Re: VirtualBox 6.0 and Hyper-V
WillFC, are you able to check which "Windows Features" are turned on/off on your installation? Some screenshots of the dialog with relevant branches expanded would be great, or at least listing the "Windows Hypervisor Platform" and "Hyper-V" branch.
Cheer,

I should also note I've spent a little time looking at software logs to see if any of the corporate nannyware might be blocking something, but don't see any indication of that.

Re: VirtualBox 6.0 and Hyper-V
I have been unable to get VirtualBox to run on my Windows 10 Machine unless I uncheck the Hyper-V feature and the Windows Virtualization Platform features.
I am attaching pngs of the VirtualBox About screen. My Windows feature screen. My Processor information and My Windows 10 Build and Version information.
I am also attaching the VirtualBox log. Some of the information is in another post because of the 3 attachment limitation on posts! See next post!
I would hope that a developer or somebody at Oracle would take a look and tell me what I am doing wrong. I have scoured these forums ND REBOOTED MY SYSTEM SO MANY TIMES TRYING TO GET IT TO WORK.
Any and all help appreciated.

Re: VirtualBox 6.0 and Hyper-V
Here are the rest of my pngs and the Log Files
And just for the sake of argument it does not matter if this is a docker provider or a vagrant file. I have tried this with Kali Linux and get the same results.
There is always an Invalid Settings Error. I can not use 64-bit OSs. They are not in the drop down list. I get the exact same Error Message.
AND YES VIRTUALIZATION IS TURNED ON IN THE BIOS!!!!

Re: VirtualBox 6.0 and Hyper-V
I've got a strange error while trying to get vbox use hyper-v backend.
I have both Hyper-V (all subelements) and Windows Hypervisor Platform features enabled. Virtual Machine Platform is not enabled.
It was the same before I enabled Windows Hypervisor Platform.
Windows is version 2004 19041.264 64-bit
VBox is on 6.1.6
The guest VM I'm trying to run is an empty VM (no virtual drives attached) set to "64-bit Debian Linux". Everything about VT-x nesting is not greyed out and enabled in VM config. Paravirtualization is set to Default.
Code: Select all
Cannot enable nested VT-x/AMD-V without nested-paging and unresricted guest execution!
(VERR_CPUM_INVALID_HWVIRT_CONFIG).

I also encountered problems since about three day and have tried several thing.
Three days ago I tested Windows Sandbox, afterwards my Virtualbox did not run anymore. I returned Sandbox settings but did not help.
I deleted whole Virtualbox environment and installed once again, did not help.

Re: VirtualBox 6.0 and Hyper-V
@banga, if you are trying to go back to no-Hyper-V Virtualbox, then there's things you can do:
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. 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
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...

Re: VirtualBox 6.0 and Hyper-V
On Windows 10 2004 (19041), with Hyper-V, Containers and Virtual Machine Platform enabled, I can run an Ubuntu 20.04 guest in Virtual Box 6.1.8 using PV set to Hyper-V (slow turtle mode). However, the guest is not stable. I experience segfaults, hangs and the computation of hashes like SHA256 fails, preventing me from successfully running apt-get update/install, for instance. It seems the feature is not yet ready for prime time.
I can't set hypervisorlaunchtype off as I need Docker on WSL2. I wish I could use VBox for my VMs instead of Hyper-V as the later has a few crucial shortcomings. With time we'll get there I guess.

Re: VirtualBox 6.0 and Hyper-V
As things stand, the only way to run both on the same PC is to have two loader entries for the OS, one with and one without the Windows hypervisor. You need a reboot to change modes.

Re: VirtualBox 6.0 and Hyper-V
The only way we will get this resolved for good without the buggy, and slow Hyper-V API is to have Microsoft enable nested virtualziation in the root domain.
According to Microsoft staff https://github.com/microsoft/WSL/issues ... -638409782 we are supposed to upvote on "user voice". This is the closest issue that I found: https://windowsserver.uservoice.com/for ... nested-vir Please upvote!

Here is my cautionary tale:
Running Linux on Virtualbox on a Windows 10 update 2004 host while having Hyper-V / WSL 2 active , I have managed to corrupt my entire Linux installation of a long running VM.
I had noticed random GUI applications like mate-terminal use 100% CPU and making the whole VM unresponsive. Firefox started randomly disappearing from screen.
I tried reinstalling the packages that were showing problems because I assumed some file corruptions in a low-level library, but finally wound up with an unbootable system.
Problems even occured when downloading software packages, the package manager refused to install them because of key corruptions (GPG issues) or checksum problems.
After all this had happened I did a memtest on the virtual machine which showed dozens of errors! A memtest on the host machine showed no problems.
After disabling Hyper-V, all problems went away and I was able to reinstall all packages using chroot - which was my luck.
Re: VirtualBox 6.0 and Hyper-V
VMWare is now officially supporting Hyper-V enabled Windows hosts: https://blogs.vmware.com/workstation/20 ... -mode.html
Even without nested virtualziation in the root domain... So it looks like it can be done without it... I suppose that the Hyper-V API would be stable from now on with the official Windows 10 2004 release and VMWare supporting running VMs on it while Hyper-V is enabled.
