Hello,
I have been unable to boot up a windows 10 virtual machine on my windows 10 host machine. I downloaded the VM for a class from my instructor's website and other students have successfully been able to boot up the VM. I also have a kali linux VM on my machine which works.
Attached is a screenshot and a zip file of my log

Re: Guru Meditation Critical Error
Your log contains these lines:
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. 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. See I have a 64bit host, but can't install 64bit guests. This tutorial has a couple more things to look for in step 2. Be sure these are all turned off.
3. Find the Command Prompt icon, right click it and choose Run As Administrator.
4. Enter this command:
If your Virtualbox does not start successfully, zip and post another vbox.log. For further info, see https://www.tenforums.com/tutorials/139 ... puter.html

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. If your Virtualbox does not start successfully, zip and post another vbox.log. For further info, see https://www.tenforums.com/tutorials/139 ... puter.html
