I got computation errors for tasks other than sixtrack (as you can see, two failed theory tasks are listed for that machine). lscpu shows VT-x. I even tried with Zorin 15 before this. I finally gave up and removed virtualbox and now only keep the machine for sixtrack but I would like to know why this keeps failing virtualbox applications. Any help appreciated.

The failed tasks were Theory native tasks which don't use VirtualBox. They failed because of a missing local CVMFS client. If you want to run Theory vbox tasks you need to reinstall VirtualBox, preferably a recent version from you Linux repository. Then disable "Run native if available?" at your prefs page: https://lhcathome.cern.ch/lhcathome/prefs.php?subset=project Since your computer has only 8 GB RAM it is recommended not to run ATLAS/CMS vbox (they require too much RAM).
