- * 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.

- * The KVP opcodes are defined by the host and it was unfortunate

- * KVP operations defined by the host.
- * Here is the level of compatibility
- * (between the user level daemon and the kernel KVP driver) that we

- *
- * An older daemon will always be supported on a newer driver.
- * A given user level daemon will require a minimal version of the
