Exemple:

 

@ECHO OFF

REM Start qemu on windows.

 

SET SDL_VIDEODRIVER=directx

 

REM QEMU_AUDIO_DRV=dsound or fmod or sdl or none can be used. See qemu -audio-help.

REM Starting on the iso image for installing Fedora 10 can be done by adding:

REM    -boot d -cdrom Images/F10-i686.iso

 

qemu.exe -L Bios -m 1024 -name Fedora10 -hda Images/fedora10.img -vga std -soundhw es1370 -localtime -M pc -net nic,model=e1000 -net user -redir tcp:5555::23 -redir tcp:5556::22

 

Changing a CD-ROM image

To change a CD-ROM image, please use QEMU Monitor:

·        To see the Monitor, press Ctrl-Alt-2 keys together.

·        To go back to the guest OS, press Ctrl-Alt-1 keys.

·        With the latest GTK user interface the console is now available in the View menu as compatmonitor0

·        And going back to the guest OS window in the View menu as VGA

 

(qemu) eject ide1-cd0
(qemu) change ide1-cd0 filename.iso

 

Note:

·        Please use slash instead of back slash in the QEMU Monitor window.

·        Path of the filenames is relative to the directory where qemu.exe lives.

·        You can see the status of the block devices with:

 

(qemu) info block

ide0-hd0: test-i386/hda.qcow2 (qcow2)
    Cache-mode:      writeback

ide1-cd0: Images/os.iso (raw, read-only)
    Removable device: not locked, tray closed
    Cache mode:       writethrough
../..
