The quotes were introduced for C code (and especially qtest), not for the shell. We have something like response = qmp("{ 'execute': 'qom-get', 'arguments': { 'path': %s, " "'property': 'temperature' } }", id); These are sent to QEMU as double-quoted strings (the single-quoted JSON is parsed to get interpolation and printed back; commit 563890c7c7, "libqtest: escape strings in QMP commands, fix leak", 2014-07-01). However, doing the interpolation requires a parser that recognizes the single-quoted strings.
