QEMU is a free x86 emulator for Linux and Windows. A preloaded QEMU image of ReactOS can be found here.
If you are looking for a faster virtual machine, give VirtualBox or VMware a try.
Contents
Installing ReactOS on QEMU
- Create a drive image, on which ReactOS will be installed, by typing:
qemu-img create ReactOS.img 1000M
1000M stands for 1000 megabytes- that shall be enough. It shall be greater, if you plan to install some application to try under ReactOS.
- In *nix only, type:
sudo umount /dev/shm sudo mount -t tmpfs -o size=144m none /dev/shm
- Type:
qemu -L . -m 256 -cdrom ReactOS.iso -hda ReactOS.img -boot d -localtime -serial file:ReactOS.log
-m 256 stand for 256 MB RAM -boot d instructs QEMU to boot from the CD-ROM. Without -boot d it will boot from the hard drive (Reactos.img).
ReactOS.iso is the image of the installation CD, which can be downloaded from http://www.reactos.org/en/download.html
When reinstalling ReactOS, perform steps 2 (if necessary) and 3 only.
If you want to copy some files to ReactOS, you could create an CD-ROM image and mount it on QEMU. You can run QEMU this way:
qemu -L . -m 256 -cdrom Applications.iso -hda ReactOS.img -localtime -serial file:ReactOS.log
Setting up Sound
Using AC97 emulation (QEMU 0.10.1 or later)
- Set emulation to AC97 (-soundhw ac97)
- Install the drivers using Downloader! (You need to reboot twice)
Known Issues
- Audio sounds glitch when changing the audio stream with a high sample rate to a stream with low sample rate
Using ES1370MP emulation
- Set emulation to ES1370 (-soundhw es1370)
- Install drivers from here [1]
- Create a file named import.reg with the following contents

"LineOutVol_Left"=dword:fff9f203
"LineOutVol_Right"=dword:fff9f203
"LineOutMute"=dword:00000000
- Import those settings by starting cmd.exe and regedit import.reg
- Reboot
If you don't hear any sound in QEMU 0.10.x, you'll have to set QEMU_AUDIO_DRV=fmod (available: dsound; fmod; sdl; none ; wav (dump to file) – see QEMU documentation for information.
Known Issues
After starting first audio stream, you need to leave QEMU and re-enter (seems to be a QEMU bug)
Setting up network
Networking should work by itself using the '-net nic,model=ne2k_pci' and '-net user' switches with QEMU.
Using ReactOS LiveCD on QEMU
- Move to the previously created directory with the
cd
command. - There, type in the following command:
qemu -L <Path to your QEMU folder>\bios -cdrom <filename>.iso -m 64
Grabbing debug messages
By default, ReactOS debug messages are sent to the serial port (COM1). For grabbing that output, you need QEMU version 0.6.1 or later, in which you can specify the -serial option.
Valid arguments to -serial include file names, pipes, COM Ports and more. Those arguments could be:
-serial file:"C:\roslog.txt" -serial pipe:"\\pipe1\" -serial COM4
Redirect to a file
If you're using the QEMU virtual machine and want to redirect the serial output to a file, add the following to your QEMU command line:
-serial file:FILENAME
Replace FILENAME with the name of a file, into which the debug output shall be written.
Redirect to the console
The method above redirects the output to a file. If you want to redirect it to the console, there are two different methods. They depend on the operating system you run QEMU under.
- Under Windows, add the following to your QEMU command line:
-serial file:CON
- Under a Unix-based operating system, add the following to your QEMU command line:
-serial stdio
Serial port connection using com0com
Setup the com0com driver like explained in this com0com guide.
Add the following option to your QEMU command line
-serial COM4
Write "COM4" with capital letters otherwise QEMU won't use the serial port at all!
Open your terminal program and start a new connection to your second virtual port. If that port is not listed, try COM4.
Another option is to use the ReactOS Test Environment instead of setting this up manually.
KQEMU
If you feel that QEMU is too slow for you, consider using the KQEMU module.
Pleas bear in mind that it just works with QEMU up to 0.11 and isn't maintained anymore.
