If you're asking about our official test infrastructure for the
OpenStack project, I believe this is infeasible for now. We
currently perform testing within generic virtual machines provided
by HPCloud and Rackspace, so the Nova compute nodes we build and
test are already running under virtualization and in turn manage
only paravirtualized QEMU instances.

In the near term, your best bet is to run your own test
infrastructure supporting the hardware features you require and
report advisory results back on proposed changes:


For a longer term solution, you may want to consult with the TripleO
project with regards to their bare-metal test plan:
