If so, can I still run it on KVM Server fn the oVirt platform? It seems that a lot of oVirt's configuration information is not stored in QUEMU's configuration file like ordinary KVM SERVER, but in the database.

Thank you very much!
However, if you use virt-Sysprep, you need to use this tool to complete template creation inside the VM to be created. Using oVirt's own template encapsulation option, however, does not require you to log in to the VM to run similar commands. It's just that using the Virt-Sysprep tool gives you more autonomy and options to choose from, whereas oVirt's own template encapsulation options are fixed and you can't personalize more options.
Am I getting that right?
Yes, ovirt manages your environment and such does for you some of the operations to ease you from doing it manually. When you create a template in ovirt you may or may not set the sealing option. In the bottom line it will run virt-sysprep with the parameters we thought are right. Note the documentation in the thread, for windows OS you will need to do it manually.

Usually you make a template sealed and create multiple VMs from it. The sealing is clearing system specific details.

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.

Once the KVM host is part of an oVirt cluster, many interactions come from the VDSM service. It would help if you used a different KVM host for this kind of procedure.
