pycharm remote debugging + virtualenv

I am struggling to get a working setup.

Here is what I am trying to accomplish:

- pycharm on windows
- virtualenv/code on a network share

I would like to be able to execute the code on a remote linux server. I have been able to configure the remote interpreter via ssh. I try to set the starting script as "pytest" but I always get

env/bin/python -u /phaedrus/home/kfowler/.pycharm_helpers/pydev/pydevd.py --multiproc --qt-support --client '0.0.0.0' --port 45009 --file pytest --help
warning: Debugger speedups using cython not found. Run '"/phaedrus/home/kfowler/eureka_repo/eureka_env/bin/python" "/phaedrus/home/kfowler/.pycharm_helpers/pydev/setup_cython.py" build_ext --inplace' to build.

Traceback (most recent call last):

buffer = _builtin_open(filename, 'rb')
FileNotFoundError: [Errno 2] No such file or directory: 'pytest'

I believe this may be because the "pytest" package is only installed within the virtualenv but for some reason it is not actually picking that up.

Is there something I am doing wrong here?
