7.9.5 Examples of Current Emulators and Virtual Machines
7.9.5.1 QEMU
QEMU [
93
] is a multi system emulator that emulates all aspects of a modern com-
puter system, including networking. It purports to be fast, in that emulation speeds
are in the order of 5-10 times slower than the original hardware (depending on the
instruction being executed). The following CPUs are emulated:
•
PC (x86 or x86_64 processor)
•
ISA PC (old style PC without PCI bus)
•
PREP (PowerPC processor)
•
G3 Beige PowerMac (PowerPC processor)
•
Mac99 PowerMac (PowerPC processor, in progress)
•
Sun4m/Sun4c/Sun4d (32-bit Sparc processor)
•
Sun4u/Sun4v (64-bit Sparc processor, in progress)
•
Malta board (32-bit and 64-bit MIPS processors)
•
MIPS Magnum (64-bit MIPS processor)
•
ARM Integrator/CP (ARM)
•
ARM Versatile baseboard (ARM)
•
ARM RealView Emulation baseboard (ARM)
•
Spitz, Akita, Borzoi, Terrier and Tosa PDAs (PXA270 processor)
•
Luminary Micro LM3S811EVB (ARM Cortex-M3)
•
Luminary Micro LM3S6965EVB (ARM Cortex-M3)
•
Freescale MCF5208EVB (ColdFire V2).
•
Arnewsh MCF5206 evaluation board (ColdFire V2).
•
Palm Tungsten
|
E PDA (OMAP310 processor)
•
N800 and N810 tablets (OMAP2420 processor)
•
MusicPal (MV88W8618 ARM processor)
•
Gumstix “Connex” and “Verdex” motherboards (PXA255/270).
•
Siemens SX1 smartphone (OMAP310 processor)
QEMU is quite capable of running modern complex operating systems including
Microsoft Windows XP (see Fig.
7.23
) as well as complex applications such as
Microsoft Word. 3D graphic programs would be problematic as it does not emulate
3D rendering graphics hardware. Many devices can be attached as it emulates USB,
Serial and Parallel interfaces as well as networking.
The source for QEMU is freely available under LGPL and BSD licences, and
extensive documentation exists on how QEMU works and how to port it to new host
systems. QEMU is geared towards speed over accuracy.
