Upgrading Linux Guests

Just last week Oracle released Oracle Linux 6.4 and so it was time that Fat Bloke updated his Oracle Linux guests.

So after a simple and quick:

 yum update

I was in a position to reboot into my freshly updated 6.4 vm. But after rebooting I found myself looking at a stuck screen that looked a little like this:

The reason for getting stuck like this was because the installed VirtualBox Guest Additions were configured for an older X11 server, and the new update had a newer version.

So here's how to fix this:

1. At this screen, type Ctrl-Alt-F2 to get to another virtual display;
2. login, and as root type: 

/etc/init.d/vboxadd-x11 setup 

like this:

3. reboot
4. et, voila!

Hope this helps,
