Fail to install Fedora 32

[masuqur]

Hello,

I need help to install Fedora 32 in VirtualBox.

During installation it automatically stop and redirect to log in screen.

I tried other version 31 and also CentOS 7. But I didn't able to install any of it.

I don't know where is the problem. Please help. My machine is windows 10.

Thanks
Masuqur

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.

Thank you! I enabled Hyper-V to test out Ubuntu. When I turned it off and tried to reinstall Ubuntu, I was met with a ton of confusing issues. I was genuinely frustrated until I accidentally came across this post. Those steps you listed in the other link were the solution. I am now afraid to mess with Hyper-V now! Thanks again. I am not sure how long I would have spent fighting it.

Thank you scouttgus1.

Your solution works for me.

The problem happened when I update windows, with version 2004 which has the Microsoft Hyper-V. Disabling it works perfect.

Thanks

It seems that major version updates of Windows hosts will turn on Hyper-V again, and require the turn-off. Just something to remember.

Glad you're up and running!
