Next, Intel talks about how they have worked to expose hardware features into OpenStack. This involves work in libvirt as well as OpenStack, so that OpenStack can be aware of CPU functionality (which, in turn, might allow cloud providers to charge extra for “premium images” that offer encryption support in hardware).
