RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.

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.
