NAME

     hv_utils -- Hyper-V Utilities Driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in the system kernel configuration file:

	   device hyperv

DESCRIPTION

     The hv_utils driver provides time keeping, shutdown and heartbeat functionality for FreeBSD guest partitions running on Hyper-V.  Hyper-V is
     a hypervisor-based virtualization technology from Microsoft.  The hv_utils 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:

     (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.

     (b) Integrated shutdown: Guest partitions running FreeBSD can be shut down from Hyper-V Manager console by using the "Shut down" command.

     (c) Heartbeat: This feature allows the virtualization server to detect whether the guest partition is running and responsive.

HISTORY

     Support for hv_utils first appeared in FreeBSD 10.0.  The driver was developed through a joint effort between Citrix Incorporated, Microsoft
     Corporation, and Network Appliance Incorporated.

     FreeBSD support for hv_utils was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>.

HV_KVP_DAEMON(8)					    BSD System Manager's Manual 					  HV_KVP_DAEMON(8)

NAME

     hv_kvp_daemon -- Hyper-V Key Value Pair Daemon

SYNOPSIS

     hv_kvp_daemon [-dn]

DESCRIPTION

     The hv_kvp_daemon daemon provides the ability to store, retrieve, modify and delete Key Value pairs for FreeBSD guest partitions running on
     Hyper-V.

     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 hv_kvp_daemon accepts Key Value pair management requests from the hv_utils(4) 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.

     The options are as follows:

     -d      Run as regular process instead of a daemon for debugging purpose.

     -n      Generate debugging output.

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 Cit-
     rix Inc., Microsoft Corp. and Network Appliance Inc..
