So as long as you shut down your VM safely, you will be able to use the same .vdi image with 1.5, 1.6 and 2.0.0 (I do this every day). Second, the saved states should be compatible between 1.6 and 2.0.0. We are trying hard to not break the saved states anymore. The only thing which changes is the xml format of the machine description. So if you experience any problems during upgrade or downgrade you can just create a new VM, detach the hard disk from the old VM and attach it to the new VM. For Windows guests make sure you use the same settings for I/O APIC, PIIX3/4 and ACPI. Other settings should not make any matter and Linux guests don't care anyway. If you upgrade from 1.5 to 1.6 or 2.0.0 then the GUI will ask you for conversation of the .xml files the first time you start it. Press 'backup' to keep the old .xml files around. In case you want to downgrade you can use the saved backup files. If you upgrade from 1.6 to 2.0.0 and start a VM, the machine description will contain new elements after the VM settings were saved or after the VM terminates. If you try to start the same VM with 1.6 now this will not work as 1.6 does not understand the new 2.0 elements. Manual edition of the .xml file is required -- just remove the two superflous elements and press the 'Refresh' button. This is kind of annoying and we are aware of this but currently there is no other way to downgrade. Kind regards, Frank -- Dr.-Ing. Frank Mehnert Sun Microsystems http://www.sun.com/
