+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ * Index Key Name
+ * 0 FullyQualifiedDomainName
+ * 1 IntegrationServicesVersion
+ * 2 NetworkAddressIPv4
+ * 3 NetworkAddressIPv6
+ * 4 OSBuildNumber
+ * 5 OSName
+ * 6 OSMajorVersion
+ * 7 OSMinorVersion
+ * 8 OSVersion
+ * 9 ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.
