Open Stack

Hi,

I created two host aggregates, one per host with extra_specs and flavors 
associated as given in [1]. Unfortunately, while the first created 
instance with the desired flavor is launching on the right host, the 
second instance with the same flavor is not spawning on the same host, 
but on another one with a different extra_specs.

My nova.conf scheduling settings are [2], which I assume are correct. 
Any chance to help me understanding what is wrong ?

Thanks,
