<p>The first block (in red) indicates the host hardware capabilities, currently
it is limited to the CPU properties and the power management features of
the host platform, but other information may be available, it shows the CPU architecture,
topology, model name, and additional features which are not included in the model but the
CPU provides them. Features of the chip are shown within the feature block (the block is
similar to what you will find in a Xen fully virtualized domain description). Further,
the power management features supported by the host are shown, such as Suspend-to-RAM (S3)
and Suspend-to-Disk (S4). In case the query for power management features succeeded but the
host does not support any such feature, then an empty <power_management/>
tag will be shown. Otherwise, if the query itself failed, no such tag will
be displayed (i.e., there will not be any power_management block or empty tag in the XML).</p>
<p>The second block (in blue) indicates the paravirtualization support of the
Xen support, you will see the os_type of xen to indicate a paravirtual
kernel, then architecture information and potential features.</p>
<p>The third block (in green) gives similar information but when running a
32 bit OS fully virtualized with Xen using the hvm support.</p>
<p>This section is likely to be updated and augmented in the future, see <ahref="https://www.redhat.com/archives/libvir-list/2007-March/msg00215.html">the
