HYPER-V(4) Kernel Interfaces Manual HYPER-V(4) 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 hv_netvsc driver implements the virtual network device for FreeBSD guest partitions running on Hyper-V. FreeBSD guest partitions running on Hyper-V do not have direct access to network devices attached to the Hyper- V server. Although a FreeBSD guest can access network devices using Hyper- V's full emulation mode, the performance in this mode tends to be unsatis- factory. To counter the above issues, the hv_netvsc driver implements a network Vir- tual 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_vmbus(4) driver. The VSP in the root partition then forwards the network related requests to the physical network card.

The driver was de- veloped through a joint effort between Citrix Incorporated, Microsoft Cor- poration, and Network Appliance Incorporated. AUTHORS FreeBSD support for hv_netvsc was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>. FreeBSD 15.1 September 10, 2013 HYPER-V(4)
