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. Approved by: re (gjb)

+.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.

+.Xr hv_netvsc 4 ,
+.Xr hv_storvsc 4 ,
+.Xr hv_ata_pci_disengage 4
+.Sh HISTORY
+Support for Hyper-V in the form of ports was first released in September 2013.
+The daemon was developed through a joint effort between Citrix Inc.,
+Microsoft Corp. and Network Appliance Inc..
+.Sh AUTHORS
+.An -nosplit

+support for \fBhv_kvp_daemon\fP was first added by
