NAME

hv_netvsc - Hyper-V Network Virtual Service Consumer

SYNOPSIS

To compile this driver into the kernel, place the following lines in the system kernel configuration file:

device hyperv

DESCRIPTION

The ifconfig driver implements the virtual network device for Fx guest partitions running on Hyper-V. Fx guest partitions running on Hyper-V do not have direct access to network devices attached to the Hyper-V server. Although a Fx guest can access network devices using Hyper-V's full emulation mode, the performance in this mode tends to be unsatisfactory.

To counter the above issues, the ifconfig driver implements a network Virtual Service Consumer (VSC) that relays network requests from the guest partition to the network Virtual Service Provider (VSP) hosted in the root partition using the high performance data exchange infrastructure provided by hv_vmbus4 driver. The VSP in the root partition then forwards the network related requests to the physical network card.

HISTORY

Support for ifconfig first appeared in Fx 10.0 . The driver was developed through a joint effort between Citrix Incorporated, Microsoft Corporation, and Network Appliance Incorporated.
