79 * 'O' option string of the form NAME=VALUE,...
80 * parsed according to QemuOptsList given by its name
81 * Example: 'device:O' uses qemu_device_opts.

88 * 'o' octets (aka bytes)
89 * user mode accepts an optional T, t, G, g, M, m, K, k

91 * suffixes T and t, 2^30 for suffixes G and g, 2^20 for
92 * M and m, 2^10 for K and k
94 * user mode accepts an optional ms, us, ns suffix,
95 * which divides the value by 1e3, 1e6, 1e9, respectively
96 * '/' optional gdb-like print format (like "/10x")
98 * '?' optional type (for all types, except '/')
99 * '.' other form of optional type (for 'i' and 'l')
101 * user mode accepts "on" or "off"
