HYPER-V(4) FreeBSD 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 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(4) driver. The VSP in the root
partition then forwards the network related requests to the physical
network card.
