Hi @NicolasMarcos, Thank you for expressing your interest in downloading the Cloudera Quickstart VM. But unfortunately, the Cloudera Quickstart VM has been discontinued.
You can try the docker image of Cloudera available publicly on https://hub.docker.com/r/cloudera/quickstart or simply run the below command to download this on docker enabled system.
docker pull cloudera/quickstart
Please note, that Cloudera doesn't support QuickStart VM Officially and it's deprecated.
The up-to-date product is Cloudera Data Platform, and you can download a trial version to install on-premises here.
