"I'm Using Windows 10 Host and Ubuntu 14.04. I solved the problem by Deleting the ""Right Ctrl"" key from the list of shortcuts reserved by VB.
In the VB's menu got to:

File->Preferences->Input->VirtualMachine

||Name||Shortcut||
|Host Key Combination|Right Ctrl|

Delete this shortcut and that's it!"
