Description RHOS Integration 2013-12-12 13:46:11 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/cost-aware-vm-placement-on-host.

Description:

Placement of instances on the host based on the operating systems..
     . Get the os_type from the image when instance is going for provisioning for the first time & create a seperate pool based on the os_type and put the best fit empty selected host into that pool.
     . When another instance request comes for provisioning then it will get the os_type from the instance and scheduler will search the pool based on that os_type to check if any host is available in the pool.
     . If the required os_type pool is found then scheduler picks up one best fit host from that pool & provisions the instance on that host .
     . If required os_type pool is not found then it will create another pool for the os_type taking the next best fit empty host and provisions the instance on that host.
