-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I recovered from this error by import my base-image in a new machine and make a restore of the backups. But is it possible "by hand" to merge latest snapshot in to a base-image to get a new VM up and running with the old disk image?

I have tried with qemu-img but have no go with it.
