.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.
