you can install the 4.3 Beta 1 and run your VMs. It will be possible to switch back to 4.2.16 if you don't have saved states for the VM involved. If you create any saved state with 4.3 (either by terminating a VM session by saving the state or by creating a snapshot while the VM is not powered off) you will not be able to restore such a state with 4.2.16. The other way around works: Saved states are backward-compatible but not forward-compatible. 4.3 will also introduce some new settings. 4.2.16 will not be able to read them and will just ignore them. So this shouldn't be a problem. Kind regards, Frank -- Dr.-Ing. Frank Mehnert | Software Development Director, VirtualBox ORACLE Deutschland B.V. & Co.
