Yup, it's using the physical partition, so all changes are preserved. Whether you want that or not. I suppose you could use a snapshot VMDK to put the FS changes into a file, which you could then keep or discard. No idea if VBox or even VMWare actually supports this behaviour. Nor can I think of any particularly good use for it!
