Updated October 2016 for wodim issues
Installing Guest Additions in run-level 3 on CENTOS6 and CENTOS7:
- 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)
- 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
