Description

Below are instructions on how to install VirtualBox version 4 on a fresh install SME Server v8 beta 6 and higher. Plus installing and configuring phpVirtualBox to control (create, edit, remove) your virtual machine on its web interface. In addition, scripts to automatically start the vbox service and the virtual machines in case of power failure can be found at the end of this article.

Requirements

Computer with SME server version 8 beta 6 and higher installed.

Installation

1. Setup SME Server v8 beta 6.
2. Do a yum update.

yum update

3. If any updates were applied, update and reboot the server.

signal-event post-upgrade
signal-event reboot

4. Check your current kernel.

uname -r

5. Install kernel-devel to get the latest development tree.
Use this command only if you have a PAE kernel installed:

yum install kernel-PAE-devel kernel-headers

Otherwise,

yum install kernel-devel kernel-headers

6. Check if the compiler (GCC) is installed. If not installed, install it.

yum install gcc

7. Update SME, and reboot again

signal-event post-upgrade
signal-event reboot

8. Create a symbolic link

NOTE: Be careful if you cut-and-paste the command below.
In some terminal windows, from some browsers, the parts of the command in
bold font do not paste correctly. Pay particular attention to the
dashes (-) and the backticks (`). There aren't any single quote marks in
the command below - they are all supposed to be backticks.

ln –s /usr/src/kernels/`uname –r`-`uname-m` /lib/modules/`uname -r`/build

9. Check that the symbolic link was properly created by doing a directory listing.

NOTE: Be careful if you cut-and-paste the command below.

ls /lib/modules/`uname -r`/build

10. Install the Fedora Epel repository using the instructions here.
11. Install Dynamic Kernel Module Support (DKMS)

yum install --enablerepo=epel dkms

12. Install the VirtualBox repository using the instructions here.
13. Install VirtualBox (At the time of the last update to these instructions, the latest version was v4.1-2).

yum install --enablerepo=virtualbox VirtualBox-4.1

14. Review the VirtualBox installation log to ensure that the installation was successful.

tail /var/log/vbox-install.log

15. Remove the compiler install (for security best practices)

 rpm -e gcc

16. Update SME, and reboot again

signal-event post-upgrade
signal-event reboot

17. Setup VirtualBox as a service so it starts automatically after a reboot.

cp /etc/rc5.d/S30vboxdrv /etc/rc7.d/.
cp /etc/rc5.d/S35vboxballoonctrl-service /etc/rc7.d/.
cp /etc/rc5.d/S35vboxweb-service /etc/rc7.d/.

18. Create a vbox.cfg file on your /etc/vbox/.

nano /etc/vbox/vbox.cfg

vbox.cfg should have this content.

VBOXWEB_USER='root'
VBOXWEB_HOST=127.0.0.1
VBOXWEB_PORT=18083

Note: Without the vbox.cfg, vbox services on your rc7.d folder will not start.

19. Login to the server-manager page and create an ibay for phpvbox. For instructions on how to create and configure an ibay, please see the SME Server Administration manual.
After creating the ibay, do not forget to assign a password.
20. Before we install phpVirtualBox, make sure you install SOAP first

yum install php-soap

21. Install phpVirtualBox

cd /tmp
wget `wget -q -O - http://phpvirtualbox.googlecode.com/files/LATEST.txt` -O phpvirtualbox-latest.zip
unzip phpvirtualbox-latest.zip

Note: at the time of the last update, the latest version was 4.1-2. Please adjust the following for later versions.

cd phpvirtualbox-4.1-2
cp –R * /home/e-smith/files/ibays/phpvbox/html

22. Create a tmp folder inside the /phpvbox/html folder.

cd /home/e-smith/files/ibays/phpvbox/html
mkdir tmp
chmod 777 tmp/

23. Create a config file using the example file provided.

cp config.php-example config.php

24. Open config.php (located on your /phpvbox/html/ folder). Uncomment some lines (by removing the '#' at the beginning of the line).

nano /home/e-smith/files/ibays/phpvbox/html/config.php

/* SOAP URL of vboxwebsrv (not phpVirtualBox's URL) */
var $location = 'http://127.0.0.1:18083/';

// Disable authentication
var $noAuth = true;

Adjust the consoleHost ip address to an unused static ip address on your internal network

// Host / ip to use for console connections
//var $consoleHost = '192.168.100.1';

/* Enable advanced configuration items (normally hidden in the VirtualBox GUI)
 * Note that some of these items may not be translated to languages other than $
 */
var $enableAdvancedConfig = true;

// Authentication library.
//var $authLib = 'Builtin';

// Allow VDE network configuration. This must be supported by the underlying VirtualBox installation!
var $enableVDE = true;

Change the tmp location as per below.

// Path
var $cachePath = '../tmp';

25. Disable authentication of vboxwebsrv (this is not recommended, but at this stage, this is the only setup that works). Login to the server’s SSH and type this command.

vboxmanage setproperty websrvauthlibrary null

26. Install VirtualBox extension pack to enable support for USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards. Please install the extension pack with the same version as your installed version of VirtualBox!
You can find the extension packs here. The following commands download and install the extension pack for VirtualBox 4.1.2.

wget http://download.virtualbox.org/virtualbox/4.1.2/Oracle_VM_VirtualBox_Extension_Pack-4.1.2-73507.vbox-extpack
vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.1.2-73507.vbox-extpack

27. Enable fopen on php.ini (line 65) located on /etc/

allow_url_fopen = On




28. Go to http://your_server’s_ip/phpvbox (e.g. http://192.168.100.1/phpvbox) to create our virtual machine.
    • Create a new virtual machine (e.g. vmXP)
    • Enable network card (either NAT or Bridged) so you can connect to your new VM console.
    • Open an RDP client (run->mstsc) then type your server’s IP address e.g. 192.168.100.1.

    

29. Download VirtualBox Guest Addition from here http://download.virtualbox.org/virtualbox/4.0.8/VBoxGuestAdditions_4.0.8.iso and install it to your newly setup VM.

Automatically Start Virtual Machine

1. Edit your vbox file on /etc/sysconfig/

nano /etc/sysconfig/vbox

vbox code should look like this:

# Virtual box machines to autostart
# Example to start 2 machines
#       VBOX_AUTOSTART = "MachineName1 MachineName2"

VBOX_AUTOSTART="vmXP"

2. Edit your vbox file located on /etc/init.d/

#!/bin/sh
#
# chkconfig: - 91 35
# description: Starts and stops vbox autostart VMs.
