This type of information defines attributes of a system
chassis, such as SMBIOS Chassis Asset Tag.
access inside VM (for example)
Linux: /sys/class/dmi/id/chassis_asset_tag.
Windows: (Get-WmiObject Win32_SystemEnclosure).SMBIOSAssetTag
wirhin Windows PowerShell.
As an example, you could use something like
<chassis>
<entry name='manufacturer'>Huawei</entry>
<entry name='version'>To be filled by O.E.M.</entry>
<entry name='serial'>To be filled by O.E.M.</entry>
<entry name='asset'>To be filled by O.E.M.</entry>
<entry name='sku'>Type3Sku1</entry>
</chassis>
