Description of problem:
After finished installation, the performance profile shown in cockpit is none. But once I click the performance profile button, it changed from none to balanced although cancel the action.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install rhev-hypervisor7-ng-image-update-3.6-20160516.0.el7
2. Login cockpit
3. Click performance profile can cancel the action

Actual results:
1. It changes from none to balanced although the action has been canceled.

Expected results:
1. It should still be none.

Can you check if tuned was started during the course of this bug? Did the system start with tuned not running, and after the bug occurs tuned is running?

Comment 4 Dominik Perpeet 2016-07-06 08:11:50 UTC
Stef, I think this was fixed in https://github.com/cockpit-project/cockpit/pull/4623 - Cockpit 0.112.

Can you please confirm this?

Comment 5 Stef Walter 2016-07-06 10:33:37 UTC
Nope it wasn't. I'm not sure this should be assigned to me. It's either a tuned or a tuned defaults bug.

In order to use DBus to ask tuned what its configuration is, tuned must be started. If started it enables the default tuned performance profile (until the next boot). 

So either tuned behavior must be changed, or the RHEV-H default tuned configuration should be set to disabled so that starting tuned has no effect on the performance profile.

I don't think this should be assigned to me. Reassigning, and changing the component.

Comment 6 Stef Walter 2016-07-06 10:35:14 UTC
Assigning back to the original assignee, Ryan. I think a call needs to be made at a higher level, which of the above fixes are desirable.

It doesn't seem that this is related specifically to Cockpit.

Comment 7 Jaroslav Škarvada 2016-07-08 12:50:08 UTC
Tuned sets default profile during its first start according to the config file where are rules matching default profiles against products/architectures.

We can add rule for your product for Tuned to set it right or it is possible to bypass the autodetection by writing any profile name to:

before Tuned is started. Once this file exists and contains valid profile name, Tuned will not try to autodetect and set the default profile.

Previously we detected the default profile in the spec %post by calling 'tuned-adm recommend', but it turned out it was not the right thing, because the image could be installed on different platform than it is later run at, that's why the default profile is auto detected during the first start. Tuned service is run by default, thus the DBus API should be available and the profile should be already auto-detected. There is DBus method active_profile() which should return the name of currently active profile.

There is also the DBus method recommend_profile() which will return the default profile name as autodetected (i.e. it will run the autodetection and return the profile name, it will not change active profile and it's the same routine that Tuned use during its first start).

In case Tuned is not running and DBus API is not available you can still find out the default profile for your platform by executing 'tuned-adm recommend' (which is again the same routine as Tuned use during its first start but it doesnt' set the profile).

Tuned-adm can also return current active profile (similarly as DBus call active_profile()) but even without DBus available, this can be accomplished by executing 'tuned-adm active'. 

Hope this helps.

I think it should be fixed by:

In Tuned it's fixed in tuned-2.13.0 (RHEL-8.2).
