A VBD is a software object that connects a VM to the VDI, which represents the contents of the virtual disk. The VBD has the attributes which tie the VDI to the VM (is it bootable, its read/write metrics, and so on), while the VDI has the information on the physical attributes of the virtual disk (which type of SR, whether the disk is shareable, whether the media is read/write or read only, and so on). The VBD objects can be listed with the standard object listing command (xe vbd-list), and the parameters manipulated with the standard parameter commands. See Section 5.3.2, "Low-level param commands" for details. 80
