_No response_

Bắt đầu với CloudStackImageStoreDriverImpl.java:123 và theo dõi chuỗi lời gọi qua ImageStoreImpl.java:213 và SnapshotManagerImpl.java:604, sử dụng các bước tái hiện và log VMware đã được báo cáo. So sánh đường dẫn trích xuất snapshot với hành vi dành riêng cho VMware. Được xem là hoàn tất khi có thể tải xuống thành công một snapshot volume trong môi trường VMware mà không gặp lỗi trích xuất đã được báo cáo.
