.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines in
|

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides time keeping, shutdown and heartbeat
|
|
functionality for
|
|
.Fx
|
|
guest partitions running on Hyper-V.
|
|
Hyper-V is a hypervisor-based virtualization technology from Microsoft.
|
|
The
|
|
.Nm
|
|
driver is one of the core drivers required to be present in guest
|
|
partitions running on Hyper-V.
|
|
This driver provides the following
|
|
functionalities to guest partitions:
|
|
.Pp
|
|
(a) Time Keeping: The clock inside the guest partition will remain accurate by
|
|
synchronizing to the clock on the virtualization server via Timesync service,
|
|
and with the help of the pluggable time source device.
|
|
.Pp
|
|
(b) Integrated shutdown: Guest partitions running
|
|
.Fx
|
|
can be shut down from
|
|
Hyper-V Manager console by using the
|
|
.Qq Shut down
|
|
command.
|
|
.Pp
|
|
(c) Heartbeat: This feature allows the virtualization server to detect whether
|
|
the guest partition is running and responsive.
