Status set_manager(
	Capref	cont,
	Capref	manager,
	Token	cont_id )

Status map_root_page(
	Capref		cont,
	cont_offset	addr )

Status get_root_page(
	Capref		cont,
	cont_offset	*addr )

Status container_fault(
	Token		machine_id,
	Token		cont,
	cont_offset	addr,
	Access		accesss_type )
An access violation has occurred at address addr in container cont_id. 
Status page_discard(
	Token	pageset_id,
	int	no_pages )
The kernel has requested that no_pages has been removed from pageset. 
Status invoke_no_support(
	Token		machine_id,
	Token		cont,
	StateInterval	state_interval,
	invoke params )
An invoke has occured on a remote machine on which their is no local knowledge. 
Status snapshot_request(
	Capref	cont )
Request to kernel to snapshot container. 
Status container_snapshot(
	Token		cont,
	StateInterval	state_interval )
Request to snapshot container cont. 
Status state_interval_stable(
	Capref		cont,
	StateInterval	state_interval )
Manager informs kernel that a stable snapshot has been taken. 
Status state_interval_query(
	Token		cont,
	StateInterval	state_interval,
	SiState		*state )
Does a volitile, stable or recoverable state interval exist? 
Status container_stabilise_request(
	Token		cont,
	StateInterval	state_interval )
This is a request to stabilise a container. 
Status snapshot_discard(
	Capref		cont,
	StateInterval	state_interval )
Manager informs kernel that it has discarded a snapshot (volitile or stable), may not discard most recent recoverable snapshots. 
Status snapshot_is_recoverable(
	Token		cont,
	StateInterval	state_interval )
Kernel informs manager that the referenced snapshot is recoverable. 
Status quality_of_service(
	Capref		cont,

Status cont_rollback(
	Token		cont,
	StateInterval	state_interval )
