How to set a serial number for a guest VM

[Zebberdee70]

Hello,

I would like to use a guest VM with Microsoft Intune for testing.
But in order to do this I need to import the VM into Intune and the VM must have a serial number.
I have looked on many forums and the only info I could find was a post where it was said to enter "UUID != serial" in Options/SMBios
When I tried that it literally set the serial number to that string.

My VM is running OVMF
And PROXMOX 7.1-11

Could someone please help with some advice on how I could set a serial number for a guest VM ?

Thanks in advance

The SMBIOS settings (type 1) under VM Options has a field for Serial (apart from UUID). Is that not what you are looking for?

Hi Leesteken,
Thanks for your reply.
That is the field I have been using.
if I enter a string such as SMC1026 in the serial field then fire up the VM.
when I query WMI ( Windows 10) the serial number field is empty.
however when I entered UUID=SMC1026 in the SMBIOS serial field,
I could see that exact string with a WMI query on the VM.

I'm not familiar with WMI,but when I set the Serial field to SMC1026 and use wmic bios get serialnumer in a Windows 10 VM it show thiss:
SerialNumber SMC1026
It looks like smbios1: serial=U01DMTAyNg==,base64=1 In the VM configuration file.
Am I doing it wrong or did I misunderstand your explanation?

I don’t believe this
I just entered a new value into the SMBIOS serial field,
shutdown, and started the VM when I checked WMI-BIOS-Serial the new value is there
I swear I did that many times a few days ago !!!

Big thanks Leesteken
