Hi,

Cloud-init is usually used only once to initialize the guest OS configuration.

When using the normal Run, if it's the first time this VM goes up, the cloud-init will be included, otherwise it won't as it isn't supposed to be re-configured or being configured after the VM already ran.

However, Run-Once bypasses this safety check and allows it, making the VM as a "fresh one".

I hope it clears things up a bit.

Liran.

Hi Users,

I am new to oVirt and having some confusion with cloud-init.
I have a VM which supports Cloud Init and when I enable Cloud Init under Initial boot settings of VM, the cloud-init config disk isn't attached to the VM.
If I use Run-Once and enable Cloud-Init the config disk is attached to the VM and works as expected.

Is cloud-init only supposed to work with Run-Once or am I missing something?

Thanks in advance.
Shantur
