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.
