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.

This is not really an error -- see bug 2035662 for its RHEL 9 equivalent.

All we can do in RHEL 8 without backporting the dmidecode rework (bug 2094099), which is not really needed in RHEL 8.
Comment 2 qianzhan 2022-09-06 06:47:00 UTC 
This bug also exists on RHEL-8.7.0-20220830.0 against Satellite6.11/Satellite6.12
Comment 3 qianzhan 2022-11-23 03:03:55 UTC 
This issue happens on RHEL-8.8.0-20221120.2 against Satellite6.12.

Well, it is actually happening, see bug 2173583, so this will be fixed as by-product of fixing that bug.

Also, please note that it has nothing to do with RHEL or Satellite: this comes from the SMBIOS info of the consumer.

Thanks for your update, Pino.

To be a bit more specific: the result of the aforementioned bug is that the mentioned warnings are gone.
Comment 7 qianzhan 2023-03-20 04:12:04 UTC 
The target release of this bug is 8.9.0, so I will verify it when RHEL8.9-CTC1 comes out.
By the way, this bug does not show up when I test RHEL-8.8.0-Beta-1.0 against Satellite6.11/6.12/6.13.

What matters here is the *system* that is registered: is it a real baremetal system, or a VM? What's the hardware (real or virtual) of that system?

Hi, Pino

I do not care about the systems provisioned in beaker by CI when I do testing. So I checked the machines that I used to test RHEL-8.8.0-Beta-1.0:
kvm-01-guest07.lab.eng.rdu2.redhat.com
kvm-01-guest06.lab.eng.rdu2.redhat.com
kvm-06-guest07.hv2.lab.eng.bos.redhat.com

They are KVM virtual machines.
Comment 10 qianzhan 2023-03-20 09:38:55 UTC 
What kind of hardware is needed to verify this bug?
Comment 11 Pino Toscano 2023-03-20 10:14:12 UTC 
The point of this bug is that it entirely depends on the system itself -- it does not even need to be registered, and thus Hosted/Sat/etc does not matter in any way.

The quickest way to check for this problem is:
- install/provision a RHEL 8 system, without even registering it to Hosted/Stage/Sat
- run `subscription-manager facts` to trigger a fact collection
- inspect /var/log/rhsm/rhsm.log for the aforementioned "Error reading system DMI information" warning

(In reply to qianzhan from comment #10)
> What kind of hardware is needed to verify this bug?

Unfortunately I don't know whether there is a way to determine the SMBIOS version of a system without accessing to the system itself; on a system, you can easily check the SMBIOS version using the `dmidecode` command (check at the very top of its output) -- for example:

  # dmidecode | head -n3
  # dmidecode 3.4
  Getting SMBIOS data from sysfs.
  SMBIOS 3.2.0 present.

To reproduce this bug, the "SMBIOS present" line must have a version greater than 2.7.

Thanks for the details, Pino. It's really helpful to verify this bug.
