The cld-build.cloud.pd.infn.it is the machine to build images for VM. It is available for users too if they want to create their own images. If an user asks for an account, you need to log in the machine as root (ask to M.Sgaravatto the password) and to create the account adding the user to the ozusers group. And create a password to change at the first login
adduser <username> -G ozusers passwd <username>
Then the user has
[paths] output_dir = /tmp/<username>/oz/images data_dir = /tmp/<username>/oz/data screenshot_dir = /tmp/<username>/oz/screenshot [libvirt] uri=qemu:///system [cache] original_media = yes modified_media = no jeos = no
mkdir -p /tmp/<username>/oz/images /tmp/<username>/oz/data /tmp/<username>/oz/screenshot
chown o+rx /tmp/<username>/oz/images
