This is extremely helpful. I only discovered virt-builder while debugging the issue with
ipv6 I reported a few days ago. Great little tool!
Thank you!

I've noticed that none of the images from virt-builder have
cloud-init in them by default. The documentation reads to me as if
the OS vendor's official cloud images are the ones used as the
sources for the generated images but I'm assuming this is wrong.
The problem with cloud-init is that it interrupts normal boot if
you're not booting the images in the cloud. However you can usually
add cloud-init by doing:
virt-builder --install cloud-init os-version
I know for a fact CentOS's cloud images from
https://cloud.centos.org/centos/7/images/ and Ubuntu's from
https://cloud-images.ubuntu.com/bionic/ have cloud-init installed
and enabled already.
Where are the images sourced from if not these official images?
The ones we supply are built using this script:
https://github.com/libguestfs/libguestfs/blob/master/builder/templates/ma...
The ones from SUSE are built using their build system. We'd like
other distros to build there own images for us, but no others do so
far.
I understand I can install cloud-init with virt-builder but I'm
trying to figure out what OS-distributed images are in use so I may
determine what else is different from expectations.
You can set up your own virt-builder repos, and populate them with
images from wherever you like, and if you want also disable the
official virt-builder repo. This will give you complete control over
what images get built. Have a look at the files in
/etc/virt-builder/repos.d, and the man page.
