+          Xen: Remove hard-coded scheduler weight
+        </summary>
+        <description>
+          The libxl driver was accidentally hard-coding the per-domain
+          scheduler weight to 1000, silently ignoring any user-provided
+          <code>&lt;shares&gt;</code> in <code>&lt;cputune&gt;</code>. The
+          driver now honors <code>&lt;shares&gt;</code>, and defers setting
+          a default value to Xen. Note that the Xen default is 256, so any
+          domains started after this improvement will have one fourth the
+          shares of previously started domains. If all domains must have
+          equal CPU shares, administrators must manually set the weight of
+          previously started domains to 256, or restart them.
