The scripts provided create the CMS virtual machine image based on CernVM, with CERN CentOS 7 (cc7).
CMS CC7 VM Image, for CMS MiniAOD open data from 2016 - 2018
First, you need to run a normal Micro-CernVM, using your own context so you can login. Copy the attached files to the running VM and then login.
Inside the VM, you need a copy of the latest Micro-CernVM release as a template for the Open Data image. Download the template ucernvm-v4prod.2020.07-1.cernvm.x86_64.hdd
from this record, inside the running VM placing it in the same directory as the other files.
Run the script:./cernvm-script
which will produce some output on the terminal, and then finish.
The result should be a file with the title coming from the -n field in the script, in this case:CMS-OpenData-1.6.0.ova
which can be copied from the running VM to elsewhere.
