Good point. This will go away when we merge the guest paging patch. We will still pin 4MB per virtual machine for shadow page tables, but that, too, will go away when we move to a global limit on the number of shadow page tables (say 0.5-1% of total memory, configurable). -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- 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.
