I have downloaded Centos OS from osboxes dot org/virtualbox-images and added in to my Virtual Box. But due to some reason my centos OS not booting. Giving me some "GURU" message.
Seeks experts advice to fix my issue.

I have installed the Oracle VM Virtual Box 6.1 in my Laptop running Windows 10 Home.
My Processor : Intel Core i7-3630, 2.40 GHZ, 8 GB
Make : HP ENVY DV7
Virtualization Technology in BIOS - Enabled

Attached vbox and vboxhardening logs

Thanks and Regards

The hardening log has an exit code of 0 so no hardening issues.

Your vbox.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...

This is because a service that uses Microsoft Hyper-V is running on your host PC. Normally Hyper-V blocks Virtualbox.

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.

If your Virtualbox does not start successfully, see I have a 64bit host, but can't install 64bit guests. The 64-bits tutorial has a couple more things to look for in step 2. For further info, see https://www.tenforums.com/tutorials/139 ... puter.html
