HV_KVP_DAEMON(8) FreeBSD 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.
