GXemul aims at emulating complete machines with enough hardware emulated to run real unmodified operating systems. The emulation of these machine types is good enough to run a least one guest operating system:

ARM-based machines: * CATS (NetBSD/cats, OpenBSD/cats, Debian GNU/Linux) * IQ80321 (NetBSD/evbarm) * NetWinder (NetBSD/netwinder) * Raspberry Pi (NetBSD/raspberrypi, FreeBSD, HelenOS/rpi) MIPS-based machines: * Acer Pica-61 (NetBSD/arc, Windows NT) * Algorithmics P5064 (NetBSD/algor) * Cobalt (NetBSD/cobalt) * DECstation 5000/200 (NetBSD/pmax, OpenBSD/pmax, Ultrix, Linux/DECstation, Sprite), DECstation 5000/1xx (raw PROM) * Malta (NetBSD/evbmips, Linux/Malta) * NEC MobilePro 770, 780, 800, 880 (NetBSD/hpcmips) * PlayStation 2 (NetBSD/playstation2) * SGI O2 (NetBSD/sgimips, OpenBSD/sgi, Linux, IRIX, raw PROM) * VoCore (FreeBSD/vocore, Linux/vocore) Motorola 88K-based machines: * Luna 88K (OpenBSD/luna88k) * Motorola MVME187 (OpenBSD/mvme88k) PowerPC-based machines: * Artesyn PM/PPC (NetBSD/pmppc) * IBM 6050/6070 (PReP, PowerPC Reference Platform) (NetBSD/prep) * MacPPC (NetBSD/macppc, HelenOS/ppc) SuperH-based machines: * Landisk I-O DATA USL-5P (NetBSD/landisk, OpenBSD/landisk) * Sega Dreamcast (NetBSD/dreamcast, Linux/dreamcast)

Other machine types and architectures are emulated less completely. See the documentation in the gxemul-doc package for the exact details and guides to installing guest operating systems.
