+ >>> AVAILCPUS

+
+=head3 Description
+
+Returns the number of physical cores in the host that are available to
+the virtualization system (ie. have not been disabled).  See also
+I<PHYSCPUS> which would in almost every case return the same number.

+=head3 Description

+ MEMORY
+

+
+=head3 Description

+
+ MHZ
+
+=head3 Returns

+
+ MODEL
+
+=head3 Returns

+The host CPU model, a string such as C<i686> or C<x86_64>.
+
+=head3 Example
+
+ >>> MODEL
+ <<< 1.0 200 x86_64

+=head3 Description
+
+Returns the host CPU model.

+
+ NODES
+
+=head3 Returns

+The number of NUMA nodes in the host.
+
+=head3 Example
+
+ >>> NODES
+ <<< 1.0 200 1
+
+=head3 Description
+
+Returns the number of NUMA nodes in the host.  If this is 1

+
+ PHYSCPUS
+
+=head3 Returns
+
+The number of physical cores.
+
+=head3 Example

+ <<< 1.0 200 4
+
+=head3 Description
+
+Returns the number of physical cores available on the host.
+
+In some (highly unusual) situations, some cores might be
