Fixed In Version:	ovirt-node-2.5.0-11.el6	Doc Type:	Bug Fix
Doc Text:	When loading the Red Hat Network (RHN) screen the Red Hat Enterprise Virtualization Hypervisor previously used the rhn_check command to determine whether the machine was registered to RHN. This led to delays on systems with slow network connections. As a result the screen appeared to flicker when loading the RHN configuration screen. The hypervisor now checks the local file system to determine whether the system is registered to RHN, eliminating the delay.	Story Points:	---

I think we should be consistent and show it on all translations.

Comment 17 Fabian Deutsch 2012-11-12 14:25:55 UTC

Okay. The following patch enables the loading message for all transitions:

I have verified the fix and able to see "loading" whenever we move from one page to other. 
But from user experience point of view older implementation was much better. The issue was seen mostly when we use to navigate to & from network options. Now we see the message "loading" for all the options which is causing a while navigation for all the operations.

Comment 29 Fabian Deutsch 2012-12-10 09:21:28 UTC

The check is now file-based  which makes the page-loading significantly faster.

http://gerrit.ovirt.org/#/c/9754/

Tested as follows:

1. Install with applied patch
2. Register to satellite server
3. Switch between pages is fast and /etc/sysconfig/rhn/systemid exists

I've added a minimum display time of 300ms to the "loading message" to give the user an idea of what the text says.
We can remove this delay but then a short display time can be seen as flickering and raise the feeling of missing something (the text appears but can not be read fast enough to understand what it says).

Will this patch gone get included in RHEL6.4 Hypervisor? If yes then please let us know which release?

Comment 33 Mike Burns 2012-12-11 14:32:15 UTC

Yes, it will be included in 6.4 RHEV-H.  It will should be included in one of the beta refreshes, but it's unclear at the moment which one.

Comment 38 Ashish 2013-02-01 05:58:50 UTC

Verified with RHEL6.4-S4-Hypervisor (rhevh-6.4-20130116.3.0).
Works fine. Can see the loading message.
