CentOS Installation VirtualBox

My CentOS version is:

#cat/etc/issue:

CentOS Release 6.2 (Final)

1. Install the associated package

Yum install kernel-headers kernel-devel gcc make

2. View the downloaded kernel code version

ls/usr/src/kernels/

2.6.32-279.14.1.el6.i686

3. View the kernel version of this machine

Uname-r
2.6.32-220.2.1.el6.i686

4. The above 2 versions must be consistent, otherwise there will be a problem, yum install kernel-headers installed should be the latest version, use the following command to upgrade the native kernel to the current version:

Yum Upgrade kernel

After kernel upgrade reboot, check the native kernel again:

Uname-r
2.6.32-279.14.1.el6.i686

5. Start the installation of VB

[Root@linux]# cd/etc/yum.repos.d/
[Root@linux]# wget Http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
[Root@linux]# Yum Install VirtualBox-4.2

6. Assigning a user to a VB group

/usr/sbin/usermod-a-G vboxusers Root

7. Start VirtualBox [Root@linux] #virtualbox
