New hardware ID

Question

Hi all,

Is there a reason why my hardware ID for my VM would reset each day? It is creating licensing issues for programs I am running.

Is there was to keep the same hardware ID?

Answer 1

By default the MAC is dynamic but can be configured static if desired.

Hi,

Firstly, we can contact the program vendor/developer to check which hardware information it relies on. Most programs (using hardware ID licensing) rely on the hardware information documented in this article.

Different virtualization platform may have different method to handle the virtual machine UUID. For hyper-v, the information is defined as below:

How to use uniquely identify a virtual machine in Hyper-V
https://learn.microsoft.com/en-us/archive/blogs/jhoward/how-to-use-uniquely-identify-a-virtual-machine-in-hyper-v

If the guest OS is windows, the information can be retrieved via below VB Script. And we may check this to see if it changes everyday. If this is fixed, the program may not rely on this.

If we are runing a linux guest OS in hyper-v, we can use sudo dmidecode | grep UUID command to retrieve the information.

 Const wbemFlagReturnImmediately = &h10  
 Const wbemFlagForwardOnly = &h20  
 Set objWMIService = GetObject("winmgmts:\\.\root\CIMV2")   
 set colBIOS = objWMIService.ExecQuery( _  
  "SELECT SerialNumber FROM Win32_BIOS", _  
  "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)   
 set colBB = objWMIService.ExecQuery( _  
  "SELECT SerialNumber FROM " & _  
  "Win32_BaseBoard", _  
  "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)   
 Set colSE = objWMIService.ExecQuery( _  
  "SELECT SerialNumber,SMBIOSAssetTag " & _  
  "FROM Win32_SystemEnclosure", _  
  "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)   
 For Each objItem in colBIOS  
    WScript.Echo _  
      "BIOS:            SerialNumber:   " & _  
      objItem.SerialNumber  
 Next   
 For Each objItem in colBB  
    WScript.Echo _  
      "Baseboard:       SerialNumber:   " & _  
      objItem.SerialNumber  
 Next   
 For Each objItem In colSE  
    WScript.Echo _  
      "SystemEnclosure: SerialNumber:   " & _  
      objItem.SerialNumber  
    WScript.Echo _  
      "SystemEnclosure: SMBIOSAssetTag: " & _  
      objItem.SMBIOSAssetTag  
 Next
