83submitted against the host device underlying the disk.  Once a drive has
84been deleted, the QEMU Block layer returns -EIO which results in IO
85errors in the guest for applications that are reading/writing to the device.

344@item count
345is the number of items to be dumped.
346
347@item format
348can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
349c (char) or i (asm instruction).
350
351@item size
352can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
353@code{h} or @code{w} can be specified with the @code{i} format to
354respectively select 16 or 32 bit code instruction size.
