Unable to create Genymotion Virtual Device

Question

I have successfully downloaded and installed Genymotion and Virtualbox as well as a Virtual Device Image but I am unable to create a virtual device.
I get an error messa

Answer 1

I solved the issue deleting the deployed images in

~/.Genymobile/Genymotion/deployed

I didn't touch ova files

Answer 2

I also had the issue. Had to delete Genymotion cached files/devices then redownload devices and reinstall.

Answer 3

Solved!!

I am using OS X 10.9 (Mavericks), Genymotion v1.3.1

While adding the device, instead of adding Nexus, I added Galaxy S4/HTC One/Xperia Z - 4.2.2 with Google Apps.

This one just worked.
