With the NFS, FC, and iSCSI Cinder volume backends, Nova explicitly sets AIO mode ``io=native`` in the Libvirt guest XML. Operators may set this option to True in order to defer AIO mode selection to QEMU if forcing ``io=native`` is not desired.

By default, Nova explicitly sets AIO mode ``io=native`` in the Libvirt

guest XML for NFS, FC, and iSCSI Cinder volumes. Operators may set this

option to ``True`` in order to defer AIO mode selection to QEMU if forcing

``io=native`` is not desired.
