+        </summary>
+        <description>
+          We can't control whether or not QEMU will change its default
+          machine type in the future, or whether downstream distributions
+          will decide to compile out some machine types, so our only option
+          to provide a predictable behavior is taking care of the default
+          ourselves; management applications and users are encouraged to
+          explicitly pick a machine type when creating new guests.

+        <description>
+          Some CPU model names are too long to be stored into the
+          corresponding property, and should be explicitly truncated
+          to avoid unexpected behavior in users of the
+          <code>virNodeGetInfo()</code> API such as

+        <description>
+          Both values were assumed to be smaller than 4096, but in fact
+          they are entirely hardware-dependent and there have been reports
+          of machines presenting much bigger values, preventing libvirt from
+          working correctly; all such limits have now been removed.
