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
