<dd>Configure the HPT (Hash Page Table) of a pSeries guest. Possible
values for the <code>resizing</code> attribute are
<code>enabled</code>, which causes HPT resizing to be enabled if
both the guest and the host support it; <code>disabled</code>, which
causes HPT resizing to be disabled regardless of guest and host
support; and <code>required</code>, which prevents the guest from
starting unless both the guest and the host support HPT resizing. If
the attribute is not defined, the hypervisor default will be used.
