Please update the docs - remove section with io threads editing. It has been removed in 4.2 +++ This bug was initially created as a clone of Bug #1592990 +++ [...] --- Additional comment from Gianluca Cecchi on 2018-06-20 13:36:18 CEST --- To be noted that as it is now (not possible to specify inside the GUI the number of I/O threads), in my opinion the documentation is a bit misleading here: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/virtual_machine_management_guide/editing_io_threads Reading the guide, it gave me the idea that it is possible to change the number, even if the default and recommended (upon which kinds of tested scenarios?) one is to leave the value of "1"
