GNOME Boxes vs Multipass

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.

Multipass runs cloud-style virtual machines on Linux, macOS, and Windows workstations. It is intended for prototyping cloud deployments locally and creating customized Linux development environments. Instances can use cloud-init metadata, including custom definitions for configured servers, and local workflows can model deployments for AWS, Azure, Google, IBM, and Oracle. Multipass fetches Ubuntu images from Canonical and offers a growing catalogue of images with pre-installed applications. Users can share host files and folders with instances; the primary instance integrates with the native filesystem and has dedicated hot-key access. Both command-line and graphical interfaces are available, and the documentation covers Windows Terminal integration and running Docker containers in an instance. Host hypervisors are Host Compute System on Windows, Apple Virtualization on macOS, and QEMU on Linux. The product is free; the listed plan costs nothing, with host requirements varying by operating system. Anyone with access to the Multipass daemon socket can fully control the software, including mounting host filesystems and changing instance security features. Canonical advises limiting daemon access to trusted users. Its access controls begin with group membership and can later use a user TLS certificate.
