+Installing Guest Additions in run-level 3 on CENTOS6 and CENTOS7:
+  * https://linuxconfig.org/how-to-mount-cdrom-in-linux
+  * First, go to the VirtualBox window that is running the guest machine and choose Devices > Insert Guest Additions CD Image
+  * From a separate terminal window (via ssh) or in the VM window itself, su - root
+  * yum install cdrecord
+  * wodim --devices
+    * (note the drive designation)
+      * If that command fails on a CENTOS7 v7.2.1511 VirtualBox instance, try: wodim dev=/dev/sr0 --devices
+      * If that succeeds, it should say something like 'VBOX'  'CD-ROM'
+      * Or: wodim -prcap (although that doesn't seem to give you the info needed)
+      * See [[https://bugs.launchpad.net/ubuntu/+source/cdrkit/+bug/1203559]]
+  * mkdir /media/cdrom
+  * mount -t iso9660 /dev/scd0 /media/cdrom
+    * if you used "sr0" above, substitute sr0 for scd0 in the line above
+  * cd /media/cdrom
+  * Then run Linux version of script
+    * Ex: sh VBoxLinuxAdditions.run
+  * When done, cd / and eject and reboot
