+          qemu: Remove support for virDomainQemuAttach and virConnectDomainXMLFromNative APIs
+        </summary>
+        <description>
+          The qemu implementations for the APIs mentioned above were removed
+          and the APIs now return error. The implementation was stale for a
+          long time and did not allow working with moder use of qemu in libvirt.
