  67  * Supported types:

  69  * 'F'          filename
  70  * 'B'          block device name
  71  * 's'          string (accept optional quote)
  72  * 'O'          option string of the form NAME=VALUE,...
  73  *              parsed according to QemuOptsList given by its name
  74  *              Example: 'device:O' uses qemu_device_opts.
  75  *              Restriction: only lists with empty desc are supported
  76  *              TODO lift the restriction
  77  * 'i'          32 bit integer
  78  * 'l'          target long (32 or 64 bit)
  79  * 'M'          just like 'l', except in user mode the value is
  80  *              multiplied by 2^20 (think Mebibyte)
  81  * 'f'          double
  82  *              user mode accepts an optional G, g, M, m, K, k suffix,
  83  *              which multiplies the value by 2^30 for suffixes G and
  84  *              g, 2^20 for M and m, 2^10 for K and k
  85  * 'T'          double
  86  *              user mode accepts an optional ms, us, ns suffix,
  87  *              which divides the value by 1e3, 1e6, 1e9, respectively
  88  * '/'          optional gdb-like print format (like "/10x")
  89  *
  90  * '?'          optional type (for all types, except '/')
  91  * '.'          other form of optional type (for 'i' and 'l')
  92  * 'b'          boolean
  93  *              user mode accepts "on" or "off"
  94  * '-'          optional parameter (eg. '-f')
