Or special case the "cpu 1" command - ie notice that it is being
requested and don't execute 'human-montor-command'. Instead just
record the CPU index, and use that for future "human-monitor-command"
invokations, so we get full compat with the (dubious) stateful HMP
semantics that traditionally existed.
Is 'cpu' (and the followup commands affected by it) the only stateful
HMP command pairing? Is there a way to specify multiple HMP commands in
a single human-monitor-command QMP call?
Indeed, tweaking qemu's human-monitor-command call to track the state
might be cleaner than having libvirt have to tweak API to work around
this wart of HMP.
