libvirt users - Sep 2010 - KVM guest creation - no manual interference

Hi

I've looking for a way to create KVM virtual machines completely automated
without the need to interact with guest operating system during
installation.

With ubuntu-vm-builder is possible create the guest, list packages to be
installed and scripts to be run. Is there a way to do something like it with
libvirt?

Thanks!

I wrote Cucumber-VHost for exactly this purpose.

We use Cucumber-VHost and puppet as well as cobbler and Hudson to completely 
automate the build and testing of our configuration files.

Cucumber-VHost creates a virtual machine based on it's definition in cobbler
and a plain english script invoked by Rake.

More details are on my blog at http://www.threedrunkensysadsonthe.net/ and in 
GitHub: http://github.com/proffalken/cucumber-vhost

HTH,

I've (just today) achieved this using virt-manager, built on top of libvirt,
for centos guests at least, defining a mirror URI for the kernel and initrd
images, and a kickstart URL, having written a kickstart script for anaconda
and stored it on a webserver ahead of time.

virt-manager is packaged in Debian/Ubuntu too.

I haven't built any Debian/Ubuntu VMs yet, but I would basically do the same
thing but using debconf preseeding for automated Debian installations.
