QEMU
QEMU is an emulator for various CPUs. It works on Linux, Windows, FreeBSD and Mac OS X. It's possible to run grml with QEMU. Notice that it's much slower than running it native due to the emulation mode.
Using QEMU with acceleration
grml >=0.5 provides the accelerator module for QEMU namend 'kqemu'. Just run the following commands to use it:
apt-get update ; apt-get install qemu # install qemu modprobe kqemu # load the kernel module mknod /dev/kqemu c 250 0 # create the device chmod 666 /dev/kqemu /dev/net/tun # adjust permissions
To see if kqemu is enabled and working correctly, use the QEMU monitor command (press ctrl-alt-2): 'info kqemu'
Problems with Qemu
Black / blank screen
You get a black/blank screen when booting grml in qemu? Try booting with "grml vga=normal".
Running QEMU with grml on Linux
Install qemu (apt-get install qemu) and start it e.g. via:
qemu -m 256 -cdrom /dev/hdc # if running from CD-ROM qemu -m 256 -cdrom /path/to/grml.iso # if running from harddisk
Running QEMU with grml on Windows
First of all download QEMU for Windows. Download the grml-iso and put the QEMU files in the same directory as the grml-iso.
Now create a startup file, call it for example grml-qemu.bat:
REM Start qemu on windows. @ECHO OFF START qemu.exe -L . -m 256 -hdc harddisk -cdrom grml_0.6.iso CLS EXIT
Adjust the values if necessary and now run the grml-qemu.bat-file. Have fun :-)
