Could someone help me im trying to run ubuntu 12.10 on qemu using windows 7 emulator but im stuck at these command steps

reparation of the QEMU virtual environment

QEMU is available as a standard package in the Universe repository. (There are on how to install packages elsewhere in this guide. Unlike some other virtualization systems (like VMWare), separate kernel modules are not needed.

Download the Ubuntu ISO file you wish to install into a virtual QEMU environment.

Recent QEMU versions support networking out of the box. There is a "linux-test" add-on at QEMU's site, a one-line script. Alternatively, run this command before starting the emulator: sudo /sbin/ip addr add 172.20.0.1/12 dev eth0

A virtual disk is needed for the virtual machine. A virtual disk is made by creating a file of a size appropriately large to contain the full guest OS:

qemu-img create ubuntu-test 3G

The 'qemu-img command (included in the QEMU package) creates a 3Gb image named 'ubuntu-test'. (qemu-img also supports other compressed and VMWare compatible disk-image formats.)

Another way of creating such images is using the standard dd utility:

dd of=ubuntu-test bs=1024 seek=4194304 count=0

This will create a 4GB file named ubuntu-test to use as a disk. bs is the blocksize, seek is the number of bytes to skip from start of the file being created (a multiple of 1048576 (or 1024K) ). In this case the image would be 4GB. If you wish to get a number to create another size, multiply the number of GB desired by 1024^2 or 1048576. So , 10GB would be 10x1048576 = 10485760.

Installation of an operating system from ISO to the QEMU environment

We are ready to install the guest OS. Download, for example, the latest development version of Ubuntu. Assuming your ISO image is named ubuntu-6.10-desktop-i386.iso for example:

qemu -hda ubuntu-test -cdrom ubuntu-6.10-desktop-i386.iso -m 192 -boot d

This command instructs QEMU to use hda as the empty disk file. It uses Ubuntu ISO file as if installing from the CDROM, and sets the amount of memory to use in the virtual machine to be 192Mb. It then instructs to boot from the CDROM.

A word of caution: giving too much memory to the virtual system will make your native host machine start swapping to disk, which will slow things down a lot. On the other hand, giving it too little memory will make the virtual machine start swapping, which will slow things down as well. Clearly, the more RAM you have, the better.

As the installer boots and goes through options, choose the defaults at each step. The installer should detect the virtual network properly and install without diificulties.

At the end, it will try to reboot the machine, but this will fail.

Exit the emulator (type "quit" in the emulator console), then rerun:

qemu -hda ubuntu-test -cdrom ubuntu-6.10-desktop-i386.iso -m 192

Note that the boot parameter is removed this time, so that it will boot ubuntu from the new virtual hard drive, not from the "cd".

Follow the directions from the installer and create a user. The installer will then fetch updates and add additional packages. This may take between one and two hours, depending on your system configuration and options chosen.

At one point, it will register all documentation for the help system.

Graphics display and adapter setup is very easy; the only question is what video modes to support. Leave this at the defaults; the virtual video hardware may not support higher resolutions than those already set.

where i type those stupid commands to run ubuntu? Please help
