[Go] virt-builder, to trivially create various Linux distribution guest images

I frequently use, part of the Libguestfs-tools package, as part of virt-builder 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 guest of size 100G, and of qcow2 format, it's as trivial as (no need for R Oot 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] Resi Zing (using Virt-resize) to expand, the disk to 100.0g[220.0] Opening the new disk[225.0] Setting a random seed[225.0] S etting random root password [did you mean to use--root-password?] Setting random password of root to n4kkqjztgdfjjqjj[225.0] finishing Offoutput:fedora-20.qcow2output size:100.0goutput Format:qcow2total 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
