If i have well understand the placement solution provided by Openstak, yhe VM placement consists to randomly assign a VM to an available host.

Thus, i would like to know how the different measures or performances (RAM, CPU, Storage, etc) of each server in an infrastructure are monitored and taken into account to place correctely the arrived VMs in the right server ?

@Marc if you're the one that asked the original question, please consider updating the question instead of adding details in the comments: this makes things more readable.

Ok , thanks a lot. To be more precisely on my question, i would like to know how the RAM performance is monitored to the placement solution ? And, why the openstack placement solution is not proceeding as it does by Best first decreasing, or first fit increasing methods ? Thanks for your answers.
