All VMs Crash and will not start

[Nathan2020]

Hi - I had been using Virtual Box successfully for a few months. Lately, it started crashing every time I start the VM. It does this with a new VMs and pre-existing VMs.

For a clean test, I updated Virtual Box, install the latest extensions, and tried to create a brand new 64 bit Windows 2019 VM - same results. It will start loading files from the Windows CD, then crash once the windows logo first displays.

What could be causing this?

In addition to the problem Mpack noted with the mismatched Extension Pack, you host's Hyper-V is enabled.

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: The choice of animal is appropriate: Your guest is running, just really slow. Or it might guru-meditate or crash. 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 () 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. Look into I have a 64bit host, but can't install 64bit guests, 2nd post, points 2 & 3 and ensure that none of these things are running.

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

4. Enter this command:

bcdedit /set hypervisorlaunchtype off

5. Enter this command:

shutdown -s -t 2

6. 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.
