+          xen: Add support for 'e820_host' hypervisor feature
+        </summary>
+        <description>
+          <code>e820_host</code> is a Xen-specific option only available for
+          PV guests. When enabled it provides the guest with a virtual e820
+          memory map based on the host one. It must be enabled to allow
+          hotplugging PCI devices to PV guests, particularly when memory
+          ballooning is enabled.
