Installing an another OS with QEMU on Pardus
This document explains how to install and run QEMU with KVM support on Pardus.
Installation
Pardus->Programs->System->Konsole .
foto@turkuaz ~ $ sudo pisi it qemu kqemu
This command will install qemu and it's kernel-based virtualization module kqemu. Attention::
Statement: QEMU speed up module. This program is used only at non-profit usage, for other situations, you have to see the License files.
You must add kqemu module to /etc/modules.autoload.d/kernel-2.6 in order to install it at every startup.
foto@turkuaz ~ $ su Password: turkuaz foto # echo kqemu >> /etc/modules.autoload.d/kernel-2.6 turkuaz foto #
/etc/modules.autoload.d/kernel-2.6 file must like below;
1 | # /etc/modules.autoload.d/kernel-2.6: kernel modules to load when system boots.
2 | #
3 | # Note that this file is for 2.6 kernels.
4 | #
5 | # Add the names of modules that you'd like to load when the system
6 | # starts into this file, one per line. Comments begin with # and
7 | # are ignored. Read man modules.autoload for additional details.
8 | # For example:
9 | # 3c59x
10 | kqemu
Note: If you do not want to load kqemu module every startup, you don't have to load it at /etc/modules.autoload.d/kernel-2.6. But this will guide you to load kqemu module every startup. You must enter the commands below to load the module if you did not load it into etc/modules.autoload.d/kernel-2.6
foto@turkuaz ~ $ su Password: turkuaz foto # modprobe kqemu turkuaz foto #
Usage
Creating Virtual Disk
Create a virtual disk with the command below. You can change the size of the disk. This command will create a 5G sized disk.
foto@turkuaz ~ $ qemu-img create pardus.img 5G Formating 'pardus.img', fmt=raw, size=5242880 kB foto@turkuaz ~ $ ls
pardus.img
foto@turkuaz ~ $
pardus.img is ready for a new OS.
Installation of a New OS
Insert the CD of the OS that you want to install. You have not to mount the device. Write the commands below.
foto@turkuaz ~ $ qemu -soundhw all -localtime -hda /home/foto/pardus.img -cdrom /dev/cdrom -boot d
The command is that; It will install all sound drivers, will use local time, will use /home/foto/pardus.img for the disk usage, will use /dev/cdrom to use CDROM device and will boot the OS with CDROM.
The explanation of the argument in the command;
-hda argument gets the *.img
-cdrom argument gets the device which has the installation CD
-boot argument gets the boot device (a) floppy disk, (c) Harddisk, (d) CDROM
-localtime argument gets the local time usage
-m argument gets the size of the RAM which we will use with the new virtual OS
-soundhw arguments install the sound drivers
You may want to look http://www.qemu.org/qemu-doc.html for all of the arguments.
Another example (For fitting a monitor):
jnmbk@dell $ qemu -m 512 -soundhw all -localtime -hda pardus.img -cdrom /media/sda5/indirilen/pardus-1.1-alpha.iso -boot d -std-vga
Qemu has a feature to mount the ISO files to install an OS:
foto@turkuaz ~ $ qemu -soundhw all -localtime -hda /home/foto/pardus.img -cdrom /home/foto/pardus-1.0.iso -boot d
Note: You can use your mouse with clicking the Qemu window. In order to free your mouse, press Ctrl + Alt buttons at the same time. Use Ctrl + Alt + F to use full screen and use the same combination to exit from full screen.
change cdrom /dev/cdrom
Running The New Virtual OS
After the installation, eject the CD that is in you CDROM . Now, let's start our new and shiny virtual operating system.
foto@turkuaz ~ $ qemu -soundhw all -localtime -hda /home/foto/pardus.img
Yay!
