[libvirt PATCH 5/9] tools: Report hypervisor cpu model names
$ virsh hypervisor-cpu-models --arch x86_64

Note that this includes alias names and cpu models that currently
do not exist in libvirt, e.g. Denverton and Knights Mill.

+**Syntax:**
+
+::
+
+ hypervisor-cpu-models [arch]
+
+List the names of cpu models known to the hypervisor. A hypervisor may define
+alias names for some or all cpu models. Note that the cpu models may differ
+from libvirt, even if named identically.
