What does this mean? Will I loose anything if - for example - there is
not enough space on the target device? Or it will still use the original
disk image?

AFAIK, a transient guest only means it will disappear after the
virtualisation session ends.

I could not find anything about "pivot" or "pivoting"? What does --pivot
do in this case?


Thank you.
