the product is no longer active in Red Hat Bugzilla.
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 bug was initially created as a copy of Bug #1904267
I am copying this bug because:
Once we support SMBIOS 3.0, we want it to be enabled automatically when necessary. This can be done in two different ways:
- Automatically enable SMBIOS 3.0 when the tables can't fit in a SMBIOS 2.1 entry point. This keeps gust ABI compatibility and doesn't require a new machine type).
- Enable SMBIOS 3.0 by default on all VMs. This changes guest ABI and can be done only on new machine types.
A VM with more than ~720 VCPUs can hit the 65535 bytes limit on SMBIOS tables. edk2, however, supports SMBIOS 3.0 Entry Points.
We need to support SMBIOS 3.0 entry points on Q35, probably through a new command line option.

Bumping up the stale date.
This BZ is still relevant for the HPE large VM work so we have to keep it open.
It is not urgent because there is a manual workaround, however, it is necessary from a usability perspective.
Igor - feel free to reassign to Julia if necessary. Since it seems bug 2091166 will be resolve, let's get this taken care of too.

Based on Julia's comment, moving this to 9.3, re-setting ITR and bumping up the stale date.

After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
Tested with qemu-kvm-8.1.0-1.el9, the default value was still SMBIOS 2.8. The commit bf376f3020d should not be in it.
Versions:
kernel-5.14.0-362.el9.x86_64
qemu-kvm-8.1.0-1.el9
edk2-ovmf-20230524-3.el9.noarch
1. boot a guest with edk2. (don't add smbios-entry-point-type=64 into qemu command lines), check smbios Entry Point Type in the guest.
2. boot a guest with edk2. (add smbios-entry-point-type=64 into qemu command lines), check smbios Entry Point Type in the guest.
After step 1:
# dmidecode
# dmidecode 3.5
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.
After step 2:
# dmidecode
# dmidecode 3.5
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.
Table at 0x7E9D1000.
Hi Julia,
Could you please help add the DTM? Many Thanks.
