+          qemu: Better support for international domain names (with wide characters)
+        </summary>
+        <description>
+          There were some issues with multi-byte domains getting lost
+          on daemon restart due to truncation, so the code now handles
+          multi-byte names a bit better.

+          qemu: Support long domain names with namespaces
+        </summary>
+        <description>
+          Domains with extremely long names would fail to start due to
+          temporary namespace paths being created with the whole name.
+          The path is now generated with shortened name instead.
