The plan was to install openSUSE Tumbleweed as a VirtualBox guest in an openSUSE Leap 15.1 host with VirtualBox version 6.0.18_SUSE r136238 installed in it. Got the latest openSUSE Tumbleweed Network Image -
RESOLUTION STUCK AT 800x600
Installation was smooth and uneventful. The only issue is that the resolution is
800x600. The Display utility in KDE Plasma 5 lets me change the resolution and it works for a couple of seconds and reverts to
My experience with openSUSE Tumbleweed as a VirtualBox guest has always been good. Not this time. However, before blaming it, I wanted to understand the root cause of the problem.
Looked around on the world wide web and found that the VirtualBox bug tracker has Ticket #19496 already open for the same issue:
The virtualbox 6.1.6 update seems to be okay, but if the matching guest additions is applied to the guest, the auto-resize or resize to any resolution is unavailable. I applied guest additions to several hosts before discovering this issue, including Centos-6, Centos-7, Centos-8, kali linux, and OracleLinux-8. Guests that have not gotten the update seem to be working fine.
VirtualBox Guest Additions from openSUSE repositories
I checked if VirtualBox Guest Additions were installed by default or not:
zypper se --installed-only | grep virtualbox
i | virtualbox-kmp-default | Kernel modules for VirtualBox | package
Surprisingly, found the packages missing. I was expecting them to be present. I installed
virtualbox-guest-x11 and restarted the machine:
sudo zypper in virtualbox-guest-tools virtualbox-guest-x11
Did not work. So, the bug seems to be affecting openSUSE Tumbleweed too. I purged the packages:
sudo zypper rm virtualbox-guest-tools virtualbox-guest-x11
VirtualBox Guest Additions from VirtualBox repositories
On the host running openSUSE Leap 15.1:
VirtualBox UI ->
Insert Guest Additions CD image...
The download began, but failed. Twice. So,:
- Confirmed my VirtualBox version - 6.0.18_SUSE r136238.
- Downlaoded the matching VirtualBox Guest Additions
- Install build tools
sudo zypper in kernel-devel gcc make
- Inserted it into the virtual machine and:
The output was a bit confusing:
Verifying archive integrity... All good.

Even without a restart the resolution was properly set and all was beautiful. I restarted for good measure. All is well.
