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).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

1) I have run below command in powershell with admin mode:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

2) run below command in command prompt with admin mode:

bcdedit /set hypervisorlaunchtype off 

3) disabled Hyper-V: Control Panel\Programs\Programs and Features\

4) VMBox memory made it to: 3155 MB (VMbox->settings->system)

VM box Acceleration is deactivated. How do activate this? and fix above error?

OS: windows 10.

rebooted Del laptop many times.

回答1:

You need to disable Hypervisior to check new application that use VT-x before ir launch.

So, follow the next steps:

1) open command prompt as Administrator

2) run bcdedit to check hypervisor status:

bcdedit

3) check hypervisor launch type:

4) if is set to auto then disable it:

bcdedit /set hypervisorlaunchtype off

5) reboot host machine and launch VirtualBox again

I hope this helps.

Disabling Device Guard or Credential Guard fixed for me:

• 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.
• Go to Control Panel > Uninstall a Program > Turn Windows features on or off to turn off Hyper-V.

Select. Do not restart.

Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:

mountvol X: /s
copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y
bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"
bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS 
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
mountvol X: /d

Note: Ensure X is an unused drive, else change to another drive.

Restart the host. Accept the prompt on the boot screen to disable Device Guard or Credential Guard.

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

To check the status of Hyper-v in Windows 10,

right click <"start"> → Run → OptionalFeatures.exe, → look for the "Hyper-V" option.

The box should be empty, not checked or shaded.

Make sure to fully power down and reboot the host after changing the Hyper-v setting.

PS

Docker known for activating this "Hyper-V" without asking for user opinion and then Oracle VirtualBox does not want to work.

You need to disable the windows Hyper-V feature and bcd. Then Virtual Box will run in latest Windows 10 versions (Jan-Mar 2018). Windows 10 Hyper-V is having clash on VirtualBox features.

I have resolved this by following steps-

1. bcdedit /set hypervisorlaunchtype off
2. Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
3. Restart your windows

Detailed discussion on this are available at - https://forums.virtualbox.org/viewtopic.php?f=6&t=87237

Alternatively you can install linux (Ubuntu) in Windows 10 from the latest bash command - https://www.windowscentral.com/how-install-bash-shell-command-line-windows-10

回答6:

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.

Finally I can fix the issue now.

At first, we need to identify or understand the problem which mostly people not really findout, my VM is came with guest OS of Ubuntu 64-bits but after import, we check on that VM it shows only 32-bits OS.

When we start the VM, we got error as:

Failed to open a session for the virtual machine ERPNext-Develop-20180331192506.

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

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I did try above solutions, somehow not really work or I might miss something.

Then I notice the point above (32-bits OS) so I think the problem might be with this one.

With some posts around the Internet, it could explain that Windows 10 also comes with the Hyper-V which is conflict with Oracle VM VirtualBox.

So solution I did...

1. Disable Virtualization Based Security in group policy

• Start Run application and start: gpedit.msc
• Go to Computer configuration > Administrative Template > Device Guard

2. Disable Microsoft Hyper-V

   • Start Run application and start: OptionalFeatures.exe
   • Untick: Hyper-V
   • Restart the PC

Then we can use the VM, it's started. Among the two steps above, I believe that step 2 is really solved.

Anyway, please try it and let's know if it helps.

As in the docs, if you are on windows you can use hyperv drivers.

Docker for Windows - You can use docker-machine create with the hyperv driver to create additional local machines.

I have exactly the same question and have done the same things as you with no success.

I found an entries in my log of

I have tried the following, but it didn't work for me.

From this thread https://forums.virtualbox.org/viewtopic.php?t=77120#p383348 I tried disabling Device Guard but Windows wouldn't shut down so I reenabled it.

I used this path .... 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.

After Windows 10 update in July of 2018 I suddenly experienced this issue with Virtual Box losing 64-Bit OS options resulting in the error.

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

Existing Laravel Homestead Boxes rendered un-bootable as a result event though HYPER-V is Disabled / Not Installed...

The FIX! (That worked for me) Drum Roll....

Install Hyper-V... Reboot, Uninstall it again... Reboot... The end

Run CMD in administrator mode 1.bcdedit 2.bcdedit /set hypervisorlaunchtype off 3.Reboot system

This worked for me!!

I wanted learn how to use vagrant with virtualbox, when I got the error message 'Raw-mode is unavailable courtesy of Hyper-V'. To fix this issue, I think I made all of the suggested changes above (thank you guys), and some more.

Let me summarize:

( cmd: optionalfeatures )
Turn off 'Hyper-V'
Turn off 'Containers'
Turn off 'Windows Subsystem for Linux'

cmd: bcdedit /set hypervisorlaunchtype off

( cmd: gpedit.msc )
Local Computer Policy -> Computer Configuration -> Administrative Templates -> System -> Device Guard ->
Disable 'Turn On Virtualization Based Security'

Settings -> Update & Security -> Windows Security -> Device Security -> Core isolation details -> Memory integrity -> Off

This would be the easiest way.

1) go and download the Device Guard and Credential Guard hardware readiness tool here- https://www.microsoft.com/en-us/download/details.aspx?id=53337

2) Find the folder path of "DG_Readiness_Tool_v3.5.ps1" of downloaded content and run the below command after enable Powershell "unrestricted". "./DG_Readiness_Tool_v3.5.ps1 -Disable -AutoReboot"

3) When rebooting the machine press F3 to confirm to disable the features
