action to see the updated size. Resize to a lower size is supported,

but should be used with extreme caution. Note that this command only

resizes image files, it can not resize block devices like LVM volumes.

submitted against the host device underlying the disk. Once a drive has

been deleted, the QEMU Block layer returns -EIO which results in IO

errors in the guest for applications that are reading/writing to the device.

@item count

can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
|
|
c (char) or i (asm instruction).
|
|
|
|
@item size
|
|
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
|
|
@code{h} or @code{w} can be specified with the @code{i} format to

respectively select 16 or 32 bit code instruction size.
