no i think they mean change the flavor to increase  or decrease the cpu/ram 

this type of virtial vm scaling has been requested in the past but it really non tivial to
implement so we have never approved a spec  to add support to this to nova.

if they are refering to voluem resize that should be possibel live if you are using cinder and not novas
built in rbd support.
