introduces the concept of a VM ensemble or VM group into Nova.
An ensemble will provide the tenant the ability to group
together VMs that provide a certain service or part of the same
application. More specifically it enables configuring scheduling
policies per group. This will in turn allow for a more robust
and resilient service. Specifically, it will allow a tenant to
deploy a multi-VM application that is designed for VM fault
tolerance in a way that application availability is actually
resilient to physical host failure. </span></font><br>
