A question mark within the device icon, such as , indicates that the type of device cannot
be determined. The device type cannot be determined, for example, when the device has been
removed from the VM Host but not from the virtual machine.
Virtual device type:
• The virtual device type and subset of the hardware path are shown with each virtual device.
This also indicates how the device is being used in the virtual machine.
Backing device:
The storage that backs a virtual device does not necessarily need to be the same type as the virtual
device itself; for example, a file can be the backing storage for virtual disks or virtual DVDs. A file
can be selected as a backing device for one of two purposes:
• The file is intended to represent the capacity of a virtual storage device. This storage space
is treated like a disk drive and can be used the way a disk drive is used (for example, by a
storage manager, or a raw device).
• The file is intended to represent a DVD or CD. In these cases, the file is an .ISO image of the
actual media.
A directory can be a backing device for a virtual DVD. A directory backing device is equivalent
to a physical DVD drive that is empty (the DVD was ejected or has not been inserted). The list of
files in the backing directory are ISO files, each representing a physical DVD that can be inserted
and used as the backing device.
If you eject a file-backed virtual DVD, the storage device is then backed by the directory in which
the ISO file was located. If you insert (select) an ISO file for a directory-backed DVD, the DVD
becomes a file-backed virtual DVD. For information about loading and ejecting a virtual DVD by
command from the virtual machine virtual console, see the HP Integrity Virtual Machines Installation,
Configuration, and Administration manual.
