I've submitted another blueprint, which is closely bounded with previous one: 

The idea behind those two blueprints is to enable Nova to be aware of host 
status, not only services that run on such. Bringing Pacemaker as a driver for 
servicegroup will provide us with two things: fencing and reliable information 
about host state, therefore we can avoid situations, where some actions will 
misinterpret information like service state with host state.


Kind regards
