The support for the 'sgio' attribute for SCSI-backed devices was dropped as there wasn't really ever any upstream support for it. The docs do state that support for this depends on the hypervisor itself, but we can be more clear that there is no hypervisor which does support it. There is also a suggestion to use 'sgio' instead of 'rawio' as being more "secure" but since it no longer works drop this suggestion.
