22This option allows setting an alternate timeout value for RPC calls 

23that have the potential to take a long time. If set, RPC calls to 

24other services will use this value for the timeout (in seconds) 

25instead of the global rpc_response_timeout value.

27Operations with RPC calls that utilize this value: 

28 

29* live migration 

30* scheduling 

31* enabling/disabling a compute service 

32* image pre-caching 

33* snapshot-based / cross-cell resize 

34* resize / cold migration 

35* volume attach
