I encountered following issue after trying to backup my VM:
Creating the snapshot failed:



My VM was in read-only mode, so I restarted it (which may be the cause of the problem).
Now, when trying to start my VM, I receive following output:

Hey,

First of all... Have you launched a fsck mannually as mentionned ? x')

If not, you can make it now. The error is directly affected by the "guest mount" done by the host when attempting to save.

And if the save disk directory you will taked for your backup have enough storage, check your filesystem ( if it can take big/large files on)
