This creates a tar file of about 320M (supposed that the image contains a 1.9GB ext3 root filesystem and a 250MB swap partition). After installing a Debian base system, it fits on a CD-ROM even without compression: $ tar c -sparse -f backup.tar debian.img The disk image 'debian.img' is a sparse file.

Install the system as usual to set up a sid system choose 'unstable' when being asked by the installer.Īfter the installation is done, the system can be booted with: $ qemu-system-x86_64 -hda debian.img -m 512.

When the usual debian boot screen appears, boot into 'expert' mode.

If you have KVM, you can use it by including the option -enable-kvm.

If you're installing a desktop environment, you'll need more than 2G. A sid system can be set up with the following steps:Ĭreate the hard disk image with: $ qemu-img create debian.img 2G QEMU is especially handy to set up an emulated testing/unstable system when working on the Debian installer itself or on the boot system, or when trying some experimental features without impact on the productive system. The QEMU emulator is packaged as per-CPU-type packages: $ sudo apt install qemu-utils qemu-system-x86 qemu-system-guiĭebian developer Aurelien Jarno maintains a list of ready-to-use Debian stable QEMU images at (but as of, there is no update since 2015). + granting the user R/W access to /dev/kvm + x86 and ARM CPU w/ virtualization extensions
