If the daemon is restarted so we reconnect to monitor, cdrom media

To check for disk status use 'info block' monitor command.
Yuck - this is still polling-based (we have to ask qemu every time we
want to dumpxml). Whatever happened to the proposal of having
interrupt-based cdrom events, where qemu sends an event any time the
virtual tray changes state (whether by monitor command or
guest-initiated), and libvirt monitors those events to update its
internal state at that time, so that libvirt's internal state is always
accurate?
