Hi,
The link

<https://docs.google.com/document/d/1bAMtkaIFn4ZSMqqsXjs_riXofuRvApa--qo4UTwsmhw/edit> 
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.
Any inputs and comments will be greatly appreciated.
Thanks
Gary
