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. -.Sh SEE ALSO -.Xr hv_vmbus 4 , -.Xr hv_utils 4 , -.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 -.Fx -support for \fBhv_kvp_daemon\fP was first added by -.An Microsoft BSD Integration Services Team Aq bsdic@microsoft.com . diff --git a/contrib/hyperv/tools/hv_kvp_daemon.c b/contrib/hyperv/tools/hv_kvp_daemon.c deleted file mode 100644 index 890ca5b551e1..000000000000 --- a/contrib/hyperv/tools/hv_kvp_daemon.c +++ /dev/null @@ -1,1518 +0,0 @@ -/*- - * Copyright (c) 2014 Microsoft Corp. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
