Wichtige Einschränkung, deshalb ist Verzicht auf Thin-Pool keine Option!

Allerdings: https://www.computerweekly.com/de/tipp/Die-Snapshot-Grundlagen-von-KVM-verstehen

root@kvmhost1:~# lvcreate -s -n win10test_ss -L 10G kvmhd/win10test
  Logical volume "win10test_ss" created.

TO DO: Wie mit diesem Hilfs-LV Snapshot anlegen?

Ansonsten so sieht es danach aus:
