Saving Virtualbox state during dist-upgrade?

view story

http://askubuntu.com – I am wondering if I am going to do any harm to my virtual system if I save it's state and close the VM while it is in the middle of a dist-upgrade? Afaik saving the state allows you to resume it with the system being unaware that anything has even happened, so am I safe to Save state and close? (HowTos)
