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.
