NAME

       fai-diskimage - create a disk image for booting a VM

SYNOPSIS

       fai-diskimage imagename

DESCRIPTION

       fai-diskimage creates a disk image that can be used with Qemu/KVM, VirtualBox, VMware, Xen
       or by your cloud infrastructure. It runs the Fully Automatic Installation using a list  of
       FAI classes. In the end you have a bootable disk image.

OPTIONS

       -c, --class CLASS[,CLASS]
              Define list of FAI classes

       -D, --debug
              Enter  debugging  after  the  FAI process has finished. Therefore the fai-diskimage
              script is stopped and  you  may  enter  the  chroot  for  debugging  purpose.  When
              finished,  leave  the  chroot and send a CONT signal for resuming the fai-diskimage
              script.

       -h, --help
              Print help

       -N, --new
              This option will be passed to the  fai  call.  It  then  executes  the  scripts  in
              class/[0-9]* for defining classes.

       -S, --size SIZE
              Set size of raw image (suffixes k M G T are supported)

       -s, --cspace URI
              Location of the config space. If location starts with /, the prefix file:// will be
              added. See fai.conf(5) for all supported protocols. Default is /srv/fai/config.

       -u, --hostname name
              Set hostname to name

       -v, --verbose
              Be verbose

EXAMPLES

        # export FAI_BASEFILEURL=http://fai-project.org/download/basefiles/
        # fai-diskimage -vNu cloud3 -S2G -cJESSIE64,GCE disk.raw

       Creates a Debian system with a small set of software packages without  graphical  desktop.
       The disk image disk.raw will be of size 2 GB and the host ist called cloud3.

        # export FAI_BASEFILEURL=http://fai-project.org/download/basefiles/
        # cl=DHCPC,UBUNTU,XENIAL,XENIAL64,XORG
        # fai-diskimage -vNu cloudhost -S5G -c$cl ubuntu.qcow2

       Creates a disk image of size 5GB called ubuntu.qcow2 for a Ubuntu 16.04 desktop.

NOTES

       Before creating an image, make sure you have the configuration space available. Create the
       config space for FAI by using the examples from the fai-doc package.

        # mkdir -p /srv/fai/config
        # cp -a /usr/share/doc/fai-doc/examples/simple /srv/fai/config

       fai-diskimage is not limited to creating images for virtual machines. The raw  images  can
       also be copies (via dd) onto a real disk for booting bare metal hosts.

       You can start fai-diskimage in a clean shell environment by calling:

        # env -i /usr/sbin/fai-diskimage -vNu cloudhost -S5G -cJESSIE64,GCE disk.raw

       information on how to use fai-monitor.  The FAI homepage is http://fai-project.org.
