CentOS guest fails to completely boot

Reported by: S.Torri Owned by:

I have CentOS 6.5 guest OS running in a VM on Windows 7 Professional host OS. The problem I am having is that the CentOS starts to boot showing its tri-color progress bars but fails to completely boot once they reach 100%. The screen shows the load screen with the progress bar greyed out with the words "CentOS 6.5" to the right of it. I have had other guest OS freeze like this before. My only recourse was to reinstall the guest OS. Is there a way to check or fix a guest image to see what is wrong?

Something is happening with the Xorg configuration file that is causing the boot to hang. To get around this problem boot the guest Linux OS in single user mode:

1. Start guest OS
2. When GRUB message comes on the screen press `Esc`
3. Type 'a' to append the word "single" to the end of the kernel statement
4. Press enter

At the 'root' prompt remove/rename Xorg configuration file:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bk

Reboot the system.

Removal of the /etc/X11/xorg.conf allowed the system to reboot. I think because I installed NVIDIA CUDA there was an additional configuration file in the /etc/X11/yum.conf.d directory from NVIDIA that was messing with the default Xorg configuration. Something in those files or the drivers were preventing the X windows to start.
