I think we need to freeze the hypercall API at some time, and consider it a stable kernel external API. We do then need to document these calls, and non-GPL hypervisors can implement it. We could eventually have a similar situation with one of the other non-GPL hypervisors on s390 that run Linux. so long, Carsten ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
