virtualbox.org

One of the new security features in Windows 10 is Credential Guard. It essentially virtualizes the LSA to isolate security operations (opposed to credentials being stored in process memory like in traditional LSA). To make use of this, you must enable the Hyper-V Hypervisor, which always conflicts with VirtualBox. Does anyone know if it is possible to enable this feature while still using VirtualBox?

No, it won't be possible. The hypervisor loads before the OS and assigns hardware virtualization to the hypervisor, not the host OS. VirtualBox cannot use hardware virtualization if the Hyper-V hypervisor is active.

You could try this:

On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.
Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.
Select Disabled.

Had me fix 2 problems:

Crashing Windows 10 when starting a Guest VM in VirtualBox
Still being able to use Hyper-V

How exactly were you able to use Hyper-V and VirtualBox? Could you explain that? I can see the Virtualization Based Security option, but I can't see how Hyper-V would be enabled and VirtualBox running. Maybe you meant:

Hi

I assume if you enable hyper-v on Windows 10 you can no longer use virtualbox

which appeared to be the case with xpmode running under windows7.
I have a windows10 Pro with 50gig of ram and have been using Virtualbox for sometime without a problem.
I had a old windowsXP image I ran when I was using Windows7 xp mode and wondered if it would still work with Hyper-V I enabled hyper-v then disabled it now virtualbox will not work I get the error

AMD-V is not available (VERR_SVM_NO_SVM).


Result Code:
E_FAIL (0x80004005)

I noticed if I ran xpmode in Windows 7 it would not run virtualbox untill I rebooted.
I have a asus M5A99X motherboard and trying to run a Debian image Virtualbox version Version 5.1.14 r112924 (Qt5.6.2)

Your problem seems to have nothing in common with the title of this thread "VirtualBox Compatibility with Device Guard/Credential Guard", but with XP-Mode. Please pick an appropriate thread, or even better, open a new one...
