-.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_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
-.Fx
-support for \fBhv_kvp_daemon\fP was first added by
-.An Microsoft BSD Integration Services Team Aq bsdic@microsoft.com .
