Follow the provided installation instructions in the manual.
Note: Just because the host machine is 64-bit does not mean the VirtualBox will run a guest 64-bit machine. Processor limits of the host machine seem to be the culprit or certain manufacturer's chips seem to be the limit.
Machine took power hit and UPS failed. VirtualBox application would start, but no virtual machines would start. Kernel error. Had to remove VirtualBox and reinstall the same version (VirtualBox-5.0-5.0.10_104061_el6-1.x86_64.rpm)
1) Building the OpenGL support module [ FAILED ]
1) VirtualBox 5.0 mini toolbar does not work correctly in full screen
1) Boot error message: (modprobe vboxdrv failed. Please use 'dmesg' to find out why)
Install the dkms rpm package. It can slow the time to perform updates but it will stop this error message and also allow VirtualBox to work with new kernels seamlessly.
1) Upgrading to VirtualBox-4.3-4.3.4_91027_el6-1.x86_64.rpm causes failures when trying to start the VMs
Need to go into BIOS and under security options allow VirtualMachines to run.
2) Error message:

OpenGL support fails when installing Guest Additions on VirtualBox 4.2.10 r84104
Mount the Guest Additions CD .iso (Devices> Install Guest Additions…)
Open terminal as root:
# export MAKE='/usr/bin/gmake -i' # cd /media/VBOXADDITIONS_4.2.10_84104 # sh VBoxLinuxAdditions.run
No X Display CENTOS 6.4
Need to investigate. Problem exists with VirtualBox 4.2.8 r83876
Appears that removing /etc/X11/xorg.conf (save to a backup file) and letting the system rebuild xorg.conf allows VirtualBox to come again into graphical X Windows.
Crashes and won't boot
Crashes immediately upon boot on Dell E510 hardware. Add "edd=off" to kernel boot parameter.
Crashes and won't boot
Chipset problems cropped up for later kernels in Centos6.2…kernel panic upon booting. Fix is:
Change chipset settings in the VirtualBox Manager from PIIX3 to ICH9. Turn on IO APIC. Reboot guest CentOS.
The default settings under System > Motherboard was Chipset PIIX3, unchecked enable IO APIC
To migrate a VM install from other piece of hardware, just rsync ~/.VirtualBox and the location of the Virtual Box machine (default is ~/VirtualBox VMs)
When updating kernel on VM, you need to re-install guest additions and restart guest OS to get the seamless view/auto resize mode again.
Install the "VirtualBox Guest Additions" add-on to the Virtual Box Manager. Then login to the guest system and double-click the desktop icon for Additions. This package will enable proper screen resolution, mouse behavior, etc.
Change the guest OS to a higher display resolution and maximize the guest VM display window
Change theme if desired (under System > Preferences > Appearance > Themes)
Change mouse pointer to white (under System > Preferences > Appearance > Themes > Customize)
Change the system fonts to 8 point (System > Preferences > Appearance > Themes) and under the Advanced tab change the DPI resolution from the default (98) to 96.
Set up .bashrc
Set up gnome-terminal to monospace 9pt, unlimited text scrollback, blinking cursor if available
If desired, install webcore-fonts-1.3-1 (and see if Monospace 9pt fonts looks any different)
Adobe Reader is not installed in default channel - see CentOS Additional resource page at http://wiki.centos.org/AdditionalResources/Repositories and look for the Adobe Repository
Install Adobe flash (download rpm from Adobe website)
Install work's VPN software. Likely need to do a 'yum install libxml2.i686' first, though.
KRDC on CentOS6 guest OS: the width needs to be about 6 pixels less than current screen resolution to avoid the end scrollbars. Be sure to use FQDN.
KRDC on CentOS5 host OS: works fine; appears to make rdp:/hostname.domain.com by default a VNC connection which doesn't have odd black cursor/mouse.
Issues with CentOS6 installed under VirtualBox:
Old note for after new kernel install…..do this as root:
