After installing RHEL 7 and then attempting to add VirtualBox Guest Additions – the display becomes corrupted and frozen and the instance will not restart. Failed to load SELinux policy

After installing RHEL 7 and then attempting to add VirtualBox Guest Additions – the display becomes corrupted and frozen and the instance will not restart.
Right before the instance attempts to start a messages is displayed as follows:

Failed to load SELinux policy

Only solution I have found to fix this is:

Restart your VirtualBox VM - before it auto boots, press "e"
at the end of the line that starts with "linux16": add selinux=0 (to disable SELinux and allow boot to succeed)
ctrl+x (to save and exit the editor - system will reboot)
Once the server boots, reinstall selinux-policy-targeted as follows:
# yum reinstall selinux-policy-targeted
# touch /.autorelabel
# systemctl reboot

I’ve seen this occur with Oracle Linux 7, Centos 7, RHEL 7 – whether or not Selinux is setup on install.
Another Way To turn off SELinux

sestatus
cd /etc/selinux
vi config 
# change the variable below to:
SELINUX=disabled

Now reboot and rerun the sestatus command
