The virtual machine image is based on CernVM (cernvm.cern.ch), with Scientific Linux CERN 6 (slc6), which is the environment needed for the CMSSW release
to be used with the 2011 CMS open data. It gets the CMS software (CMSSW) from /cvmfs/cms.cern.ch and the jobs running on the CMS open data VM read the condition data from /cvmfs/cms-opendata-conddb.cern.ch. Access to the data is through XRootD.
How can you use this?
