Commit id f0a23c0c3 introduced qemuMonitorCreateObjectProps
to manage wrapping the object name and alias; however, calling
virJSONValueObjectCreateVArgs and checking a unary ! return
status meant when the CreateVAArgs function returned zero, then
rather than generating a @propsret, the jump to cleanup would
result in an unexpected failure and cause virsh to issue the
"error: An error occurred, but the cause is unknown" error
message for something like "virsh iothreadadd $DOM 10" (assuming
that IOThread 10 didn't already exist).
