Public bug reported:

I'm running Virtualbox on Ubuntu 17.10 with several guest VMs. Not sure
when it was introduced, but for a while I've been running into issues
where the VMs refuse to start after upgrading them. Took me some time
and experimentations, but it seems to be triggered by the linux kernel
version in the VMs. It seems I'm able to upgrade any other packages, but
when upgrading the kernel version (kernel, imagge and header packages),
the VM will not start after a reboot.

For an example, this is the currently installed kernel on an Ubuntu bionic VM 
along with the available one which doesn't work:
$ apt policy linux-generic 

Could possibly be something in kernel 4.15.x which Virtualbox doesn't

I first suspected this was an issue with the VM in question, but I've
been able to reproduce this on VMs running Ubuntu bionic, 17.10 or
Debian unstable. (I also had an Arch linux vm which in retrospect seems
to have hit the same issue) This leads me to believe the issue is

When attempting to start the VM, it seems to load for a while
(presumably until it starts loading the kernel), I get the following
error message marked "Guru meditation":

"A critical error has occurred while running the virtual machine and the 
machine execution has been stopped.
For help, please see the Community section on or 
your support contract. Please provide the contents of the log file VBox.log and 
the image file VBox.png, which you can find in the /home/wizard/VirtualBox 
VMs/bionic/Logs directory, as well as a description of what you were doing when 
this error happened. Note that you can also access the above files by selecting 
Show Log from the Machine menu of the main VirtualBox window.
Press OK if you want to power off the machine or press Ignore if you want to 
leave it as is for debugging. Please note that debugging requires special 
knowledge and tools, so it is recommended to press OK now."

Currently I'm working around the issue by holding back kernel upgrades
in VMs, but I assume that new install of for instance bionic would ship
with a too new kernel to work.

Let me know if you have any questions or requests for additional
