### What to do about it?

_No response_

Bắt đầu bằng cách theo dõi yêu cầu API createSnapshotFromVMSnapshot và đường dẫn VolumeOrchestrator được hiển thị trong management-server.log. Tái hiện lỗi bằng cách sử dụng các phiên bản CloudStack, KVM và host được liệt kê, sau đó xác minh rằng thao tác snapshot hoàn tất thay vì trả về lỗi loại snapshot VM không được hỗ trợ.
