We noticed something weird between two environments. Our full cluster with licensing vs our small cluster for testing (No Subscription).

On the big cluster we can do Snapshots on Windows Server 2022 VM"s in RAW Format for both disk and TPM but on our test server we can't and have to use qcow2 format.

This is the error on the test enviroment under Snapshots.
*** The current guest configuration does not support taking new snapshots ***


We mainly run SQL databases and followed this guide where it states RAW is better.

Cluster is proper datacentre 1U's with onboard RBD storage and test env is NFS network storage.

Any advice/insights?
