I reinstalled the same version of VirtualBox, and it worked. I think the reason was because when I firist installed VirtualBox, it said it had failed because the OS blocked some installation thing. So I went to System Preferences, Security, and there was a message something like “The installation from Oracle was blocked”. I approved it, and thought that would be that.

But it didn’t work. However, as I say I re-installed it and I guess the OS remembered that I approved installation so it worked without a problem this time.

I had given up, fail forever to install kubernetes, maybe because i am in china

I had this problem running on Arch Linux. It was caused by the virtualbox kernel modules for network not being loaded correctly after a new installation of virtualbox. After a reboot the correct kernel modules were loaded and Minikube ran as normal.

The required network modules are:

% lsmod | grep vbox
vboxnetflt             32768  0
vboxnetadp             28672  0
vboxpci                28672  0
vboxdrv               483328  3 vboxnetadp,vboxnetflt,vboxpci

I did not have to reinstall virtualbox to fix this problem – I just needed to reboot.

sudo modprobe vboxnetadp

MacOS Solution

Run the following shell(Root is necessary)

#!/bin/bash

unload() {
        if [ `ps -ef | grep -c VirtualBox$` -ne 0 ]
        then
                echo "VirtualBox still seems to be running. Please investigate!!"
                exit 1;
        elif [ `ps -ef | grep -c [V]ir` -gt 0 ]
        then
                echo "Stopping running processes before unloading Kernel Extensions"
                ps -ef | grep [V]ir | awk '{print $2}' | xargs kill
        fi
        echo "Unloading Kernel Extensions"
        kextstat | grep "org.virtualbox.kext.VBoxUSB" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxUSB
        kextstat | grep "org.virtualbox.kext.VBoxNetFlt" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxNetFlt
        kextstat | grep "org.virtualbox.kext.VBoxNetAdp" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxNetAdp
        kextstat | grep "org.virtualbox.kext.VBoxDrv" > /dev/null 2>&1 && sudo kextunload -b org.virtualbox.kext.VBoxDrv
}

load() {
        echo "Loading Kernel Extentions"
        sudo kextload "/Library/Application Support/VirtualBox/VBoxDrv.kext" -r "/Library/Application Support/VirtualBox/"
        sudo kextload "/Library/Application Support/VirtualBox/VBoxNetAdp.kext" -r "/Library/Application Support/VirtualBox/"
        sudo kextload "/Library/Application Support/VirtualBox/VBoxNetFlt.kext" -r "/Library/Application Support/VirtualBox/"
        sudo kextload "/Library/Application Support/VirtualBox/VBoxUSB.kext" -r "/Library/Application Support/VirtualBox/"
}

case "$1" in
        unload|remove)
                unload
                ;;
        load)
                load
                ;;
        *|reload)
                unload
                load
                ;;
esac

MacOS open System Preferences → Security & Privacy → General Click Allow

Last, rerun brew cask reinstall virtualbox

Perfectly resolved for me

I experienced on Windows 10 that you should restart after installing VirtualBox.

Minikube and Ubuntu 16.04 have been a horrible experience. I have reinstalled virtualbox multiple times and tried multiple different versions. This is really disappointing.

On Ubuntu Linux, there were a few things I needed to check with VirtualBox:

1. First, ensure the latest kernel modules have been built

sudo vboxconfig

If you are using SecureBoot, ensure these modules have been signed as well (you’ll have set up a process for this if you have used VirtualBox in the past)

1. Ensure the relevant vbox modules are loaded into the kernel

sudo modprobe vboxdrv vboxnetadp vboxnetflt vboxpci

You can check their output by tailing dmesg, or list them out by running ls /lib/modules/`uname -r`/misc 3. Lastly ensure that you have an VirtualBox interface that can be used as a host-only network. This can be done in the UI by going to File->Host Network Manager (and clicking Create if one isn’t available) or by running VBoxManage hostonlyif create to create a new one

Ok so on Mac I had the same issue, here’s my flow (now it’s fixed):

INSTALLATION ISSUE

1. Download VirtualBox, start installation
2. Installation failed, some security thing was not accepted
3. Opened settings as suggested, accepted this security thing
4. Closed the installer and assumed it’s all good now <-- ISSUE
5. Downloaded and installed all Kubernetes stuff
6. Tried to run minikube start, failure as described in this ticket

RE-INSTALLATION ATTEMPTS

1. Move VirtualBox from Applications to Trash <-- NO, DOESN’T WORK
2. Reinstall VirtualBox (installation failure)
3. Open VirtualBox installer .dmg, run the uninstaller tool
4. Reinstall VirtualBox (installation failure) <-- NO, DOESN’T WORK

SOLUTION, AFTER EVERYTHING ELSE FAILED…

1. Open VirtualBox installer .dmg, run the uninstaller tool
2. RESTART OS
3. Open VirtualBox installer .dmg, run the installer again (security thing is now accepted)
4. RESTART OS
5. Run minikube start

So trial and error. Should be fixed by Oracle I think, this installer fails by default… but hey, they must be really busy with other stuff…

Thanks, that was it @alienscience. Also I needed the virtualbox-host-modules-arch instead of the default one suggested when installing virtualbox.

I didn’t reboot but just loaded the kernel modules manually.

It looks to me like this error message is somewhat misleading. For me, it wasn’t really anything to do with a virtualbox known bug or a version higher that 5.0.12. However, it was an issue with how virtualbox was installed. If you get this error, first try running minikube VM manually under virtualbox. More applicable errors are shown there.

I ended up removing and reinstalling virtualbox with the correct kernel modules. I then needed to manually delete the previously created minikube VM in virualbox followed by a minikube delete so that minikube would create a valid VM.

Now at least minikube start completes without errors.

I had same issue on OSX, and struggled a lot until I tried to install VirtualBox with Cask which printed the following:

virtualbox requires a kernel extension to work.
If the installation fails, retry after you enable it in:
  System Preferences → Security & Privacy → General

For more information, refer to vendor documentation or this Apple Technical Note:
  https://developer.apple.com/library/content/technotes/tn2459/_index.html

Allowing Orance Inc. developer in System Preferences → Security & Privacy → General fixed the problem.

Uninstalling und reinstalling with the exact installer works. If you use the windows uninstall tools I had no luck.

Try to reinstall virtualbox with the same installer or run the networking setup tool. The host-only network (default) needs to exist as this is needed for initial and ssh communication.

Rebooting the system after installing VirtualBox worked for me (MacOS Mojave 10.14.3)

Clear reinstall of VirtualBox helped me. Mac OS High Sierra 10.13.4 Beta4, minikube v0.25.0. VirtualBox v5.2.8 r121009

I just used the kvm2 hypervisor, which works very well.

I’m getting this too, on NixOS 17.09

• minikube v0.21.0
• virtualbox 5.1.32
• kubectl 1.7.9

The version constraint in the error message is clearly incorrect, since I’m on VirtualBox 5.1.32 and still getting this
