The instructions on this page may require deviations from standard procedures. A good understanding of linux and Koozali SME Server is recommended.

This how to is *out of date* and refers to SME7. You probably need to install smeserver-phpvirtualbox and smeserver-virtualbox contribs for Koozali SME10 : Phpvirtualbox

Description

This contribution for smeserver adds Sun VirtualBox 3.0.10 for Headless operation (ie creates a virtual machine on your server that can be access via an RDP client such as 'Remote Desktop Connection' on Windows. This allows you to have a virtual Windows machine running at a remote location to perform various administrative tasks. You can run network applications as if you were in the remote office and will not tying up a physical machine.

For instruction on how to install VirtualBox 4.0 on SME Server v8 beta 6, check this wiki page.

Requirements

You will need SME Server 7.4, kernel 2.6.9-78.0.22.EL or 2.6.9-78.0.22.ELsmp check your current kernel using 

uname -r

You will also need to download the VirtualBox rpm file 

wget http://download.virtualbox.org/virtualbox/3.0.10/VirtualBox-3.0.10_54097_rhel4-1.i386.rpm

You will also need the precompiled kernel modules

For 2.6.9-78.0.22.EL 

wget http://kevinps2003.tripod.com/VirtualBox3.0.10_Modules_2.6.9-78.EL.tar.gz

For 2.6.9-78.0.22.ELsmp 

wget http://kevinps2003.tripod.com/VirtualBox3.0.10_Modules_2.6.9-78.ELsmp.tar.gz

Installation

1. Download the files to your folder on your server (it is a good idea to keep these file around if you ever need to rebuild a server)

2. Install the dependencies for VirtualBox (this will install the alsa-lib and SDL) 

yum install SDL

You may need to run the following commands to complete the installation 

signal-event post-upgrade
signal-event reboot

3. Create a new group ‘vboxusers’ in the server manager and assign the appropriate users.

4. Create a new ibay for the VirtualBox settings and hard drive files. Set the Group to ‘vboxusers’ and User Access to ‘read=group, write=group’.

5. Install VirtualBox using the following command 

rpm -Uvh VirtualBox-3.0.10_54097_rhel4-1.i386.rpm

Note - You will get the following error message, which you can ignore, we will manually copy and install the precompiled modules 

Creating group 'vboxusers'. VM users must be member of that group!

No precompiled module for this kernel found -- trying to build one. Messages
emitted during module compilation will be logged to /var/log/vbox-install.log. 

Compilation of the kernel module FAILED! VirtualBox will not start until this
problem is fixed. Please consult /var/log/vbox-install.log to find out why the
kernel module does not compile. Most probably the kernel sources are not found.
Install them and execute

  /etc/init.d/vboxdrv setup

as root.

6. Extract files from VirtualBox3.0.10_Modules_2.6.9-78.EL*.tar.gz 

tar -zxvf VirtualBox3.0.10_Modules_2.6.9-78.EL*.tar.gz

7. Copy precompiled VirtualBox drivers to the appropriate lib/modules/… folder

For 2.6.9-78.0.22.EL 

cp vboxdrv.ko /lib/modules/2.6.9-78.0.22.EL/
cp vboxnetflt.ko /lib/modules/2.6.9-78.0.22.EL/
cp vboxnetadp.ko /lib/modules/2.6.9-78.0.22.EL/

For 2.6.9-78.0.22.ELsmp 

cp vboxdrv.ko /lib/modules/2.6.9-78.0.22.ELsmp/
cp vboxnetflt.ko /lib/modules/2.6.9-78.0.22.ELsmp/
cp vboxnetadp.ko /lib/modules/2.6.9-78.0.22.ELsmp/

8. Change module permissions and owner using the following commands (this step might not be required)

For 2.6.9-78.0.22.EL 

chown root:root /lib/modules/2.6.9-78.0.22.EL/vboxdrv.ko

Note - if you have get a few lines containing the following 

WARNING: Can't read module /lib/modules/2.6.9-78.0.22.EL

You will need to update your server (See comment #6, Bug #5334, not recommended for a production server), or manually edit the modules.dep file.

For 2.6.9-78.0.22.EL 

pico /lib/modules/2.6.9-78.0.22.EL/modules.dep

Add the following lines 

/lib/modules/2.6.9-78.0.22.EL/vboxdrv.ko:
/lib/modules/2.6.9-78.0.22.EL/vboxnetadp.ko:
/lib/modules/2.6.9-78.0.22.EL/vboxnetflt.ko: /lib/modules/2.6.9-78.0.22.EL/vboxdrv.ko

For 2.6.9-78.0.22.ELsmp 

pico /lib/modules/2.6.9-78.0.22.ELsmp/modules.dep

Add the following lines 

/lib/modules/2.6.9-78.0.22.ELsmp/vboxdrv.ko:
/lib/modules/2.6.9-78.0.22.ELsmp/vboxnetadp.ko:
/lib/modules/2.6.9-78.0.22.ELsmp/vboxnetflt.ko: /lib/modules/2.6.9-78.0.22.ELsmp/vboxdrv.ko

13. Test that the kernel modules load properly with the following command 

modprobe vboxnetflt
modprobe vboxnetadp

14. Verify the kernel modules are loaded 

lsmod | grep vbox

Should result in 

vboxnetadp             73576  0
vboxnetflt             80776  0
vboxdrv               106920  1 vboxnetflt

15. Create/edit the /etc/rc.modules file to load vboxdrv and vboxnetflt at boot time 

pico /etc/rc.modules

Add the following lines and save 

modprobe vboxnetflt 
modprobe vboxnetadp

Run the following command to make the script executable. 

chmod +x /etc/rc.modules

16. Remove the file that flags vboxdrv and vboxnetflt module as not being installed properly 

rm /etc/vbox/module_not_compiled

17. Set Environment Variable (replace 'vbox_files' with the ibay you created) 

export VBOX_USER_HOME=/home/e-smith/files/ibays/vbox_files/files/.VirtualBox

18. Permanently set Environment Variable 

pico /etc/profile.d/vboxpath.sh

Add the two lines below (replace 'vbox_files' with the ibay you created) 

# /etc/profile.d/vboxpath.sh - Set Virtual Box Settings Location
export VBOX_USER_HOME=/home/e-smith/files/ibays/vbox_files/files/.VirtualBox

Change the permissions on the script to make it executable 

chmod 755 /etc/profile.d/vboxpath.sh

19. Verify the environment variable is set 

echo $VBOX_USER_HOME

Should result in (where 'vbox_files' is the ibay you created) 

/home/e-smith/files/ibays/vbox_files/files/.VirtualBox

20. You can now create and run your own virtual machines using VBoxManage and VBoxHeadless (located in /usr/bin/).

Usage - VBoxManage

To create a virtual machine, use the following command, replace "WinXP" with the name of your new virtual machine. 

VBoxManage createvm -name "WinXP" –register

Set the amount of RAM for your virtual machine 

VBoxManage modifyvm "WinXP" -memory "128MB"

When modifying your virtual machine, you will need to pay close attention to the amount of physical ram in your server. Use the following command to check the amount of free memory in your server 

free -m

Enables 'ACPI' for your virtual machine in VirtualBox 

VBoxManage modifyvm "WinXP" -acpi on

Creates a new virtual hard disk file (VDI). Note, size is in MB. The file will be saved to /home/e-smith/files/ibays/vbox_files/files/.VirtualBox/HardDisks/WinXP.vdi 

VBoxManage createvdi -filename "WinXP.vdi" -size 20000 -register

Assign the hard disk file to your new virtual machine 

VBoxManage modifyvm "WinXP" -hda "WinXP.vdi"

Sets the first boot device for your virtual machine to dvd (ie installing OS) 

VBoxManage modifyvm "WinXP" -boot1 dvd

Adds a CD/DVD image (located on your server) to VirtualBox media manager (note, replace the path below with the path to your installation media) 

VBoxManage registerimage dvd /home/e-smith/files/ibays/iso_images/files/WinXP.iso

Assigns the CD/DVD image to your virtual machine 

VBoxManage modifyvm "WinXP" -dvd /home/e-smith/files/ibays/iso_images/files/WinXP.iso

Remove the CD/DVD image from your virtual machine 

VBoxManage modifyvm "WinXP" -dvd none

Sets the Virtual NIC to the VirtualBox 'nat' (can't communicate with other computers on lan, but has internet access via your server) 

VBoxManage modifyvm "WinXP" -nic1 nat

To give your virtual machine an IP Address from your local network (ie DHCP provided by another machine), use the following commands to change the Virtual NIC to use your LAN connection. If your server is configured as a gateway, make sure that 'eth0' is the LAN port not the WAN otherwise your virtual machine will be exposed to the internet without a firewall. 

VBoxManage modifyvm "WinXP" -nic1 bridged
VBoxManage modifyvm "WinXP" -bridgeadapter1 eth0

The commands above were based on this guide. [1]

Usage - VBoxHeadless

To start your virtual machine use the following command 

VBoxHeadless -s "WinXP"

To access your virtual machine, you will need to connect via an RDP client. On Windows you can use the built in 'Remote Desktop Connection' to access your virtual machine. Open your RDP client and input the IP address/Name of your SME Server into the box and press Connect.

RDP Connection.jpg

Note there is no authentication when connecting by default, consult the VirtualBox documentation for instructions on implementing authentication.

To start your virtual machine on a different port (ie 12345), use the following command 

VBoxHeadless -s "WinXP" -p 12345

Then enter 'IPaddress:port' into your RDP client. For Windows Remote Desktop Connection use 

192.168.1.1:12345

Uninstall
