Logical Domain Servers

Overview

 Logical Domains (LDOM) provide virtual machines on SPARC platforms that have hypervisor support. A Logical Domain has its own operating system (guest OS) and identity within a single computer system. Depending on the system resources provided via the hypervisor, Logical Domains can appear to the user (or application) as a full physical machine. Crossbow provides the virtual network support for LDOMs. More information on LDOMs is located at the Logical Domains Community site.
 LDOMs can be reserved under the Test Farm Virtual Machines interface. After making a reservation an email will be sent providing the login information.
