QEMU is a process that gives to o.s.guest a virtual hw

Every guest will be run by a QEMU instance.

See picture schema I prepaired: http://yfrog.com/7gqemulayersj

QEMU receives a system call and software emulator
QEMU performs a system call in O.S. host.

No, guest system calls are handled by the guest OS.
