Don't forget to configure the yum-priorities plugin. Installing DKMS from the EPEL repository is recommended before installing VirtualBox. If DKMS (Dynamic Kernel Module Support) is installed it will be used and will simplify kernel upgrades.

The installation of VB will require the building of kernel modules. Login to a root shell or 'su -' in a terminal window. You will need to be the root user for the following tasks. After the install reboot and perform firstboot configuration. Start the VM and perform a graphical install, or if desired a text install.

For a first install attempt make a minimum of changes to the defaults. Change any additional settings, such as the amount of memory for the virtual video adapter, and whether to use NAT or Bridged networking. Navigate to the directory where the ISO image reside and pick one, for example CentOS-6.7-x86_64-LiveDVD.iso or CentOS-7-x86_6.iso. Additional disk can be added later if desired.Īfter the VM is created, run Settings, go to Storage, and under IDE Controller click on the CD icon on the left, then select the similar CD icon on the right and pick Choose a virtual CD/DVD from the list. For a relatively full install, allocate at least 15GB, otherwise use all the defaults. Next the virtual hard disk wizard will start.

Memory should be at least 768MB for a graphical install to work. Start by downloading the ISO file you wish to use for installation from a CentOS Mirror.Ĭreate a New Virtual Machine (VM) with the Virtual Machine Wizard, choosing Linux for the OS Type and Red Hat or Red Hat (64 bit) for the Operating System. Installation of CentOS as a guest OS is much like installing on real hardware.
