+++ This bug is a downstream clone. The original bug is: +++ +++ bug 1619474 +++ ====================================================================== Description of problem: The VM is up and the user disables IO Threads and accepts this will be applied on next restart. But on next restart the old setting is still there. Version-Release number of selected component (if applicable): ovirt-engine-4.2.5.3-1.el7.noarch How reproducible: 100% Steps to Reproduce: 1. Power up the VM with IO threads enabled 2. Disable IO Threads, confirm Setting will be applied later (OK) 3. Shutdown the VM 4. Start the VM Note: at item 2, if you click on edit again, the IO Thread setting is checked. Actual results: ovirt-engine-4.2.5.3-1.el7.noarch Expected results: IO Threads Disabled Additional information: The other way around (enabling IO threads) seem to work. It seems to only update Rng(?) and Graphics(?) on shutdown. 2018-08-21 10:40:09,668+10 INFO [org.ovirt.engine.core.bll.ProcessDownVmCommand] (EE-ManagedThreadFactory-engine-Thread-1632) [6e6432c9] Running command: ProcessDownVmCommand internal: true. 2018-08-21 10:40:09,893+10 INFO [org.ovirt.engine.core.bll.UpdateVmCommand] (EE-ManagedThreadFactory-engine-Thread-1632) [53f4758c] Running command: UpdateVmCommand internal: true.

(In reply to Michal Skrivanek from comment #1) > Sharon? This is a regression in 4.2.5 due to patch [1] which enabled IO threads as default for Server VM type. The reason is that in case IO threads is disabled, it is not written/read by OvfReader.java and vmBase default value is used. Up till 4.2.5 the default value was 0 and in mentioned patch [1] it was changed to 1. [1] https://gerrit.ovirt.org/#/c/92776/ (Originally by Sharon Gratch)
Verified on: ovirt-engine-4.2.6.4-0.0.master.20180823141941.gitb3a5b18.el7.noarch Steps of verification: 1. Create a new VM with IO-Threads enabled. 2. Start the VM. 3. Disable IO-Threads (confirm that the change require VM restart). 4. Restart the VM. 5. Check the VM IO-Threads. Results: The VM IO-Threads was changed and disabled. (Originally by Liran Rotenberg)
