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 con‐ figuration file: device hyperv

DESCRIPTION

The hv_netvsc driver implements the virtual network device for FreeBSD guest partitions run‐ ning 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 unsat‐ isfactory. To counter the above issues, the hv_netvsc driver implements a network Virtual Service Con‐ sumer (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.
