Ok, seems to be I can eliminate the delay by editing the value for the
nova/compute/manager.py related configuration item in nova.conf:

               help='interval to sync power states between '
                    'the database and the hypervisor'),

In the grizzly code there is also this default 600 seconds interval defined
for this check, but still there wasn't this kind of delay present... I
wonder what has changed.

How do you see, is there some negative effects to set the
sync_power_state_interval very low in havana (e.g. 1s or even lower)...?
