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 įor 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.Īurélien 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 8 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.
