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.

   System Status Details
+-------------------------------------------+
Overall Status: Invalid

Awesome OS Server Basic (data center):
- Only supports 2GB of 4GB of RAM.

UNABLE_TO_GET_NAME:
- Guest has not been reported on any host and is using a temporary unmapped guest subscription.

Awesome OS Server Bits:
- Not supported by a valid subscription.




NOTICE: Both the Traceback and the "UNABLE_TO_GET_NAME" results are unexpected.
Comment 4 John Sefler 2015-03-30 20:33:39 UTC 
Although this is a regression, it is not a blocker for rhel6.7 since it happens rarely.  If it does occur, the user should re-try.
Comment 5 Adrian Likins 2015-04-07 20:14:03 UTC 
If compliance status includes reasons that do not include a prod id, this
could get triggered. unmapped guest related? It's similar to 
https://bugzilla.redhat.com/show_bug.cgi?id=1201727

Looks like this got broken in:

commit 3d5a9a5dba480d75f52ff7201af01496c871ab58
Author: Adrian Likins <alikins>
Date:   Mon Jan 19 13:16:12 2015 -0500

    1183122: Fix KeyErrors building dbus ent status
    
    If the info returned from a cert_sorter.get_compliance_status
    didn't have keys we expected, we broke.
    
    Attempt to be more lenient about the structure of compliance
    status. Ignore missing keys, empty lists, etc.
    
    Move refresh_compliance_status to managerlib, and add tests
    to test_managerlib.



I'm not going to say it's DBUS.

But it's DBUS.

(more accurately, the cockpit related changes we backed out for 7.1).
Comment 7 Devan Goodwin 2015-04-09 19:33:39 UTC 
We believe this will be fixed by reverting the dbus code that triggers events on compliance status changes.

subscription-manager.git: cf23450fc1d519a7d0e90611499047ce2e7c3334
Will appear in subscription-manager-1.15.3-1
Comment 8 John Sefler 2015-04-20 16:24:06 UTC 
Since I don't have an exact reproducer, I'm going to let this one bake for a little while.  If it does not re-surface through automated test runs, then I'll move it to VERIFIED.
