In Ohai 7, the ohai plugin name is not the plugin file name, but defined in the plugin file. Here is what I used in Ohai 7.0.4 :
Ohai::Config[:disabled_plugins] = [:Azure, :Filesystem, :Cloudv2, :Virtualization, :Virtualizationinfo, :Dmi, :Zpools, :Blockdevice, :Lsb, :Nodejs, :Languages, :Php, :Lua, :Perl, :C, :Java, :Python, :Erlang, :Groovy, :Ruby, :Mono, :Os, :Openstack, :Cloud, :Rackspace, :Ps, :Command, :Initpackage, :Rootgroup, :Keys, :Sshhostkey, :Ohai, :Chef, :Ohaitime, :Passwd, :Gce, :Systemprofile, :Linode, :Ipscopes, :Eucalyptus, :Ec2]
