Put in the install CD and type into your konsole (all in one line without break): It just means that your new system is limited up to 10GB - if the new system takes only 1,2 GB also the image will only be at 1,2GB. Note: Even if you take 10GB this does NOT mean that the image does really HAVE the size of 10GB. Of course you are not obliged to take 5GB. Of course, this does not apply to 'qemu-img'. In the following examples where 'qemu' is, substitute your command for executing qemu. To discover the qemu commands that are installed perform the following: In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU.

User mode emulation (Linux host only).

It can be used to launch different Operating Systems without rebooting the PC or to debug system code. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation. Refer to Getting started with virtualization Qemu Any program that works on MS-DOS should also run on FreeDOS.QEMU is a very flexible virtualization technology however it is quite slow and it is recommended that you understand and evaluate alternative solutions before picking this one. Let’s try it with an example: installing a copy of the FreeDOS operating system. FreeDOS is an open source DOS-compatible operating system that you can use to run legacy business software and other DOS applications. Now that we have the essentials to start a virtual machine with QEMU, we can put it all together on a single command line to create and boot your virtual machine! For example, set -boot order=dc to tell QEMU to try the CDROM ( d ) first, then the hard drive ( c ). Use -boot to specify the order that QEMU should look for bootable devices. You can also append a suffix of M or G to specify the memory in MB or GB. If you do not explicitly set this, QEMU defaults to 128 MB. Set the amount of memory in the virtual machine with the -m size option. For example, this might be the bootable ISO image to install Linux, Windows, or another operating system. Set -cdrom isofile to define the CD-ROM or DVD image file. This should be the same virtual disk you defined with the qemu-img command. Use -hda imagefile to tell QEMU to use imagefile as the hard drive image. To emulate a more modern system, use qemu-system-x86_64. To emulate a legacy PC system, use qemu-system-i386.
