There are known issues with VirtualBox and RHEL (therefore CentOS) 7.6.

(1) is about the GuestAdditions, so this should not affect the
installation. But you were most likely hit by (2). All the details are
in that forum thread. In short, this is caused by a bug in the 7.6
kernel (see also https://bugs.centos.org/view.php?id=15570 ). It is
possible that the next update to the kernel has the fix but this
remains to be seen.
