SOLVED ------ OPERATOR ERROR!!!! version 4.2.16 (latest linux version of VBox) I thought about putting this in the virtualization forum but its specific to 14.04 (Ubuntu). I have been having issues with guest additions on a 14.04 VM. The screen won't resize. When I read on the VB forums it is addressed in version 4.3.10 but that is only for windows apparently. I guess I will just have to keep using my 12.04 VM's until VB releases a new version compatible with 14.04. Latest for 13.10 host is 4.2.16. Everything works like "clockwork" using 13.10 host and 12.04 VM's.
