Critical error when installing Windows Server 2019

[WB2020]

Hi,

I want to install Windows serveur 2019 on Virtual Box.

The ISO is the official one from microsoft for evaluation

But when I launch it for first time I got this error message saying

A critical error happened during execution of the VM and this one has been turned off

the last log before the error are :

00:00:52.195073 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have successfully installed others ISO such as Windows Server 2016, Ubuntu, Windows 10..

I have uninstalled and installed latest version of VirtualBox.

Any idea what is going wrong and how to solve it ?

Thank you in advance,

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, the 2019 template may have a bug in it. Make a new VM, use the 2016 template for Server 2019, and make sure that the VM's System settings, Acceleration, Paravirtualization Interface* says 'Hyper-V'.

(* 'Paravirtualization Interface' is a comm channel for virtualization-aware OS's to talk to whatever hypervisor is running them, so they can run more efficiently. Setting this to Hyper-V does not turn on the host OS's Hyper-V.)

If none of this helps, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.
