delphij edc7ea3a5d Import HyperV Key-Value Pair (KVP) driver and daemon code by Microsoft,
many thanks for their continued support of FreeBSD.

While I'm there, also implement a new build knob, WITHOUT_HYPERV to
disable building and installing of the HyperV utilities when necessary.

The HyperV utilities are only built for i386 and amd64 targets.

This is a stable/10 candidate for inclusion with 10.1-RELEASE.

.Sh NAME
.Nm hv_kvp_daemon
.Nd Hyper-V Key Value Pair Daemon
.Sh SYNOPSIS
The \fBhv_kvp_daemon\fP daemon provides the ability to store, retrieve, modify and delete
Key Value pairs for FreeBSD guest partitions running on Hyper-V.
.Sh DESCRIPTION
Hyper-V allows administrators to store custom metadata in the form
of Key Value pairs inside the FreeBSD guest partition. Administrators can
use Windows Powershell scripts to add, read, modify and delete such
Key Value pairs.
The \fBhv_kvp_daemon\fP accepts Key Value pair management requests from the
\fBhv_utils\fP driver and performs the actual metadata management on the file-system.
The same daemon and driver combination is also used to set and get
IP addresses from a FreeBSD guest.
The set functionality is particularly
useful when the FreeBSD guest is assigned a static IP address and is failed
over from one Hyper-V host to another. After failover, Hyper-V uses the set IP
functionality to automatically
update the FreeBSD guest's IP address to its original static value.
On the other hand, the get IP functionality is used to update the guest IP
address in the Hyper-V management console window.
