1.2 Preparing the Server When Multiple NICs and DNS Addresses Exist

If your anticipated Cloud Manager Orchestration Server has multiple network interfaces and multiple DNS addresses, you need to edit the /etc/hosts file on the server to change the default ( or address to the actual IP address of the server. This is necessary because at server startup, the Orchestration Server tries to determine the matrix.hostname.full fact. If the IP address of the hostname is found to be a loopback address (for example,, it is skipped and subsequently configured incorrectly.

If this change is not made, the Install Agent action performed on a VM misconfigures the VM to point to the wrong address (because the grid’s matrix.hostname.full fact is incorrect), resulting in no connection to the server.
