XNV™ is a set of software modules for the ExtremeXOS® based switching product portfolio, and is available via the Data Center Feature Pack for Extreme Networks Ridgeline™, a network and service management application. XNV brings insight, control and automation for highly virtualized data centers to the network.

XNV enables the following capabilities:

XNV provides centralized network-based virtual machine (VM) inventory, VM location history and VM provisioning. XNV achieves this through Ridgeline, which interfaces through standard application programming interfaces (APIs) to virtual machine management platforms such as VMware vCenter, Citrix and others.
XNV allows centralized network-based configuration and distributed network-based enforcement of network-level capabilities down to the individual virtual machine level. XNV does this through a virtual port profile (VPP) which can be associated with individual virtual machines in a centralized manner through Ridgeline. VPPs allow configuration of access control lists (ACLs), Quality of service (QoS), rate limiting, and other capabilities to individual virtual machines. VPPs are enforced through the ExtremeXOS enabled network switches running XNV.
XNV provides automated VM lifecycle tracking of virtual machines in the network as VMs migrate from server to server, as well as the ability to automatically move the VM’s VPP to the appropriate network switch and enforce the VPP-based parameters and policies in real time.
