I have read the document you gave me, but can you list what specific information was deleted by the sealing action? Thanks!

I see. Can I just ask again, I've seen this option when you're referring to sealed Linux, but I don't understand what it means? What is a sealed Linux, and how is it different from a non-sealed Linux? Can you explain, thank you!
Usually you make a template sealed and create multiple VMs from it. The sealing is clearing system specific details. You may find this link handy for sealing: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/htm...

What I want to know is if I use openstack metadata, do I need to configure any additional information related to openstack? For example, do I need to set up an openstack node as an external provider to use cloud-init services based on it?
Not that I am aware of. It's just the protocol cloud-init will read the network information provided. You can set it via API/UI. Or, to set it within the custom script. Bottom line you need: A VM with cloud-init installed, service is running and enabled. Set the configuration you wish to set. If it's a first boot (usually a sealed VM) you can run the VM as you wish. If it's not the first boot, you will need to set the configuration within the Run-Once and run the VM as Run-Once.
I hope it helps to your question, Liran

Adding +Eitan Raviv The general information I can give is that older versions of cloud-init support ENI protocol when network configuration provided while on newer versions (EL7+, Eitan please correct me if I'm wrong), support the openstack protocol. The ENI option was added to support the back compatibility of older OSes and cloud-init versions.

What is the difference between Openstack MateData and ENI in the cloud-init Network Protocol option? Or what kind of scenarios do they apply to?
