Version information

Debugging on simulators that use Virtual Box (i.e. Xamarin Android Player, and Genymotion) hangs when the debugger tries to connect.  The app is properly installed on the device, and runs (i.e. after I disconnect from the debugger, I can browse to the app and launch it).

Steps to Reproduce:

1. Download and install either the Xamarin.Android player or Genymotion
2. Download an Android 4.4.x image
3. Download the Xamarin Field Service app (http://github.com/xamarin/prebuilt-apps), and open it in Xamarin Studio
4. Set FieldService.Android app as the startup app, and select your Android simulator to debug

Expected behavior: App starts and debugger connects

Observed behavior:  App starts, but hangs.  Debugger never connects.  Application output contains the following:

Verified on an x86 Google emulator, XAP, genymotion, and physical lollipop hardware.

@Saurabh I know there are issues with fastdev and emulators that do not have an sd card, please try to disable fastdev and deploy again.
