Thanks for confirmation.So I think the manual has to be updated.Let me know if you want me to open a documentation bug or not.yes, please open a bug on that.
Have you any suggestion on how to set from the REST API, so that I can make some tests?Sure, for setting IO threads number via REST API, you should run the following request:PUT http://engine:port/ovirt-engine/api/vms/vm-id # request body:
<vm>
<io>
<threads>2</threads>
</io>
</vm>
