Not sure if there is a business case to be made here.  If this is 
requested, I would like to understand the rationale behind it?  Does 
the customer think that because the hypervisor is VMware based that 
they will get HA and vMotion-like benefits with OpenStack?  Are they 
erroneously mixing and matching cloud types (enterprise virtualization
vs. an elastic cloud)?

As a proof of concept, maybe.  As production infrastructure, probably not
for many reasons.

My guess is that it's a philosophical misunderstanding of the nature of
the two cloud types: one designed for virtualization, static/legacy
workloads, etc (VMware) and one designed for new elastic applications 
where the apps *expect* the infrastructure to fail (OpenStack).
