Novell supports three OES services running on a Xen VM host server: Novell Linux User Management, Novell Storage Management Services, and Novell Cluster Services.
Having these components installed on a Xen VM host server provides the following benefits:
Linux User Management (LUM): Lets you SSH into the server for management purposes by using an eDirectory user account.
This functionality requires that you
Enable SSH communications through any firewalls that are running on the server
Configure LUM to allow SSH as a LUM-enabled service. For more information see
Storage Management Services (SMS): Lets you back up the VM host server and all of the VM guests.
Novell Cluster Services (NCS): Lets you cluster the VM guests running on the VM host.
