100Remove host block device.  The result is that guest generated IO is no longer
101submitted against the host device underlying the disk.  Once a drive has
102been deleted, the QEMU Block layer returns -EIO which results in IO
103errors in the guest for applications that are reading/writing to the device.

358
359@table @var
360@item count
361is the number of items to be dumped.
362
363@item format
364can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
365c (char) or i (asm instruction).
366
367@item size
368can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
369@code{h} or @code{w} can be specified with the @code{i} format to
370respectively select 16 or 32 bit code instruction size.
