While provisioning certain hosts. the provisioning is failing at the step
of configuring the network.
when I checked the logs, It cannot find the interface with the mac address.
But same provisioning template is working for certain hosts.
We're going to need a lot more information to help you out with this.
For the hosts that work, what are they? Physical or virtual? If
virtual, what platform are you provisioning on? Some require mac
addresses to be provided, some don't.
For those that fail, the same question, but also provide the log of the
failure from /var/log/foreman/production.log on the Foreman host.
