Centos7 kernel downgrade failure 7.6 to 7.5
Re: Centos7 kernel downgrade failure 7.6 to 7.5
And what errors do you have now in your logs?
The future appears to be RHEL or Debian. I think I'm going Debian.

Re: Centos7 kernel downgrade failure 7.6 to 7.5
I only got a chance to look at Xorg on /var/log/.
The same complaint/error appeared:
An suggestion about other diagnostics to run or logs to look at?

Re: Centos7 kernel downgrade failure 7.6 to 7.5
Hmm, and you rebuilt the Guest Additions on that same kernel? I believe it writes a log to /var/log when you build it, did you check that to makre sure it worked properly?

Yes, rebuild GA for old kernel. I will check that log and post back.

In the vboxadd-setup.log only this message:
This same message shows on terminal screen during GuestAdditions re-install as well.

Update
Launching the X server from the terminal (always in recovery mode, aka Ctl+Alt+F2) via:
Gets me beyond the black screen into log-ing mode.
In /var/log/Xorg.0.log all of the following errors are present, BUT the server doesn't crash.
Are these VirtualBox related issues?
Note: GuestAdditions un-installed and re-installed again without errors; except for the message posted previously.

Re: Centos7 kernel downgrade failure 7.6 to 7.5
vboxvideo is the video driver that is built by installing the Guest Additions. If it doesn't exist then it means the build failed so the next point of call is the build log file. Post it if you don't understand it.

Re: Centos7 kernel downgrade failure 7.6 to 7.5
In /var/log/vboxadd-install.log
The following resolved it for me. Warning: this may not work for all situations nor is a sound solution.
1. Edited grub menu to log-in with selinux=0.
- Gnome, X-server, network connectivity were all functional
- This confirmed: related to SElinux policies. What happened exactly, context relabeling messed-up (?)
2. Reinstalled GuestAdditions. Uninstall
script/folder were absent under /opt. GA install successful but log showed one error related to SElinux.
3. $ shutdown then booted again like in 1.
4. Changed SElinux policy to 'disabled'.
Thanks so much @TrevorH.
