Description Artyom 2017-06-25 14:32:55 UTC 
Description of problem:
If I set iothreads via UI, I can see that for each iothread created separate virtio-scsi controller with attached iothread, but when I update iothreads via REST I see only one virtio-scsi controller without iothread.

Version-Release number of selected component (if applicable):
rhevm-4.1.3.2-0.1.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. Update VM iothreads via REST
<vm>
<io>
<threads>2</threads>
</io>
</vm>
2.
3.

Actual results:
only one virtio-scsi controller without iothread

Expected results:
two virtio-scsi controllers with attached iothreads
