On Linux systems, you can usually use a logical device name like /dev/cdrom or /dev/dvd, or the physical name of the device, e.g. To boot from a real CD or DVD, tell QEMU where to find it. Note: Depending on your distribution, you may need to use qemu-system-x86_64 command (when you using a 64-bit OS, also if you want to use KVM later). Qemu -m 256 -hda winxp.img -cdrom winxpsp2.iso -boot d We'll also give it 256В MB of RAM, but we won't use the kqemu kernel module just yet because it causes problems during Windows XP installation.

Here we'll boot off an ISO image of a properly licensed Windows XP boot disc. Many free operating systems can be downloaded from the Internet as bootable ISO images, and you can use them directly without having to burn them to disc.

The easiest way to install a guest OS is to create an ISO image of a boot CD/DVD and tell QEMU to boot off it. Here we'll create a 3В GB qcow2 image to install WindowsВ XP on: The 'native' format for QEMU is qcow2, and this format offers some flexibility. If you don't tell it what format to use, it will use raw files. QEMU has the qemu-img command for creating and manipulating disc images, and supports a variety of formats. To set up your own guest OS image, you first need to create a blank disc image.

On filesystems that support sparse files, images in this format only use the space actually used by the data recorded in them. Raw (default) the raw format is a plain binary image of the disc image, and is very portable. QEMU currently can use these image types or formats: The 'native' and most flexible type is qcow2, which supports copy on write, encryption, compression, and VM snapshots. 6 Copying an image to a physical device.Also turn off video and sound and if using qemu-system-sparcw.exe then change the filename to qemu-system-sparc.exe because some renamed it. If you are using the manager program for windows then just add the 'root=/dev/ram/' in the advanced tab. This is specifically true for the Sparc test files available from, but probably for some of the others as well. This will then cause the test system to work. If so then specify 'root=/dev/ram' as an addition kernel command line option. They can be found at ДЇor some of the test kernels that you get, for example, the Sparc test image, you might get the error 'No NFS Server available giving up' or some other message about needing to insert a 'Root Floppy' or even a message specifying to fix the root option.

To make QEMU release your mouse again, hold down the Control and Alt keys simultaneously, then let go - your mouse will be released back to X.ДЄurГ©lien Jarno of Debian has prepared a number of pre-packaged Debian QEMU images for several architectures, including ARM, Sparc, PowerPC, x86_64, and i386. If it has a GUI and you want to use your mouse with it, double-click on the window and QEMU will grab your mouse. Replace linux-0.2.img with the name of your guest OS image file. When you do not have the plain command qemu try to run:

To run it, download and unzip the image in a folder and run the QEMU command.

You can download a few guest OS images from the QEMU website, including a simple 8В MB image of a Linux distro (which is meant primarily for testing note that it lacks the e1000 driver and therefore cannot do networking out-of-the-box). From the perspective of the guest OS, it actually is a hard disk, and it can create its own filesystem on the virtual disk. This image is a file that represents the data on a hard disk. Once QEMU has been installed, it should be ready to run a guest OS from a disk image.
