Copy-Paste from Mac to Emacs of ubuntu

I use version 10.9.2 of OS X and a virtual machine 6.0.5 VMware Fusion. Ubuntu 14.04 LTS has been installed on the virtual machine. In ubuntu I use Emacs 24.3.1 as editor.

Once emacs of ubuntu is launched, the Kill Menu (see Edit -> Paste from Kill Menu) is empty. If I want to copy a text from Chrome under Mac to Emacs under ubuntu, I can use Command+C (which saves the text into the Kill Menu of Emacs) then Command+V or Ctrl+V.

I can also copy and paste a text within Emacs by using Command+C (which also saves the text into the Kill Menu of Emacs) then Command+V or Ctrl+V.

However, the problem is, after I copy and paste something within Emacs, I could not copy and paste a test from Mac to Emacs anymore by Command+C then Command+V or Ctrl+V: Command+C under a Chrome page of Mac can not save the text into the Kill Menu anymore. Consequently, Command+V or Ctrl+V within Emacs always pastes the last element in the Kill Menu, which is not what I want.

So I have to close and re-launch Emacs to clean the Kill Menu to enable the copy-paste from Mac to Emacs of ubuntu, which is tedious...

Could anyone help?
