    runstate: introduce suspended state · ad02b96a
    Luiz Capitulino authored
    QEMU enters in this state when the guest suspends to ram (S3).
    This is important so that HMP users and QMP clients can know that
    the guest is suspended. QMP also has an event for this, but events
    are not reliable and are limited (ie. a client can connect to QEMU
    after the event has been emitted).
    Having a different state for S3 brings a new issue, though. Every
    device that doesn't run when the VM is stopped but wants to run
    when the VM is suspended has to check for RUN_STATE_SUSPENDED
    explicitly. This is the case for the keyboard and mouse devices,
    for example.
