Hi Giuseppe!
I saw you mentioned you have sysadmin knowledge and some python too, would you be interested in helping with devops tasks for the oVirt infra team [1] ?
The infra team is in charge of maintaining the entire devops infrastructure with jenkins as the 'ci' server in the middle.
You can also checkout the monthly emails in the devops section. [2]
In addition, you can contribute python code to a recent independent project which came out of oVirt called 'lago',
you can read about it here [4].
Let know if this is something you might be interested in, you can check some of the tasks we're doing in [3].
