what difference between the Cloud-Init Network Protocol options ?
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?

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. Regards, Liran

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? -----Original Message----- From: Liran Rotenberg <lrotenbe@redhat.com> Sent: Sunday, August 22, 2021 4:01 PM To: Tommy Sway <sz_cuitao@163.com>; Eitan Raviv <eraviv@redhat.com> Cc: users@ovirt.org Subject: Re: [ovirt-users] Re: what difference between the Cloud-Init Network Protocol options ?

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

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?

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?

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.

Yes, it was more about how to do it.
Here are some more detailed links: https://www.ovirt.org/develop/release-management/features/virt/virt-sysprep....
Our linux sealing uses virt-sysprep:

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...

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.

One important thing, you run the virt-sysprep command on the KVM host indicating the VM name to seal, you do not run it inside a VM. It is not like the sysprep command on a Windows machine.
