Renaming ethernet adapters to ethX

Infrastructure

In the Morpheus documentation (see Creating a Morpheus VMware Image — Morpheus Docs documentation (morpheusdata.com) it recommends disabling “consistent device naming” and manually renaming adapters so they appear as eth0. However this is not recommended by RedHat, on this page they state a server where it has been done will NOT be supported. Chapter 1. Consistent network interface device naming Red Hat Enterprise Linux 8 | Red Hat Customer Portal. What exactly is the problem with leaving consistent device naming enabled? thanks Mike

The cloud-init that Morpheus uses to configure provisioned VMs seems to add an alias to the first network interface as determined by cloud-init. I don’t believe consistent network device naming needs to be disabled. In the system images, net.ifnames=0 is not set as a boot parameter. Those names are still on the provisioned VMs.

Hello Nick,

Thanks for confirming my thoughts, been running with consistent network device naming for a good number of weeks without issue.

Hi, Nick.
Where can I find details on how Morpheus is creating and alias for the first NIC?

I am setting up a VM from Ubuntu published Cloud-init image and I have to disable consistent network device naming in order to get VM on the network with static IP.

Thanks
