The dmidecode tool itself works and shows version 3.3:

~~~
- root@test:~# sudo dmidecode | head
# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 3.1.0 present.
Table at 0x3FFD5000.

Handle 0x0000, DMI type 0, 26 bytes
BIOS Information
        Vendor: Microsoft Corporation
        Version: Hyper-V UEFI Release v4.1
        Release Date: 10/27/2020
~~~

The warning mentions that DMI version 3.3 is too high. With Azure being a prominent player in the Cloud the customer expects that it is handled gracefully without Warnings. The issue occurs on all Azure VMs running RHEL 8.x. On Azure VMs with RHEL7.9 the warning is not visible. The WARNING and location in the source dmiinfo.py:130 the same on RHEL8.4 and RHEL8.6.

~~~

The vMWare or AWS VMs are not having this issue. The problem is visible at Azure that is using a SMBIOS 3.1.0. The problem is that python3-dmidecode ships its own dmidecode shared libary /usr/lib64/python3.6/site-packages/dmidecodemod.cpython-36m-x86_64-linux-gnu.so that is not up-to-date with the latest dmidecode source code shipped also in  dmidecode-3.3-4.el8.x86_64


Version-Release number of selected component (if applicable):
-----------------------------------------------
* dmidecode-3.3-4.el8.x86_64


How reproducible:
-----------------
* Always reproducible

Actual results:
----------------
* The RHSM logs are full with the warnings on DMI decode on Azure VMs running RHEL 8.x


Expected results:
----------------
* No such logs should be logged.
