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.

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 * 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.
