Removed docker references (the driver has been removed from nova). Update confilcting pages including tables to use xrefs instead. Add a rpc_all section to handle conflicts in the training-guides. Closes-Bug: #1291138 Closes-Bug: #1292612 Change-Id: I67ad31c3913cae4c2e9e3d2ce41302717af5d839

<para>It is possible to use Hyper-V as a compute node within an OpenStack Deployment. The

<systemitem class="service">nova-compute</systemitem> service runs as "openstack-compute," a 32-bit service directly upon the Windows

platform with the Hyper-V role enabled. The necessary Python components as well as the

<systemitem class="service">nova-compute</systemitem> service are installed directly onto the Windows platform. Windows Clustering

Services are not needed for functionality within the OpenStack infrastructure. The use of

the Windows Server 2012 platform is recommend for the best experience and is the platform

for active development. The following Windows platforms have been tested as compute nodes:<itemizedlist>
