Change BIOS strings of VM

Bjoumlrn Pahl


We have deployed several virtual machines (MS Server 2019 DC). To get the required licenses, all servers (VMs and hosts) are being inventoried; and transferred to a license tool.


As an example: 


MS Windows Server 2019 DC - Licenses available: 100

Hypevisor with at least one Windows Server: 10 

Required licenses: 10 VMs on 10 different Hosts (with 2 Sockets) -> 20


MS Windows Server 2019 DC - Licenses available: 80

... and so on...

The script asks whether the server is virtual or physical. Some of the machines (VMs) return that they are a HPE machine (and therefore physical). 


PS H:\> Get-WmiObject -Class Win32_ComputerSystem
Manufacturer : HPE
Model : ProLiant DL380 Gen10

Actually the query should give this response


PS H:\> Get-WmiObject -Class Win32_ComputerSystem
Manufacturer: Xen
Model: HVM domU



I have found the kb




the behavior is described there.

I guess that the checkbox  (Copy host BIOS settings to VM) was set when the machines was created.

Is there a way to change the entries? Either via CLI on the host, or in the registry (*) (vm)? Or does it need to be recreated (cloned)?


(*) Changes to the registry are reset after a restart
