HYPER-V(4)

NAME
hv_netvsc - Hyper-V Network Virtual Service Consumer

SYNOPSIS
The hv_netvsc driver implements the virtual network device for FreeBSD guest partitions running on Hyper-V.

DESCRIPTION
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 unsatisfactory. To counter the above issues, the hv_netvsc 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_vmbus driver. The VSP in the root partition then forwards the network related requests to the physical network card.
