As QEMU requires no host kernel driver to run, it is very safe and
easy to use.
For system emulation, only the x86 PC emulator is currently
usable. The PowerPC system emulator is being developped.
For system emulation, the following hardware targets are supported:
@itemize
@item PC (x86 processor)
@item PREP (PowerPC processor)
@end itemize
For user emulation, x86, PowerPC, ARM, and SPARC CPUs are supported.
