VirtualBox 6.0 and Hyper-V
Re: VirtualBox 6.0 and Hyper-V
Re: VirtualBox 6.0 and Hyper-V
FYI, in the mean time I received additional information about VERR_NEM_MISSING_KERNEL_API: it's a known issue and we'll see that we fix it until the next release.
Re: VirtualBox 6.0 and Hyper-V
I am using Windows 10 Enteprise LTSC 2019 edition - maybe that does the trick. Also, I have active WLS subsystem, and this is the reason I need VirtualBox working along with enabled Hyper-V instead of switching it off.klaus wrote:I wonder if there are API availability differences between the Windows 10 editions, i.e. Home/Pro (and maybe the S mode also has an effect)
Re: VirtualBox 6.0 and Hyper-V
Seeing as how the Hypervisor Platform API is so broken. And also if it works the performance is not good.
Would it not be better (at least on Intel) to enable
for the main Windows 10 OS client of Hyper-V?
So that VirtualBox can run its own virtualization on top?
I don't know what to put for the VMName though. Is this feasible?

Re: VirtualBox 6.0 and Hyper-V
i have a problem with that as well my host windows 10 and i wanna run windows 7 as a vm.
i have tried everything regarding hyper-v and i am sure its disabled.
from the windows feature hyper- v and container and windows sand box and virtual machine plat form all r disabled and i used the CMD to disable hyper.
mine still doesn't work and it gives the turtle icon instead of the V. please any help will be appreciated.

Re: VirtualBox 6.0 and Hyper-V
Have you used the bcdedit command to prevent the hypervisor from loading, and rebooted at least once (preferably twice)?
bcdedit /set hypervisorlaunchtype Off
If you are getting the turtle, the hypervisor is still loading and VirtualBox cannot use hardware virtualization.

Re: VirtualBox 6.0 and Hyper-V
yes and even i ADD the option that when i start my computer it asks me if i need a Hyper-V TO WORK OR WITHOUT.
ANY HELP WILL BE REALLY APPRECIATED I REALLY WANT VIRTUAL BOX TO WORK.
THANK U SO MUCH!!

Re: VirtualBox 6.0 and Hyper-V
Next week there will be a new release, and while it doesn't have much actual change in this code area, it will give better diagnostics to figure out what exactly is going wrong. Our developer couldn't reproduce any trouble with recent Windows 10 releases and the Insider Preview as of some weeks ago.

But I *want* Hyper-V to run. So I can use Credential Guard, WSL 2.0, etc.BillG wrote:Have you used the bcdedit command to prevent the hypervisor from loading, and rebooted at least once (preferably twice)?

I just also want Hyper-V to expose/emulate VT-x ("ExposeVirtualizationExtensions" https://wibier.me/expose-virtualization ... l-machine/).
For some reason it can not be(?) enabled and instead Virtualbox is now bending over backwards to adopt Microsoft's virtualization backend.
Or am I missing something?
Re: VirtualBox 6.0 and Hyper-V
Yes, you're missing the fact that if Hyper-V is enabled then VirtualBox cannot use VT-x. All it can do is rely on Hyper-V. That's how Microsoft decided it has to be. You're running VirtualBox in the Hyper-V root domain (at least that's how I understand it) which never gets the virtualization extensions.kwinz wrote:But I *want* Hyper-V to run.

If you want to let VirtualBox use the emulated VT-x you need to create a separate Hyper-V VM and run VirtualBox there. May or may not work, we're not testing this case currently.

Re: VirtualBox 6.0 and Hyper-V
Hi kferhat and others with trouble starting VMs when Hyper-V is enabled.
To help reproduce / fix, I would very much like to know which windows features you have enabled in the "Turn Windows features on or off" list. Some screenshots with the enabled branches fully expanded would be nice.
At a minimum, could you report back whether the "Windows Hypervisor Platform" feature is enabled or not.
Cheers,
bird.

Re: VirtualBox 6.0 and Hyper-V
Hello Bird,
Thank you so much for the replay.
So I try everything : Enabling and disabling all the features.
I disabled also "Windows Hypervisor Platform" and get the same error.
Now this is the state is in the attachment.

Re: VirtualBox 6.0 and Hyper-V
Enabling only the Windows Hypervisor Platform and no other Hyper-V features will allow VirtualBox guests to run OK, but I think this is only because enabling only the Windows Hypervisor Platform does not change the hypervisorlaunchtype setting in bcdedit, so the hypervisor does not load, even after a reboot. As soon as the hypervisor loads, we are back to the turtle icon and VERY slow vm.
Windows 10 Pro build 18363.778 VirtualBox 6.1.6 .
Task manager shows VirtualBox Virtual Machine using 25-29% CPU
Much to my surprise, my 32-bit XP and Win2000 vms will run with this setup. Windows 7 x64 still at trying to start.
