1. A computing electronic complex (CEC) comprising: a processor; one or more physical input/output (I/O) adapters that support I/O communication with an external network; and a memory coupled to the one or more processors, wherein the memory includes: a virtualization management component that supports creation of and communication between one or more virtualized operating system (OS) partitions; at least one operating system (OS) partition, including a first virtual input/output (I/O) server (VIOS) having a cluster-aware (CA) OS that executes on a virtual processor resource of the VIOS to perform the function of: registering the first VIOS with a VIOS cluster comprising at least a second VIOS, wherein the registering of the first VIOS to the VIOS cluster enables the first VIOS to receive cluster specific data to make the first VIOS aware of the VIOS cluster, wherein the first VIOS is able to communicate information with other VIOSes within the VIOS cluster.
