Finally, I modify configdrive.py to dismount CDROM:

C:\Program Files\Cloudbase Solutions\Cloudbase-Init\Python\Lib\site-packages\cloudbaseinit\metadata\services\configdrive.py

import os import shutil +import ctypes ... def cleanup(self): LOG.debug('Deleting metadata folder: %r', self.mgr.targetpath) shutil.rmtree(self.mgr.targetpath, ignoreerrors=True) self.metadatapath = None + driveletter = os.popen('wmic logicaldisk where VolumeName="config-2" get Caption | findstr /I ":"').read() + if driveletter: + LOG.debug('Eject metadata drive: %s', str(driveletter).rstrip()) + ctypes.windll.WINMM.mciSendStringW(u"open " + str(driveletter).rstrip() + " type cdaudio alias ddrive", None, 0, None) + ctypes.windll.WINMM.mciSendStringW(u"set d_drive door open", None, 0, None)

Finally, I modify configdrive.py to dismount CDROM:

        def cleanup(self):
            LOG.debug('Deleting metadata folder: %r', self.mgr.targetpath)

Finally, I modify configdrive.py to dismount CDROM:CDROM, and tested in windows 2016 Std server:

 ... ...
        def cleanup(self):

            shutil.rmtree(self._mgr.target_path, ignore_errors=True)
            self._metadata_path = None
    +       drive_letter = os.popen('wmic logicaldisk where VolumeName="config-2" get Caption | findstr /I ":"').read()
    +       if drive_letter:

    +           ctypes.windll.WINMM.mciSendStringW(u"set d_drive door open", None, 0, None)

Finally, I modify configdrive.py to dismount CDROM, and tested in windows 2016 Std server:server.

Update: just tested windows 2012 R2, also work.
