[Bug 1662345] Re: smbios parameter settings not visible in guest

[Louis Bouchard]

Hello,
I have revived this bug and assigned myself to it.

It turns out that -smbios type=1,manufacturer=Scaleway is required by us
to trigger cloud-init's DataSourceScaleway on our infrastructure.

And, moreover, the functionality works as designed on Bionic :

# dmidecode | head
# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.
Table at 0xBC03.

Handle 0x0100, DMI type 1, 27 bytes
System Information
Manufacturer: Scaleway
Product Name: KVM Virtual Machine
Version: 1.0
# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 18.04 LTS
Release:18.04
Codename:   bionic
# arch
aarch64

So I am going to work on trying to identify what was added to version
1:2.11+dfsg-1ubuntu7.4 to make it work as expected.

Clearing outdated bugs atm, lets be honest this is on no-ones prio list at all.
I'll set it to wishlist to reflect that.

The commit Ryan found is in >=2.5 but the issue is seen in Xenial which is 2.5.
Also Dann tested the Yakkety version which seems to have the issue as well.

So there has to be more to it than we know yet.

[dann frazier]

I tested this at Ryan's request, and was using QEMU 1:2.6.1+dfsg-
0ubuntu8 instantiated with the following command line:

sudo qemu-system-aarch64 -enable-kvm -m 4096 -cpu host -smp 8 -M
virt,gic_version=host -nographic -pflash AAVMF_CODE.fd -pflash
AAVMF_VARS.fd -drive if=none,file=disk.img,id=hd0 -device virtio-blk-
device,drive=hd0 -netdev type=tap,id=net0 -device virtio-net-
device,netdev=net0,mac=ac:67:de:d2:4b:06 -drive
file=mini.iso,id=cdrom,if=none,media=cdrom -device virtio-scsi-device
-device scsi-cd,drive=cdrom -smbios type=1,manufacturer="Foobar"

/sys/firmware/dmi is populated, but 'grep -ir Foobar /sys/class/dmi'
returns nothing.

I don't have bandwidth right now to debug, but I can run tests if hw
access is an issue.

I don't have more info;  I had seen emails to qemu-devel from 2015 for
arm64 and smbios parameters

https://lists.nongnu.org/archive/html/qemu-devel/2015-07/msg05404.html

These end up landing in Sep 2015, if I've found them properly:

I also saw that Dannf is subscribed already, are you looking into that?

Hi Ryan,
just to find if that is totally new or maybe bisect - do you have any 
extra data on other "incarnation" of qemu?:
- new Qemu in Yakkety or Zesty-Proposed
- new Qemu in Debian
- Upstream
