If you have installed all the neccessary python packages on your
local host, then it is entirely possible to run the Nova test
suites without using virtualenv. You just need to pass the '-N'
arg to the run_tests.sh script, eg on my Fedora 17 host, I can
run

   ./run_tests.sh -N nova.tests.test_libvirt
