how do I install vb 5.2

I also have a how-to that I used to install VirtualBox on ClearOS 6.4

Install VirtualBox 4.3

Get the version of kernel running
uname –a

Linux host.example.com 2.6.32-358.18.1.v6.x86_64 #1 SMP Wed Sep 4 20:58:08 MDT 2013 x86_64 x86_64 x86_64 GNU/Linux

yum --enablerepo=* install gcc wget kernel-headers-2.6.32-358.18.1.v6.x86_64 kernel-devel-2.6.32-358.18.1.v6.x86_64

Install VirtualBox repo
cd /etc/yum.repos.d
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

Install VirtualBox
yum search VirtualBox

This will return the list of VirtualBox versions:

VirtualBox-3.2.i686 : Oracle VM VirtualBox
VirtualBox-4.0.i686 : Oracle VM VirtualBox
VirtualBox-4.1.i686 : Oracle VM VirtualBox
VirtualBox-4.2.i686 : Oracle VM VirtualBox

yum --enablerepo=* install VirtualBox-4.3

Execute the setup of VirtualBox
/etc/init.d/vboxdrv setup

[root@zeus tmp]# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel modules [ OK ]
Removing old VirtualBox pci kernel module [ OK ]
Removing old VirtualBox netadp kernel module [ OK ]
Removing old VirtualBox netflt kernel module [ OK ]
Removing old VirtualBox kernel module [ OK ]
Recompiling VirtualBox kernel modules [ OK ]
Starting VirtualBox kernel modules [ OK ]

Add vbox user to vboxusers group (created by install)
/usr/sbin/useradd -r -m vbox
/usr/sbin/usermod -a -G vboxusers vbox
passwd vbox (set password)

Install VirtualBox Extension Pack
cd /tmp
wget http://download.virtualbox.org/virtualbox/4.3.0/Oracle_VM_VirtualBox_Extension_Pack-4.3.0-89960.vbox-extpack
VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.2.4-81684.vbox-extpack

You could also try installing phpvirtualbox. The web interface is almost exactly like the gui.

Install phpvirtualbox

Create this file
nano /etc/default/virtualbox

Add this to it
VBOXWEB_USER=vbox

Add this entry to the system so it will load vboxweb-service on system startup
chkconfig --level 235 vboxweb-service on
/etc/init.d/vboxweb-service restart

Download phpvirtualbox
cd /tmp
mkdir phpvirtualbox
cd phpvirtualbox
wget http://sourceforge.net/projects/phpvirtualbox/files/phpvirtualbox-4.3.zip
unzip phpvirtualbox-4.3.zip
cd ..
cp –r phpvirtualbox /var/www/html/phpvirtualbox/

Configure phpvirtualbox
cd /var/www/html/phpvirtualbox
cp config.php-example config.php
nano config.php
Change the following lines:
var $username = 'vbox';
var $password = 'password';

Add user to cdrom group (in order to load OS’s from server cdrom)

nano /etc/group

vcsa:x:69:
nscd:x:28:
suva:x:499:
cdrom:x:11:vbox
tape:x:33:
dialout:x:18:
clearsync:x:498:

Run the following to install some dependencies:
yum install php-pear apr php-soap

service httpd restart

Through you web browser go to:
http://host/phpvirtualbox

Default username = admin
Default password = admin

It's humming along nicely now.

Since I couldn't get the ClearOS print server to work properly (see this thread) I've now got a Windows 7 VM running on the server sharing the printer. I also have my DVD ripping software running on it so I can use it for turning DVDs into DivX.

It took me two attempts to get Virtualbox to run on a test machine before I installed it on my production box. There's a howto for Clearos, but it's more than 3 and a half years old, some of the steps don't work, and there are 16 pages in the thread, making it a bit hard to follow. There are various other howtos on the net, all of which leave out some important steps. I reckon I spent a day and a half to get to where it's at now.

I'll post my steps in the existing howto so it's recorded for posterity.

Thanks for the info!

Problem solved :

The first "modifyvm" command needs --nictype1 82540EM added to it so Windows 7 can install native drivers

It also works a lot better if you do the following :
1 - while the VM is powered off, VBoxManage storageattach "Win7" --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium /usr/share/virtualbox/VBoxGuestAdditions.iso
2 - boot up and install the additions from the guest's DVD drive
3 - VBoxManage modifyvm "Win7" --dvd none
