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:

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!
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.
