Calling pip command inside a virtualenv should list the packages visible available in the isolated environment  Make sure to use a recent version of virtualenv that uses option --no-site-packages by default  This way the purpose of using virtualenv is to create a python environment without access to packages installed in system python   Next  make sure you use pip command provided inside the virtualenv  YOUR ENV bin pip   Or just activate the virtualenv  source YOUR ENV bin activate  as a convenient way to call the proper commands for python interpreter or pip    Projects  virtualenv --version 1 9 1    Projects  virtualenv -p  usr bin python2 7 demoenv2 7 Running virtualenv with interpreter  usr bin python2 7 New python executable in demoenv2 7 bin python2 7 Also creating executable in demoenv2 7 bin python Installing setuptools                            done  Installing pip               done     Projects  cd demoenv2 7    Projects demoenv2 7  bin pip freeze wsgiref  0 1 2    Projects demoenv2 7  bin pip install commandlineapp Downloading unpacking commandlineapp Downloading CommandLineApp-3 0 7 tar gz  142kB   142kB downloaded Running setup py egg info for package commandlineapp Installing collected packages  commandlineapp Running setup py install for commandlineapp Successfully installed commandlineapp Cleaning up       Projects demoenv2 7  bin pip freeze CommandLineApp  3 0 7 wsgiref  0 1 2   What s strange in my answer is that package  wsgiref  is visible inside the virtualenv  Its from my system python  Currently I do not know why  but maybe it is different on your system

You can list only packages in the virtualenv by pip freeze --local or pip list --local  This option works irrespective of whether you have global site packages visible in the virtualenv   Note that restricting the virtualenv to not use global site packages isn t the answer to the problem  because the question is on how to separate the two lists  not how to constrain our workflow to fit limitations of tools   Credits to  gvalkov s comment here  Cf  also this issue
