This should be a pretty easy questions to answer. After all is well , and your Windows images are sealed, sysprep'ed and Cloudbase-init has installed and shut down the guest, how do you re-arm Cloudbase-init if you have to power the box back online ? I know I have to re-sysprep the box , but do I need to uninstall , reboot , install Cloudbase-init again ? or is there an easy command line option I can do to re-run properly after a power up?

Thx

To replicate what is done by the installer to re-sysprep is the best commandline

sysprep.exe /generalize /oobe /shutdown /unattend:C:\progra~1\cloudb~1\cloudb~1\conf\Unattend.xml

Yes, it's very easy, just delete the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Cloudbase Solutions\Cloudbase-Init

Or, if running an x86 version on x64:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Cloudbase Solutions\Cloudbase-Init

Please note that configurations are specific to each instance id, this means that if you snapshot an image in OpenStack and boot from the snapshot, it's not necessary to delete the key.

I seem to be missing something in my reseal recipe. Thus far I have found it more effective to uninstall and reinstall and use init MSI GUI to call sysprep. Any recommendations on calls I might need to do after re-opening a template? Del key, run sysprep using the cb unattend?
