Haven't had time to follow up on this but I installed an older version of Centos and an older version of Virtual Box and was able to resize my screen with Virtual Box Client. I don't know which did it; I just know it worked.

of course now I am off of Virtual Box and using Docker for my VMs so I won't get to pursue this further.

I'm back to VirtualBox for virtualization on my desktop. I found that with VirtualBox 5.2.8 I am still unable to change the resolution using CentOS build 1708 and Virtual Box Guest Additions. If I go back to CentOS 1511 or 1611 it works fine.

So this issue started with CentOS 1708 for a lot of users and has persisted across multiple versions of VirtualBox. It really does seem like a bug in CentOS perhaps passed down from upstream.

on CentOS 7.5 on VirtualBox 5.2.22 the solution was:

1. install VirtualBox Additions
2. create a kernel module configuration file for the module "vboxvideo". Without the "modeset" parameter the module fails to load.

Code: Select all

echo "options vboxvideo modeset=1" > /etc/modprobe.d/vboxvideo.conf
3. reboot

Also try to upgrade Virtualbox to latest version.

Had same issue because I installed latest CentOS over not so fresh VirtualBox.
And nothing helped me until I upgrade VirtualBox to latest version.

Updating to latest Vbox version seems the solution.
It worked for me as well.
