Retrieving information from SMBIOS - page 3

Edgar Akhmadeev:

The uuid on my computer matches the hwinfo data exactly. The conversion code is taken from the c++ example.

In hwinfo which one do you have?

I have Wine

But in the /etc/libvirt/qemu/u18.04-MTr.xml file of the host where this VM is spinning:

<domain type='kvm'>
  <name> u18.04-MTr</name>
  <uuid> 1c48eb8c-fd03-4cd4-a3d9-e3133cb57511</uuid>
  <metadata>
    <libosinfo:libosinfo xmlns:libosinfo="http://libosinfo.org/xmlns/libvirt/domain/1.0">
      <libosinfo:os id="http://ubuntu.com/ubuntu/18.04"/>
    </libosinfo:libosinfo>
  </metadata>

Can't find the uuid anywhere

It turns out that in wine SMBIOS does not return an emulated value, but a hardware value. And that's a good thing. Try running hwinfo.

My code took the uuid exactly from the block:

Handle 0x0100, DMI type 1, 27 bytes

which is listed in dmidecode.

System tab from the Motherboard/SMBIOS DMI tree.

How will it work on UPU and Vine?

Somehow didn't think to check there. On VPS it works, uuid is there and again matches the hwinfo data. While there are small errors in the code, fields are creeping away. Will fix it later today. Newbies wait to test for now.

From the command line

From a script

2021.03.23 16:28:41.955 T (EURCAD,H1) UUID: {03000200-0400-0500-0006-000700080009}

Try running hwinfo.

I don't want to drag unnecessary software onto a combat system, especially not a Windows program.

[Vitaly Muzichenko]

All that remains is to remove all unnecessary stuff from the mqh, leaving only the lines for getting the uuid

Ideally, move a few lines into the script itself
