31 <p><a href="http://fabrice.bellard.free.fr/qemu/">QEMU</a> is an emulator for
32 various CPUs. It works on Linux, Windows, FreeBSD and Mac OS X. It's possible
33 to run grml with QEMU. Notice that it's much slower than running it native
34 due to the emulation mode.</p>
36 <h2>Using QEMU with acceleration</h2>
38 <p>grml >=0.5 provides the <a
39 href="http://fabrice.bellard.free.fr/qemu/">accelerator
40 module</a> for QEMU namend 'kqemu'. Just run the following
41 commands to use it:</p>
44 apt-get update ; apt-get install qemu # install qemu
45 modprobe kqemu # load the kernel module
46 mknod /dev/kqemu c 250 0 # create the device
47 chmod 666 /dev/kqemu /dev/net/tun # adjust permissions</pre>
49 <p>To see if kqemu is enabled and working correctly, use the QEMU monitor
50 command (press ctrl-alt-2): 'info kqemu'</p>
52 <h2>Problems with Qemu</h2>
54 <h3>Black / blank screen</h3>
56 <p>You get a black/blank screen when booting grml in qemu? Try booting with "grml vga=normal".</p>
58 <h2>Running QEMU with grml on Linux</h2>
60 <p>Install qemu (apt-get install qemu) and start it e.g. via:</p>
63 qemu -m 256 -cdrom /dev/hdc # if running from CD-ROM
64 qemu -m 256 -cdrom /path/to/grml.iso # if running from harddisk
67 <h2>Running QEMU with grml on Windows</h2>

72 <p>First of all download <a href="http://www.h7.dion.ne.jp/~qemu-win/">QEMU
73 for Windows</a>. <a href="/download/">Download
74 the grml-iso</a> and put the QEMU files in the same directory as the
77 <p>Now create a startup file, call it for example <a
78 href="grml-qemu.bat">grml-qemu.bat</a>:</p>
81 REM Start qemu on windows.
83 START qemu.exe -L . -m 256 -hdc harddisk -cdrom grml_0.6.iso
87 <p>Adjust the values if necessary and now run the grml-qemu.bat-file. Have fun
