virtualbox.org

I've always been able to run Linux VMs on my Windows host, but for some reason no distro is working for me.

I've tried Ubuntu, Kali Linux, ElementaryOS, and they all freeze when it's time to boot.

Kali Linux Live - when the dragon is loading with the blue glow, it just freezes and stays like that
Elementary OS Live - when the E logo is loading, it freezes and stays like that
Ubuntu 20.02 - After performing the initial disk check, the loading circle appears. It freezes and stays like that.

I've tried different ram allocations, different allocated cpus, graphics controller differences, network adapter differences, and they all fail when it is time to boot. I have virtualization enabled, and my android emulator with qemu works perfectly fine, but I've been at this for 6 days hours at a time and I just have no idea what could be the problem. I would appreciate if someone can help me with this as I am stumped, and I can't possibly be the only one experiencing this if my settings are equivalent to an average user.

In case it helps:
Intel i5 3350P
AMD Rx 560

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. 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:

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.

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

rnadler's link shows the same cause, Hyper-V is enabled.

Thank You very much! It works perfectly, I've been trying to figure this out for so long, I really appreciate the response!

Good, glad you're up and running!
