I frequently use virt-builder (part of libguestfs-tools package) as part of my work flow.

Rich has extensively documented it, still I felt it’s worth pointing out again of its sheer simplicity.

For instance, if you need to create a Fedora 20 guest of size 100G, and of qcow2 format, it’s as trivial as (no need for root login):

$ virt-builder fedora-20 --format qcow2 --size 100G
[   1.0] Downloading: http://libguestfs.org/download/builder/fedora-20.xz
#######################################################################  100.0%
[ 131.0] Planning how to build this image
[ 131.0] Uncompressing
[ 139.0] Resizing (using virt-resize) to expand the disk to 100.0G
[ 220.0] Opening the new disk
[ 225.0] Setting a random seed
[ 225.0] Setting random root password [did you mean to use --root-password?]
Setting random password of root to N4KkQjZTgdfjjqJJ
[ 225.0] Finishing off
Output: fedora-20.qcow2
Output size: 100.0G
Output format: qcow2
Total usable space: 97.7G
      Free space: 97.0G (99%)

Then, import the just created image:

$ virt-install --name guest-hyp --ram 8192 --vcpus=4   --disk path=/home/test/vmimages/fedora-20.qcow2,format=qcow2,cache=none   --import

It provides a serial console for login.

You could also create several other distribution variants – Debian, etc
