Oz is a tool for automatically installing guest OSs with only minimal up-front input from the user.

For each type of guest operating system, Oz supports up to three operations: operating system installation (oz-install), operating system customization (oz-customize), and ICICLE manifest generation (oz-generate-icicle).

Currently many versions of popular operating systems are supported, including Debian, Ubuntu, RHEL/CentOS, Fedora, openSUSE, Mandrake, and FreeBSD. See also virt-install(1) and virt-builder(1) from the virtinst and libguestfs-tools packages.
