The problematic values that qemu outputs are, at least to my knowledge, only in the some of the messages in the QMP communication, which we do not do. We parse JSON from: - output of ldmtool - output of qemu-img - QMP schema - SimpleStream files Furthermore, why not just fix qemu, instead of letting its "JSON implementation" rule out perfectly compliant JSON parsers? -- Pino Toscano
