Hi.

We use cloud-init to boot our hosting servers in an ovirt/RHEV environment. While the integration with a plain CentOS 8 works fine, cloud-init fails with an error on a CentOS 8 machine converted to cloudlinux.

Both the machines are derived from the same base image. Here the output (some informations are redacted for privacy reasons):

Cloud-init is being installed from the standard CentOS 8 repositories without no further customisations. The informations are passed to cloud-init using the Ovirt/RHEV apis in the virtual machine definition, including the various ip addresses.
