One of four kext not loading

[Nutellinoit]

Hi everyone, i'm struggling to install virtualbox on Mac OS 10.13.3. It was working 10 days ago, then i got error when using vagrant with network reconfiguration

Code: Select all

VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory

I tried reinstalling, with brew, uninstalling, installing with latest version dmg, uninstalling. The output of kextstat shows 3 extensions loaded but no org.virtualbox.kext.VBoxNetAdp

Code: Select all

$ kextstat | grep virtualbox
  211    2 0xffffff7f839ed000 0x63000    0x63000    org.virtualbox.kext.VBoxDrv (5.2.6) C32CCC8B-7E44-3974-BEC0-9C1FA570690D <7 5 4 3 1>

When loading extensions with this script

Code: Select all

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/"

only sudo kextload "/Library/Application Support/VirtualBox/VBoxNetAdp.kext" -r "/Library/Application Support/VirtualBox/" fails

What i'm missing?

when using vagrant

Vagrant is a program that relies on VirtualBox but modifies its configuration files in unknown ways to us. It is not supported on these VirtualBox user forums, they have their own Vagrant support channels. If you are having this problem with a standalone version of VirtualBox, then we can continue this discussion.

I tried reinstalling, with brew

What does brew have to do with it? If you start including widely system modifying tools (brew, macports, etc.) be aware that we can't easily reproduce your setup, nor figure out exactly what fails...

[Nutellinoit]

Ok, I removed vagrant from system and uninstalled (using VirtualBox_Uninstall.tool) and reinstalled virtualbox using the official installer (VirtualBox-5.2.6-120293-OSX.dmg).

The problem remains the same, 3 kext loaded but VBoxNetAdp.kext fails

[socratis]

Try the "kextload" with the highest verbosity level and see what it comes out with. Or try "kextutil" (man kextutil). I don't remember seeing this single point of failure before. Usually its all or none...

And I'm not sure if uninstalling VirtualBox undid "whatever" your modifications have done to the system.

The error message "VBoxAdp: failed to register control device." means that the cdevsw_add() call failed. Which in turns means that the OS is out of available slots for devices. You need to complain to Apple about that (seriously).

OS X has a pretty low limit on the number of character device nodes which can be registered. The limit hasn't changed in ages but Apple keeps adding kexts to the OS which use up more and more slots. So once you install 2-3 third party packages, you're out of available slots and out of luck. Rebooting the host may or may not help. Uninstalling 3rd party packages which register their own character device drivers will help.

To be clear, this is something no one but Apple can solve.

Thank you michaln. I will try to uninstall the programs that load kext. they are not too many

Right, not too many. But we're talking about maybe a dozen or fewer device slots available for all 3rd party software. Then every single one can make a difference.

Find one culprit

Code: Select all

sudo kextunload -b com.intel.kext.intelhaxm

I think this was a leftover from a previus vmware fusion install. I don't understand why everything was working 10 days ago

[michaln]

Most likely because some other kext wasn't loaded. To be clear, only loaded kexts matter, not what's installed on disk.

Errata corrige, this is a kext used by android studio emulator...
