→An Overview of Hyper-V Integration Services
* '''Hyper-V Key/Value Pair Exchange''' - Provides the ability for the child and parent partitions to exchange configuration information through pre-defined registry entries. In the case of the parent partition, it is able to view, set and delete registry entries in the child partition's guest operating system. In addition, the parent partition configures a number of registry entries into the guest's registry which provide information about the parent.
== Understanding Hyper-V Key/Value Pair Exchange == The Key/value pair exchange entries provided by the Hyper-V Key/Value Pair Exchange component of the Hyper-V Integration Services are stored in on the following guest operating system in the following registry locations:
* HKEY_LOCAL_MACHINE\Software\Microsoft\Virtual Machine\Auto
* HKEY_LOCAL_MACHINE\Software\Microsoft\Virtual Machine\Guest\Parameters
Registry entries in relating to the configuration of the child partition 's guest operating system are located in HKEY_LOCAL_MACHINE\Software\Microsoft\Virtual Machine\Auto and are accessible to the parent partition. The specific registry entries are outlined in the following table:
<table border="1" cellpadding="5" cellspacing="0" id="E3B" style="border-collapse: collapse; border-color:#cccccc; border-style: solid; border-width: 1px; margin-bottom:20px">
In addition, the parent partition inserts the following information about itself into the HKEY_LOCAL_MACHINE\Software\Microsoft\Virtual Machine\Guest\Parameters of the guest operating systemallowing the guest to obtain useful information about the host environment on which it is running:
