[Solved] Starting VM crashes host

Hi

My host is Ubuntu 16.04 LTS (64 bit), running on a new (September 2017) HP Zbook laptop with a Nvidia Quadro M2200 graphics card.
My linux kernel is currently 4.13.0-26-generic.
I have VirtualBox 5.0.40_Ubuntu r115130 running windows 10 (64 bit) as guest.
The system has 15.8Gb of RAM. The virtual machine has access to 9Gb of RAM.

Since last september, everything has been working great. But last week I tried to install (for the first time) the drivers for the Quadro.
It was then that I performed a series of system updates & upgrades (including new linux headers) which broke the virtual machine.
Now, everytime I try to start guest the host system crashes and I have to power-off and restart the computer.

As far as I know, guest additions were installed in the guest - I have didn't set up the VM, but in ~/.config/VirtualBox I do have the iso image VBoxGuestAdditions_5.0.40.iso and VM did work well for several months.

Right now, I do not have either a VBoxStartup.log or VBoxHardening.log.

My VBoxSVC.log file is attached. The log files for the VM are void.

I tried setting the file permissions for nvidiactl, nvidia-modeset and nvidia-uvm in /dev/ to 0666, but this had no effect.

When updating and upgrading the system virtualbox-guest-utils was removed. If I try to reinstall it apt says it will delete xorg. That scares me so I have not tried.

Both dkms and virtualbox-dkms are installed. Following the update of the linux headers I did run sudo modprobe vboxdrv.

I do not know what I should try next.

Completely remove/uninstall/delete/purge that version (that's the Ubuntu fork) and install the latest test build.
