StratoVirt vs UTM

StratoVirt has no write-up on Specifiction yet; its figures are above.

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.
