Are you using the 5.2.23 test version of VirtualBox?  5.2.22 won't work, 
as mentioned in the release notes at 
https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7.1810

"If you use VirtualBox to run CentOS 7.6.1810 as a guest with a GUI, you 
need version 5.2.23 to build graphics drivers. See VBox ticket 18093 
<https://www.virtualbox.org/ticket/18093>. Also, the mouse may not work 
properly as reported in this VBox forum thread 
<https://forums.virtualbox.org/viewtopic.php?f=3&t=90267>."
