Fix VirtualBox Kernel driver not installed (rc=-1908) on Mac
1Here's how to VirtualBox Kernel driver not installed (rc=-1908) on Mac.
The error message "Kernel driver not installed (rc=-1908)" occurs when VirtualBox is unable to load the kernel driver that it needs to run. This can happen for a variety of reasons, including:
* The kernel driver is not compatible with your operating system.
* The kernel driver is not installed correctly.
* The kernel driver is disabled in your system settings.
To fix this error, you can try the following steps:
1. Make sure that you are using a compatible operating system. VirtualBox supports a wide range of operating systems, but not all versions are compatible with each other.
2. Check if the kernel driver is installed correctly. You can do this by opening the VirtualBox Manager and going to the "Devices" menu. If the kernel driver is not installed, you will see an option to install it.
3. Enable the kernel driver in your system settings. You can do this by opening the "System Preferences" app and going to the "Security & Privacy" section. Under the "Privacy" tab, you will see a list of kernel extensions that are allowed to load. Make sure that the VirtualBox kernel extension is enabled.
If you have tried all of these steps and you are still getting the error message, you can try reinstalling VirtualBox. This will reinstall the kernel driver and hopefully fix the problem.
Here are some additional tips for troubleshooting the "Kernel driver not installed (rc=-1908)" error:
* If you are using a Mac, you can try disabling System Integrity Protection (SIP). SIP can prevent VirtualBox from loading the kernel driver. To disable SIP, you will need to restart your Mac in Recovery Mode and open the "Terminal" app. Once the Terminal app is open, type the following command and press Enter:
```
csrutil disable
```
* If you are using a Windows computer, you can try updating your drivers. You can do this by going to the manufacturer's website and downloading the latest drivers for your computer.
* If you are still having trouble, you can contact VirtualBox support for assistance.
i. The required kernel drivers for running VirtualBox for Mac are:
* **VirtualBox kernel extension:** This is the main kernel driver that VirtualBox needs to run. It is included in the VirtualBox installation package.
* **Guest Additions kernel extensions:** These kernel extensions are required for certain features of VirtualBox, such as shared folders and USB passthrough. They are not installed by default, but can be installed from the VirtualBox Manager.
To install the kernel drivers, follow these steps:
1. Open the VirtualBox Manager.
2. Go to the "Devices" menu and select "Install Guest Additions."
3. Follow the on-screen instructions.
Once the kernel drivers are installed, you should be able to run VirtualBox without any problems.
ii. suplibOsInit is a function in the VirtualBox kernel driver that is responsible for initializing the VirtualBox hypervisor. The hypervisor is a software layer that allows VirtualBox to run multiple operating systems on the same physical machine.
If suplibOsInit fails, it means that the VirtualBox kernel driver was not able to initialize the hypervisor. This can happen for a variety of reasons, including:
* The kernel driver is not compatible with your operating system.
* The kernel driver is not installed correctly.
* The kernel driver is disabled in your system settings.
* There is a problem with your hardware.
To fix this error, you can try the following steps:
