMU/KVM direct | Provider-dependent (AWS, vSphere, etc.) |
| Interface | Terminal UI | HCL configuration files |
| Cost | Free (GPL-3.0) | Free CLI; paid Terraform Cloud tiers |
Terraform is the better choice when you need to provision and manage infrastructure across cloud providers at scale, with plan/apply workflows, remote state, and team collaboration. kudu is the better choice when you need to run and manage VMs locally on a single Linux machine for development, testing, or homelab use, without involving a cloud provider or writing HCL.
Red Hat Ansible Automation Platform is a paid, subscription-based product for enterprise configuration management and automation across server fleets. kudu is a single-host local VM manager with a terminal UI.
| Feature | kudu | Red Hat Ansible Automation Platform |
|---|---|---|
| License | GPL-3.0 | Proprietary (subscription) |
| Scope | Single Linux host | Multi-host server fleet |
| Primary function | VM creation and management | Configuration management and automation |
| Cost | Free | Paid subscription |
| Interface | Terminal UI | Web UI and CLI |
Ansible Automation Platform is the right choice for organizations that need to automate configuration across a server fleet with enterprise support, role-based access, and Red Hat ecosystem integration. kudu addresses a distinct need: running and managing local QEMU/KVM VMs on one Linux machine from the terminal, with no subscription, no remote service, and no fleet coordination required.
Install kudu via pacman on Arch Linux, or build from source using Cargo.
```bash
pacman -S kudu
```
```bash
git clone https://github.com/pythops/kudu
cd kudu
cargo build --release
```No. kudu talks directly to QEMU binaries without libvirt. This is the primary difference from GUI tools like virt-manager and GNOME Boxes, which both depend on libvirt. You do not need to install or run the libvirtd service to use kudu.
kudu supports x86_64, aarch64 (ARM64), and riscv64 via the corresponding QEMU system emulators. You need the relevant qemu-system-x86, qemu-system-aarch64, or qemu-system-riscv binary on the host. UEFI firmware packages (edk2-aarch64, edk2-riscv64) are required for aarch64 and riscv64 guests; on x86_64 they are optional.
First, make sure the kvm kernel module is loaded if your processor is Intel or AMD. If you run kudu as a regular user, confirm your user belongs to the kvm group. If not, add your user to the group or run kudu with sudo. The README notes that kudu still runs without KVM available, just without hardware acceleration.
No. kudu requires a Linux-based OS. It depends on KVM, which is a Linux kernel feature, and on Linux-packaged QEMU binaries. The project README lists a Linux-based OS as a hard prerequisite, and there is no macOS or Windows build available.
