Running python from a mounted filesystem
One solution I found was to mount my shared folder with cifs into the VM. That seems to work flawlessly. I did not found a solution for the vboxsf.
I have a django-based application that I'm running from a virtualbox-shared folder. When starting using 'runserver' I get an error indicating that a module could not be found. After copying the same exact code to a directory on the local filesystem, it starts and runs as expected.
Anyone seen anything like this when working with virtualbox and python? 
It appears that module resolution is working differently when python is run from the mounted shared folder vs. the local folder, but I can't find a smoking gun that indicates whether or not it's caused by how that folder is mounted or python.
Thanks!
