没有安装内核驱动程序(rc =-1908)在 macOS Big Sur 11.0.1中出错

我只是想使用 VirtualBox，但现在我得到了这种类型的错误。

我找不到合适的解决办法。

Kernel driver not installed (rc=-1908)


Make sure the kernel module has been loaded successfully.


where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

Big Sur disables the VirtualBox kernel extensions as part of the installation process. You can verify this by running:

kextstat | grep -v com.apple

If the kernel extensions are installed, you will see something like this:

Executing: /usr/bin/kmutil showloaded

If you don't see the extensions loaded, the easier fix is to delete your current VirtualBox app, download and install the lastest version and then go the Security & Privacy System Preferences Pane. You should see a message that some applications require a restart to work correctly.

Restart your Mac and VirtualBox should now work. You can re-run the kexstat command just to be sure the extensions were loaded.

MAC with BIG SUR -- Kernel driver not installed (rc=-1908)

Make sure the kernel module has been loaded successfully.

where the error is:

suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

Download and install the latest VirtualBox 6.1.18 or higher. And then follow the below steps to resolve.

Step 1 - run:

sudo kextload -b org.virtualbox.kext.VBoxDrv

Step 2: Go into System Preferences->Security & Privacy

Step 3: Unlock the security center

Step 4: Approve the software by Oracle

Step 5:

sudo kextload -b org.virtualbox.kext.VBoxNetFlt
sudo kextload -b org.virtualbox.kext.VBoxNetAdp
sudo kextload -b org.virtualbox.kext.VBoxUSB

Step 6: Reboot

Registering the .kext directly via terminal solved this issue for me.

sudo kmutil load -p '/Library/Application Support/VirtualBox/VBoxDrv.kext'

There should be a prompt in System Preferences to allow the kernel, which will require a reboot.

Reboot and run command cd ˜/Homestead && vagrant up

I had face this issue before and I tried all the threads in this question and doesn't work, then I tried to add the iso file from the setting tab like shown in screenshots, and it worked well.

VirtualBox kernel error

I also got the same error while trying to run Windows 10 on macOS Big Sur 11.6, but I was easily able to fix the issue by navigating to System Preferences > Security & Privacy. There, under allow apps downloaded from section I found something like Oracle wants to install additional updates, and I gave permission. My Win 10 VM started to work. I hope this help.

Here is how I solved the issue on MAC with MONTEREY

Update 09 december 2021 : installing the latest version (VirtualBox-6.1.30-148432-OSX.dmg when updating this post) completely solve the issue on my machine

Initial post :

  1. Download the latest installer of VirtualBox (VirtualBox-6.1.28-147628-OSX.dmg when writing this post)
  2. Launch the installer
  3. Double click on the file VirtualBox_Uninstall.tool in order to uninstall VirtualBox
  4. Reboot
  5. Reinstall VirtualBox
小开

Solution worked for Big Sur (no need to delete anything):

  1. Update VirtualBox
  2. Install VirtualBox Extension Pack https://www.virtualbox.org/wiki/Downloads
  3. Settings -> Security -> General settings -> Unlock settings
  4. On "General settings" form turn allow application usage checkbox from "App Store and others..." to "App Store" and back to "App Store and others..." (to make sure Mac recognised the changes made before on steps 1-2)
  5. Go to "Additional settings" ("General settings" form button right after application usage checkbox), system will show Applications changes made before (steps 1-2), push "Ok" and system will ask for reboot
  6. After reboot VirtualBox will work

after googling for few days and no solution worked for me on macos

I run the below commands

sudo kextload -b org.virtualbox.kext.VBoxDrv
sudo kextload -b org.virtualbox.kext.VBoxNetFlt
sudo kextload -b org.virtualbox.kext.VBoxNetAdp
sudo kextload -b org.virtualbox.kext.VBoxUSB

then go to "https://www.virtualbox.org/wiki/Downloads" and download "VirtualBox 6.1.30 Oracle VM VirtualBox Extension Pack" all platform

then open your virutalbox preferences --> choose extension --> and add the extension you just downloaded and eveything will be ok

Another restart of the system solved my problem as I was already at the most current version of virtualbox. My macOS upgrade was from Big Sur 11.6.1 to 11.6.4.

None of the methods here worked for me, the option to approve the driver in System Preferences / Security & Privacy never appeared.

The only way I could get to approve the extension was rebooting in recovery mode, and then giving consent to the Oracle Developr ID running in the Terminal the following command:

spctl kext-consent add VB5E2TV963

Then after a reboot, I could approve the driver and VirtualBox works just fine. Tested in Monterey 12.3.1

I started getting this issue when my Mac updated from Big Sur to Monterey. I just downloaded and installed the latest version of VirtualBox on my Mac and it started working like earlier.

小开

On MacOS Monterey 12.4, I just installed the latest version and opened VirtualBox (version 6.1.34 r150636 (Qt5.6.3)). Then:

Step 1: Went into System Preferences->Security & Privacy.

Step 2: Unlocked the security center.

Step 3: Approved the software by Oracle.

I haven't uninstalled my old virtualBox or restarted the machine or typed any code.

I couldn't make the option to allow the kext appear in System Preferences either. Rebooting, reinstalling VBox and running sudo kextload -b org.virtualbox.kext.VBoxDrv didn't help.

I discovered another cause: in my case, I had to enable WiFi for internet access and also allow syspolicyd to contact api.apple-cloudkit.com in Little Snitch (it is allowed by default, but I'd disabled that rule). Then running sudo kextload -b org.virtualbox.kext.VBoxDrv forced syspolicyd to verify the signature (or whatever my data it may be uploading) — the option appeared in Security & Privacy and I could allow it finally.

So if anyone has such an issue, try verifying that syspolicyd can contact api.apple-cloudkit.com.

(I also posted this discovery on my blog: https://egeek.me/2022/06/25/kexts-for-virtualbox-do-not-load/).
