4 HP VRS and VRS-G Software Installation
This chapter provides installation instructions and the basic configuration for HP Virtual Routing
and Switching (VRS) and HP Virtual Routing and Switching Gateway (VRS-G).
Topics in this chapter include:
• VRS and VRS-G Installation Overview
• Preparing the Hypervisor
• Installing the VRS or VRS-G Software
• Configuring and Running VRS or VRS-G
VRS and VRS-G Installation Overview
VRS—The VRS component is a module that serves as a virtual endpoint for network services.
Through VRS, changes in the compute environment are immediately detected, triggering
instantaneous policy-based responses in network connectivity to ensure that application needs
are met.
VRS is an enhanced Open vSwitch (OVS) implementation that constitutes the network
forwarding plane. It encapsulates and de-encapsulates user traffic, enforcing L2-L4 traffic
policies as defined by the VSD. The VRS includes a Virtual Agent (VA) that tracks VM creation,
migration and deletion events in order to dynamically adjust network connectivity.
VRS‐G—The VRS-G component is a software gateway between the HP DCN networks and
legacy VLAN-based networks. It can be installed either on a bare metal server or within a VM.
For optimum performance, bare metal is recommended.

InstallationProcedure—Installation is essentially a three (or four) phase operation:
1.
Preparing the Hypervisor.
2.
Installing the VRS or VRS-G Software: The procedures are slightly different for the two
components and for each supported operating system, therefore each procedure is given
separately.
3. If you need MPLS over GRE:
Installing the VRS Kernel Module for MPLS over GRE.
4. Configuring and Running VRS or VRS-G.
Preparing the Hypervisor
Before installation of VRS/VRS-G, the following requirements must be met for all operating
systems:
