Critical Error on when installing windows server 2019 standard

Post by Anarchy »

I downloaded the ISO from Microsoft site 3 different times to ensure I got the complete file. I've set my graphics controller to vboxvga and Vboxsvga. Cpu cores are set to 2. Video memory will only goto 128MB for server 2019. I still keep getting Critical error when trying to start the server to run the setup. I have read and tried to setup using recommendations in other posts concerning critical errors when setting up a server in virtualbox.

Your log contains these lines:
{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

You might notice in the guest window's Status Bar the green turtle: Image The choice of animal is appropriate: Your guest is running, just really slow. This is because a service that uses Microsoft Hyper-V is running on your host PC. Normally Hyper-V blocks Virtualbox. But your PC is of the type and OS where Virtualbox can attempt to run the guest using the Hyper-V engine. This arrangement is still being developed and isn't 100% yet.

If VirtualBox is running without Hyper-V enabled, and nothing else is interfering with hardware virtualization (VT-x / AMD-V), then the usual virtualization icon (Image) will be seen in the Status Bar.

To turn Hyper-V off completely, do this:

1. Shut down all programs. You will have to reboot your host.

2. Find the Command Prompt icon, right click it and choose Run As Administrator.

3. Enter this command:
bcdedit /set hypervisorlaunchtype off
4. Enter this command:
shutdown -s -t 2
5. When the computer turns off, unplug it for 20 seconds. Then plug it in again and boot up Windows 10.

Your Virtualbox should be running now. If the green turtle still appears and the tell-tale lines are in the log, try all the steps again. If you don't get the standard virtualization icon, post back exactly what you did and we'll try to help some more.

bcdedit /set hypervisorlaunchtype off

...followed by a reboot did the trick for me :)

Thank you very much!
