Install: Run the .exe, accept the license, choose a folder, and finish. QuantaBox installs to C:\Program Files\Dyber\QuantaBox by default. See Installation.

Hardware acceleration: QuantaBox uses a hardware-accelerated backend. On Windows it will use Hyper-V / WHPX when available, otherwise it falls back to software emulation. See System Requirements.

Install: Open the .dmg and drag QuantaBox to Applications. See Installation.

Prerequisite: QEMU Engine #

QuantaBox uses QEMU as its execution engine. The Windows installer can bundle a compatible QEMU build for you. On Linux and macOS, install QEMU from your package manager if it is not already present:

# Debian / Ubuntu
sudo apt install qemu-system-x86 qemu-utils

# Fedora / RHEL family
sudo dnf install qemu-kvm qemu-img

# macOS (Homebrew)
brew install qemu

QuantaBox automatically detects QEMU in standard locations. You can confirm detection at any time with:

quantabox status

See Installation for details on configuring the QEMU engine.

System Requirements #

MinimumRecommended
CPU64-bit x86 with virtualization (Intel VT-x / AMD-V)4+ cores with VT-x/AMD-V or Apple Silicon
RAM4 GB16 GB+ (host + guests)
Disk10 GB free (app + one small VM)SSD with room for your VM disks
OSWindows 10, a current Linux, or macOS 13Windows 11, current Linux, macOS 14+
AccelerationOptional (software fallback works)Hyper-V/WHPX, KVM, or Hypervisor.framework enabled

Enabling Acceleration

  • Windows - Enable the Windows Hypervisor Platform feature (and/or Hyper-V) and ensure virtualization is on in firmware/BIOS.
  • Linux - Ensure /dev/kvm exists and your user can access it (the kvm group).
  • macOS - Hypervisor.framework is built in; no action required.

See Troubleshooting for help if acceleration is not available.

Verifying Your Download #

Each release ships a SHA256SUMS file. Verify your download before installing:

# Linux / macOS
sha256sum -c SHA256SUMS

# Windows (PowerShell)
Get-FileHash .\QuantaBox-1.0.0-Setup-x64.exe -Algorithm SHA256

Compare the printed hash against the value in SHA256SUMS. For maximum assurance, verify the detached signature (SHA256SUMS.sig) against the Dyber release signing key published at dyber.org.
