metadata.abstract.description: The virtual machine image is based on CernVM (cernvm.cern.ch), with Scientific Linux CERN 5 (slc5), which is the environment needed for the CMSSW release to be used with the 2010 CMS open data. It gets the CMS software (CMSSW) from /cvmfs/cms.cern.ch. Access to the data is through XRootD. The "CMS-OpenData-1.1.4.ova" version is recommended, it has an embedded slc5 shell, where all CMS software specific commands should be executed. Additionally, it has a slc7 shell, which can be used in the same session. It has a 20G virtual hard disk and a 10G cvmfs cache and can read the condition data from /cvmfs/cms-opendata-conddb.cern.ch.
