File backed memory is enabled per Nova compute host. When enabled, host
will report 'file_backed_memory_capacity' for available memory.
When enabled, instances will create memory backing files in the
directory specified in libvirt's qemu.conf file 'memory_backing_dir'
config option.
This feature is not compatible with memory overcommit, and requires
'ram_allocation_ratio' to be set to 1.0

Now that Queens supports attaching virtual GPUs to an instance, we need to
properly document which hypervisors support that, how to use that feature and
what the existing caveats are.
