Use this section to configure the embedded Policy Server (ePSX) as a Virtual Machine (VM) application using the vmApplication object.

The core technology of virtualization is the hypervisor. A hypervisor manages virtual machines, allocates resources and provides hardware emulation to the guest systems. A type 1 hypervisor runs directly on the hardware, providing services for all running systems. A type 2 hypervisor runs under a native operating system and provides services to all but the host system. KVM (Kernel-based Virtual Machine) is a type 2 hypervisor for Linux systems and is used to provide SBC virtualization services. The ePSX application executes as a completely independent machine from the hostSBC.

The ePSX shares the host’s network interfaces, but uses a separate internal VM IP address. This is accomplished by linking the physical and virtual interfaces via a Linux bridge device. The bridge is a layer 2 software switch that allows multiple logical interfaces to be combined on the same physical interface. Network processor (NP) enhancements to support multiple virtual interfaces are needed to maintain network performance and security.

SBC 5000 series continues to run ERE by default. The ePSX is installed as an additional package and replaces ERE functionality when running. The ePSX is delivered as an OVF (Open Virtualization Format) package. The OVF is an emerging standard for the distribution of virtual machines. It provides mechanisms for defining the resource requirements of the guest and for tailoring applications to their target environment. The SBC must be first installed with the ePSX option enabled. Once the SBC installation is complete on both servers, then the ePSX OVF package can be installed.

The vmApplication object is only visible when the SBC system is configured for ePSX.
