The oVirt project allows efficient management of virtualized
datacenters. Deciding what machine should host a certain VM is one of
the important functions of the management platform. Unfortunately it
is also one of the complex ones, because there can be many rules
governing the placement policy and there is a time limit in which a VM
has to be started or migration initiated.

All major projects today have a similar scheduling scheme where each VM is
considered separately and that causes fragmentation of free resources.
Both Nova scheduler and Kubernetes provide a set of filter and weight modules.

oVirt has a rich set of modules too but we are now allowing
integration with a next
generation algorithm set based on probabilistic (soft computing) methods thanks
to the Optaplanner project.
