QEMU can emulate almost anything, but driving it means hand-writing long command lines. Aleph Void QEMU Manager is a desktop app that creates, configures and runs QEMU virtual machines for you, from a Windows 11 guest with TPM 2.0 to a RISC-V or IBM Z board, with the same app on every desktop OS.
Nothing hidden: view the exact QEMU command line for any VM and add your own arguments. Each VM is a portable folder you can copy, back up or move.
Build a VM from a hardware list, start it, and watch it boot in an embedded console. QEMU Manager writes the command line, supervises the helpers and keeps every VM in its own folder.
x86, ARM, RISC-V, POWER, MIPS, LoongArch, IBM Z, SPARC, m68k, Alpha and PA-RISC. Pick the machine type and CPU model from the lists your installed QEMU reports, with descriptions, or type your own.
Add and remove devices the way Proxmox does: CPUs and memory, BIOS or UEFI, virtio, NVMe, SATA, IDE and USB disks, ISOs, boot order, sound cards, serial ports and host USB devices.
Give a VM a virtual TPM emulated by swtpm, for Windows 11 or BitLocker. TPM keys and UEFI variables live in the VM's folder and carry over to clones.
Snapshot a running VM and its memory is saved too, so restoring resumes exactly where it was, even after a shutdown. Snapshots cover every qcow2 disk plus the UEFI variable store.
Full clones copy every disk. Linked clones are instant copy-on-write overlays on the original disks, so ten test machines cost almost no space.
Import appliances from VMware, VirtualBox and other tools. Manifests are checked; CPUs, memory, disk controllers, NICs, MACs and UEFI are mapped; disks convert to qcow2. Exports round-trip exactly.
Uses KVM on Linux, Hypervisor.framework on macOS and WHPX on Windows automatically when the guest matches the host CPU, and falls back to TCG emulation when it doesn't.
An in-app display built on noVNC, with a fresh random VNC password for every boot. Prefer a native QEMU window or headless mode? Both are one setting away.
Pass a GPU or other PCIe device to a VM with VFIO on Linux. The app shows each device's driver and IOMMU group and tells you what to fix before it can be passed through.
Share host folders with the guest over virtio-fs (Linux hosts) or 9p (Linux and macOS hosts). The app shows the mount command to run in the guest.
User-mode NAT with port forwarding everywhere, bridged and TAP networking on Linux, TAP-Windows adapters on Windows and vmnet on macOS. Only modes your host supports are offered.
See the exact QEMU command line for any VM and add your own extra arguments. Start, pause, resume, reset, shut down or force stop over QMP, with live status and the QEMU log.
QEMU Manager doesn't replace QEMU. It drives the QEMU you have installed, keeps each VM in a self-contained folder, and talks to the running machine over QMP.
The app finds QEMU on your PATH and in standard install locations, reads which machines and CPUs it supports, and can help you install or update it.
Every VM is a folder holding vm.json, its disks, UEFI variables and TPM state. Copy it to another machine, back it up, or keep it in a synced drive.
QEMU, swtpm and virtiofsd are spawned directly, never through a shell. VNC and QMP listen only on loopback or a private socket.
Use Homebrew, apt, dnf, pacman or winget. QEMU Manager detects it automatically.
Pick an architecture and an installer ISO, or import an OVA appliance.
Start the VM and install the guest OS in the embedded console.
Save a known-good state, then spin up linked clones to experiment.
Every guest ISA your QEMU build includes, with devices attached on each machine's own bus: PCI, IBM Z channel I/O, or virtio-mmio.
QEMU is not bundled. Install it with your platform's package manager; QEMU Manager searches PATH and standard locations, or you can set the folder in Settings.
| Platform | Install command |
|---|---|
| macOS | brew install qemu swtpm |
| Debian / Ubuntu | sudo apt install qemu-system qemu-utils ovmf virtiofsd swtpm |
| Fedora | sudo dnf install qemu-kvm qemu-img edk2-ovmf virtiofsd swtpm |
| Arch | sudo pacman -S qemu-full edk2-ovmf virtiofsd swtpm |
| Windows | winget install SoftwareFreedomConservancy.QEMU or the installer from qemu.org |
On Linux, add yourself to the kvm group for hardware acceleration. Bridged networking, PCI passthrough and vmnet need some host setup; see the host setup notes.
One license covers every platform. Signed and notarized on macOS, signed on Windows, with SHA-256 checksums for every package.

No. QEMU is a separate program (GPL-2.0) that QEMU Manager runs as an external process; it is not linked or distributed with the app. Install it with your platform's package manager (see Requirements), and the app's QEMU page can help you install or update it.
macOS (Apple Silicon and Intel), Windows (x64 and ARM64) and Linux (x64 and ARM64). Some features depend on the host: PCI passthrough and virtio-fs are Linux-only, 9p shared folders need a Linux or macOS host, and TPM 2.0 is unavailable on Windows hosts because QEMU's Windows build has no TPM emulator backend.
Yes. Windows 11 needs UEFI firmware and a TPM 2.0. Install swtpm on a Linux or macOS host, choose UEFI and add a TPM in the VM's hardware list. On an x86-64 host with KVM, Hypervisor.framework or WHPX it runs with hardware acceleration.
When the guest architecture matches your CPU, QEMU Manager picks the host's accelerator automatically: KVM on Linux, Hypervisor.framework on macOS, WHPX on Windows. Other architectures run under TCG emulation, which is slower but works everywhere.
Yes, export them as OVA or OVF and import them. QEMU Manager checks the manifest, maps CPUs, memory, disk controllers, NICs, MAC addresses and UEFI, and converts the disks to qcow2. It can also export OVAs with stream-optimized VMDK disks and a SHA-256 manifest.
Each VM is a folder (a "bundle") holding vm.json, its disks, UEFI variables and TPM state. Nothing is kept in a hidden database, so you can back up, copy or move a VM like any other folder.
Buy once from the Aleph Void Store and you get a license key that works on macOS, Windows and Linux, on up to 10 machines. The key is checked with Gumroad the first time, then periodically; the app keeps working offline for weeks between checks, and a network hiccup never locks a running session.
No analytics or telemetry. The app only goes online to verify your license key with Gumroad and, when you ask it to, to check for QEMU updates. See the Privacy Policy.
Open an issue on our GitHub issue tracker, or see the Support page. Include your host OS, QEMU version, the guest architecture and the steps to reproduce.
