Stephen Finucane 564f5330c3 [config-ref]: update nova config options for stable/ocata 
This significant rework occurs due to recent changes in the
openstack-doc-tools project.

There are some manual fixes to the following options, where invalid rST
was included. These have been fixed on nova master but still need to be
backported to stable/ocata. This will be done separately.

- block_device_allocate_retries_interval (DEFAULT)
- torrent_images (xenserver)

Hypervisor configuration basics

The node where the nova-compute service is installed and operates on the same node that runs all of the virtual machines. This is referred to as the compute node in this guide.

By default, the selected hypervisor is KVM. To change to another hypervisor, change the virt_type option in the [libvirt] section of nova.conf and restart the nova-compute service.

Here are the general nova.conf options that are used to configure the compute node's hypervisor: nova-DEFAULT

Specific options for particular hypervisors can be found in the following sections.
