The code path in question should only be used when Nova is setup todo NUMA pinning support, and that is not supported with Xen in OpenStack, only KVM. Did it actually cause failures for you, or are you simply keeping track of all used APIs in Nova as a sanity check ? > Is there a need to use this under Xen?
