virtualbox Raw-mode is unavailable courtesy of Hyper-V windows 10

Question

issues:

Failed to open a session for the virtual machine ubuntu.

Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).

Resul         


        

Answer 1

1. disabled Hyper-V (Control Panel\Programs\Programs and Features\ Hyper-V)

   

2. modify BCD (bcdedit /set hypervisorlaunchtype off)

   

3. If core isolation is enabled, turn it off (Windows Defender Security Center> Device Security> Core Quarantine)

   

If you cannot modify it, you can change the value of HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ DeviceGuard \ Scenarios \ HypervisorEnforcedCode Integrity \ Enabled in the registry to 0

Answer 2

You have to disable Memory Integrity.

Go to Device Security, then Core Isolation, disable Memory Integrity and reboot.

It seems that Memory Integrity virtualizes some processes (in this case, VMware) and we get that error.

You can also disable Memory Integrity from Registry Editor if your control panel was saying 'This is managed by your administrator'.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity

Double click on Enabled and change its value from 1 to 0 to disable it.
