GitHub user daviftorres added a comment to the discussion: What does Snapshots, Backups, and Incremental Snapshots mean in CloudStack
> You can most certainly create instance snapshots while the instance is in a > shutdown state. You can also create instance snapshot without memory. Dear @chunkyen , than you for your reply. What you said is generally correct, but in practice it is not always true. There are cases where creating a snapshot without memory is not allowed, and the UI error message does not clearly explain why. For example, in the instance below, snapshot creation only works if **Snapshot memory** is enabled: <img width="1582" height="785" alt="image" src="https://github.com/user-attachments/assets/1bb61eab-60d6-4356-9da8-7f0ea1cdcc2a"; /> However, on other instances, snapshot creation works fine without memory, for example: <img width="1582" height="371" alt="image" src="https://github.com/user-attachments/assets/e699c0b3-df65-4b1f-978b-541dc1a0caca"; /> Some additional context: The instance that only allows snapshots with memory has `qemu-guest-agent` installed and was deployed from an ISO. The instance that allows snapshots without memory was deployed from an out-of-the-box template and does not have `qemu-guest-agent` installed. So while snapshots without memory are supported in general, there seems to be some internal logic or constraint that blocks it in certain cases, and the current error message does not make this clear. Do you know what specifically causes this behavior?
