Yes, looks like it. It would be possible to have libxl retry
automatically since Linux eject and unlock the cd-rom tray, then QEMU
does send an event via QMP about this, so libxl could retry after
receiving the event. Waiting for events is just not implemented in
libxl, but that something that could be done.

The event is, for example:
    'event': 'DEVICE_TRAY_MOVED', 'data': {'device': 'ide-5632', 'tray-open': 
True, 'id': 'ide-5632'}

Cheers,
