Masakari shouldn't access Nova DB to check instance's information in any case. For the first implementation, Masakari has to access Nova DB directly since it aims at Juno release, and Nova of the release has some constraints about evacuation of instances. On the other hands, there is no constraint that Masakari hits to in the latest or supported version of Nova for the evacuation.
