How to create websites in shared folder using quickstart?

Question

I am using quickstart and I am able to create websites, run all drush commands, etc.

I am running Virtual Box on a Windows7 machine. i have setup a folder to be shared.

My problem: I am not able to create drupal sites (using drush qc --domain=mysite.dev") in that shared folder.

I want to create in that shared folder since I need access to the files from my windows environment also - for backup purposes, etc.

My terminal Output:

12:51:05 ~$ cd Desktop/
12:51:12 ~/Desktop$ cd shared
12:51:14 ~/Desktop/shared$ ls
DrupalPro_test.ova
12:51:15 ~/Desktop/shared$ drush qc --domain=neil.dev
                                                                     [ok]
