Updating from kernel
4.16.2 to 4.17.2
gives us issues
We suspect the kernel and the Virtualbox additions are no longer compatible and the virtualbox additions need to be updated.
Extra interesting topics in the video
In the video I say it is a kernel issue… it is more a virtualbox issue. We actually need updates for VirtualBox to be able to work on the latest kernel.
Alternative solution – tested on ArcoLinuxB Openbox
Edit /etc/pacman.conf and add this line
IgnorePkg = linux virtualbox-guest-modules-arch
And then do your updates.
