Hardware and system uuid

[Jeff_59]

Hello everybody

I'm still confused concerning the setting/configuration of the uuid parameter.

Indeed, it looks as if VirtualBox allows to set:
----------------------------------------------------------------------------------
1) the system uuid thanks to the command:

VBoxManage setextradata "XP_VM" "VBoxInternal/Devices/pcbios/0/Config/DmiSystemUuid" "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

2) the uuid hardware thanks to the command:

VBoxManage modifyvm "XP_VM" --hardwareuuid "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

3) the machine uuid by editing the .vbox configuration file:

<Machine uuid="{XXXXXXXXXXXXXXX}" name="XP_VM" OSType="WindowsXP">
---------------------------------------------------------------------------------

Moreover the system Uuid i got by running dmidecode on the physical PC does not match the the machine uuid written inside the .vbox configuration file i got from the migration software (P2V). Does that mean that there are several Uuid related to hardware?

If someone could clarify that would be great.

Thanks in advance,

Jeff_59

Hello,

Just wondering: is my question stupid, uninteresting, or does nobody know?

My impression is that nobody knows exactly. There are few discussions about this topic and you can find them using google. There might be an answer but this is not a common use case at all.

It's a kind of detailed implemetation question that can only be answered by looking at the sources. I'm not volunteering to do someone else's homework unless I share their interest in the subject!
