GNOME Boxes vs UTM

GNOME Boxes is a free Linux desktop app for creating and managing local virtual machines, then installing an operating system in them. Its automatic installation list includes CentOS Stream, Debian, Fedora, Microsoft Windows, OpenSUSE, Red Hat Enterprise Linux, and Ubuntu. Users can set memory and storage limits, save a VM state as a snapshot, and restore it later. Host integration includes shared clipboard, file drop, and shared folders; USB redirection makes devices plugged into the computer available inside a VM. Guest tools can improve input performance, screen resizing, clipboard sharing, and file transfer. Windows guests use spice-guest-tools, while Linux guests commonly use spice-vdagent. Boxes uses qemu-kvm, libvirt-glib, and spice-gtk to manage virtual machines. Three-dimensional acceleration is available for some supported systems. GNOME recommends processor virtualization extensions, at least 8 GB RAM, and 20 GB free disk space for efficient use. Boxes is for local VMs; GNOME points to Connections for remote machines and displays. The app is free and desktop-only.

UTM is a system emulator and virtual-machine host for macOS and iOS that can run Windows, Linux, and other operating systems. Its QEMU backend supports more than 30 processor types, including x86_64, ARM64, ARM32, MIPS, PPC, and RISC-V. On Apple Silicon, UTM uses Apple’s Hypervisor framework for ARM64 systems; Intel Macs can virtualize x86/x64, while Apple Silicon can emulate those architectures at lower performance. Apple Virtualization is also available for macOS and Linux on Apple Silicon. Virtual machines can run with a graphical display, terminal console, or headless, and support snapshots, nested virtualization, and multiple displays. The Mac app supports USB devices, bridged or shared networking, and external-drive storage; iOS supports shared directories, clipboard sharing, and port forwarding. macOS guests are limited to ARM-based Macs running macOS Monterey or later. Windows GPU acceleration is unavailable, and Linux hardware OpenGL acceleration is experimental. The GitHub version is free; the Mac App Store version costs 9.99 USD once and adds automatic updates.
