19832,Virtual Box + Hyper-V - VERR_NEM_VM_CREATE_FAILED,mfr,,"We are running Win10 1909 Build 18363.959 with Hyper-V (CredentialGuard) enabled. We like to run VirtualBox (version 6.1.12) with VMs on the system.
When we fresh install virtualbox, everything is working fine. The VM can be started.
After a reboot of the system the VMs are not able to start anymore, with the following error: 
ERROR [COM]: aRC=E_FAIL (0x80004005) aIID={872da645-4a9b-1727-bee2-5585105b9eed} aComponent={ConsoleWrap} aText={Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED)}, preserve=false aResultDetail=-6805

After we completely uninstall virtualbox and do a new fresh installation of virtualbox, we are again able to start the vms. But again after a reboot the same error occurs again.

CPU - Intel Core i5-8365U

I looked up google, but any solution states to disable Hyper-V. But as we like to use Credential Guard this is no option for us. And why is it working after a reinstallation. ",defect,closed,other,VirtualBox 6.1.10,invalid,Hyper-V,,Windows,Windows
