SUMMARY="A generic and open source machine emulator and virtualizer"
DESCRIPTION="QEMU is a generic and open source machine emulator and virtualizer.

QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a \
different machine (e.g. your own PC). By using dynamic translation, it \
achieves very good performance."
