Switch from QemuOpts to keyval. This enables the introduction of non-scalar machine properties, and JSON syntax in the future.For JSON syntax to be supported right now, we would have to consider what would happen if string-based dictionaries (produced by -M key=val) were to be merged with strongly-typed dictionaries (produced by -M {'key': 123}). The simplest way out is to never enter the situation, and only allow one -M option when JSON syntax is in use. However, we want options such as -smp to become syntactic sugar for -M, and this is a problem; as soon as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}' together with -smp. Therefore, allowing JSON syntax right now for -M would be a forward-compatibility nightmare and it would be impossible anyway to introduce -M incrementally in tools. Instead, support for JSON syntax is delayed until after the main options are converted to QOM compound properties. These include -boot, -acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg. Once JSON syntax is introduced, these options will _also_ be forbidden together with -M '{...}'.

Since this commit QEMU fails to start on my system. ./qemu-system-i386 -machine pc,pcspk-audiodev=audio0 -audiodev pa,id=audio0 qemu-system-i386: Parameter 'audiodev' is missing With best regards, Volker
