how to run a scheduler with virtualenv

[A3]

Currently I run Web2py using wsgi / Apache using virtualenv in the wsgihandler.py 

I also  use a scheduler using  web2py.py --nogui -K myap

Sofar I didn't pay attention to the virtualenv  as I didn't have any problems.  

Probably because the python version in the virtualenv is equal to the system python version.

I wonder how I can easily use the same virtualenv for the scheduler?

Is it simple like this: 

  source ./python_env/bin/activate

  web2py.py --nogui -K myap

?
