Another bit of advise, that will also save much typing, much
disc-space, and
many headaches is "Don't Save Snapshots." Sure if you have something critical
that you think will thrash your install, then make a snapshot, make the
changes and see if they work, then "discard" the snapshot to merge all changes
and consolidate back to a single disk without any snapshots.
Then you save all the disc space (which can double your vdi size), you
eliminate all cloning headaches and greatly simplify everything.
Remenber, you can merge several earlier snapshots into one by
right-clicking
on a "snapshot" (NOT THE "Current State") and selecting "Discard snapshot".
I used to keep snapshots religiously. I would have 4, 5 or 6 snapshots
capturing different software states thinking that is what you were supposed to
do. Then I thought -- "What for??" If you have your machine in a state you
like, then just discard all your snapshots and backup you VDI. If you can't
backup your vdi, then keep make "1" snapshot before doing something crazy,
then when you have successfully made the changes, discard the snapshot and
carry on. If things go to hell, then "Revert" the "Current State" and you are
back to your snapshot, then carry on.
At least for me, carrying snapshots ended up just making things more
difficult and the chance I would ever go back to snapshot "#4"' was nil.
