If i remember correctly, when you create a virtual machine you set it's
disks to be normal (all changes are written to the image file),
persistent? (all changes are written to a secondary file), and i think
there's a third one I'm forgetting.

with normal it is just like using a real machine.  updating a package
will update the disk image.

but with the other option all changes are written to a journal.  As the
vm runs looks for files it looks first at the journal file and then at
the disk image.  It is sorta like unionfs in Linux.

When you look at the files there is another one sitting next to the disk
image files.  In addition if you suspend the machine (workstation only)
there is yet another file that holds the contents of ram etc.

In the old version where they did not have Teams, you had to copy these
files around and use hardlinks/softlinks to conserve disk space.  If you
get a base install that is 600M and then want to use it to try out
different versions of a package, you make a link to the base disk images
and use the persistent disk feature so that all changes are written to
extra files.  I put them in separate directories named based on the
package I was trying.

I have not used Teams but suspect they manage this process for you and
make it cleaner.
