as title, I know there're two snapshots in qemu, but I don't know when to
use them well.
What I know is internal snapshot will save the info of L1 and L2 table in
the end of image but external snapshot won't because external snapshot
create new file to save cow data.
So when to use internal snapshot or external snapshot?
In general, we've spent more resources developing external snapshots. So
if you want the most support and the fastest response on resolving any
issues that you may encounter, external snapshots are the way to go.
