Is that the case? If so is there a way to tell Virtual Box to completely kill a virtual machine so it doesn't use resources until I next start it up?
When you put the guest into the Saved
state, whatever is in memory (RAM) of the guest is written to your hard drive as a (date-and-bunch-of-numbers.sav) file. So when you start it up again it loads that file into memory again, allowing it to start up much faster than a full OS boot-up. How much drive space is used depends on how much memory your guest was using at the time it was put into the Saved
state, up to your allotted 1.5GB. If you shut down the guest it does not write this file. In either case your Mac's RAM is not being used when the guest is not running.
