Projects / QEMU


QEMU is a fast processor emulator. Using dynamic translation it achieves a reasonable speed while being easy to port to new host CPUs. In its user mode emulation mode, it can launch Linux processes compiled for one CPU on another CPU. Linux system calls are converted because of endianness and 32/64 bit mismatches. In its full system emulation mode, it emulates a full system, including a processor and various peripherials.

            Great stuff
            I just had to post a comment... I really like this software, I develop a linux distribution, and aid in the development of a few other projects, and having the ability to test installs without messing up my original system is very helpful. QEMU was easy to install, and is very easy to use. Even the accelerator was easy to install and use. 10 stars!
