The command "qemu-img map ${image_name_img}" is used to display the mapping information for a disk image in QEMU (Quick Emulator) format.
Here's a breakdown of the command:
- "qemu-img" is the command-line tool in QEMU used for creating, converting, and managing disk images.
- "map" is a subcommand of "qemu-img" that allows you to display the mapping information.
- "${image_name-img}" is a placeholder indicating the name or path of the disk image file you want to inspect. You need to replace it with the actual name or path of your image file.
When you run this command, QEMU will read the specified disk image and display the mapping information, which includes the list of extents and offsets of the image file. This information helps you understand how the data is stored within the image file and how it maps to the virtual machine's storage.
