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

73 <p>First of all download <a href="http://www.h7.dion.ne.jp/~qemu-win/">QEMU
74 for Windows</a>. <a href="/download/">Download
75 the grml-iso</a> and put the QEMU files in the same directory as the
78 <p>Now create a startup file, call it for example <a
79 href="grml-qemu.bat">grml-qemu.bat</a>:</p>
82 REM Start qemu on windows.
84 START qemu.exe -L . -m 128 -hdc harddisk -cdrom grml_0.6.iso
88 <p>Adjust the values if necessary and now run the grml-qemu.bat-file. Have fun
