Description

Below are instructions on how to install VirtualBox version 4.1 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.

This has been tested using the following:

  1. SME Server Release 8.0
  2. VirtualBox-4.3
  3. Kernel is 2.6.18-348.6.1.el5

Requirements

Computer with SME server version 8 and higher installed.

Installation

  1. Setup SME Server v8.
  2. Do a yum update.
  3. yum upgrade
  4. If any updates were applied, update and reboot the server.
  5. signal-event post-upgrade; signal-event reboot
  6. Check your current kernel.
  7. uname -r
  8. Install kernel-devel to get the latest development tree.
    Use the command below, only if you have a PAE kernel installed:
    yum clean all
    yum install kernel-PAE-devel kernel-headers
    yum info kernel-headers

    Otherwise,

    yum install kernel-devel kernel-headers
  9. Note : if you do not want to update your kernel, because of kmdl not available you can search for the right kernel-headers and kernel-devel in http://vault.centos.org/
  10. Check if the compiler (GCC) is installed by issuing this command.
    rpm -qa | grep gcc

    You will have an output, similar to this:

    libgcc-4.1.2-54.el5
    gcc-4.1.2-54.el5

    If not installed, install it.

    yum install gcc

    If you will get an error "No package gcc available. Nothing to do" then do this:

    cd /tmp
    wget ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/gcc-4.7.1/gcc-4.7.1.tar.gz
  11. Update SME, and reboot again.
  12. signal-event post-upgrade; signal-event reboot
  13. Change your kernel boot options.
    Optionally, for best results with SME 8.x and earlier versions, modify /etc/grub.conf, adding divider=10 to the kernel boot options in order to reduce the idle CPU load with VirtualBox. For example, if your kernel boot line is:
    kernel /vmlinuz-2.6.18-348.6.1.el5 ro root=/dev/main/root 

    change it to:

    kernel /vmlinuz-2.6.18-348.6.1.el5 ro root=/dev/main/root divider=10

    Reminder: if you subsequently update SME Server to use a newer kernel, you may need to change your kernel boot line to reflect the update.

  14. Create a symbolic link.

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

    Reminder: if you subsequently update SME Server to use a newer kernel, you may need to recreate the symbolic link.

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

    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.

    ls -la /lib/modules/`uname -r`/build
  16. Install the Fedora Epel repository using the instructions here.
  17. Install Dynamic Kernel Module Support (DKMS)
  18. yum install --enablerepo=epel dkms
  19. Install the VirtualBox repository using the instructions here.
  20. Install VirtualBox (At the time of the last update to these instructions, the latest version was v4.3-4.3.6-91406).
  21. yum install --enablerepo=virtualbox VirtualBox-4.3
  22. Review the VirtualBox installation log to ensure that the installation was successful.
  23. tail /var/log/vbox-install.log
  24. Remove the compiler install (for security best practices)
  25. rpm -e gcc
  26. Update SME, and reboot again
  27. signal-event post-upgrade; signal-event reboot
  28. Setup VirtualBox as a service so it starts automatically after a reboot. Copy the command below on putty console then hit Enter.
  29. for file in $(ls /etc/rc5.d/S??vbox*); do cp "$file" /etc/rc7.d/. ;done
  30. Create a virtualbox file on your /etc/default/.
  31. nano /etc/default/virtualbox

    virtualbox should have this content.

    VBOXWEB_USER='root'
    VBOXWEB_HOST=127.0.0.1
    VBOXWEB_PORT=18083
    VBOXWEB_LOGFILE=/var/log/vboxweb
    INSTALL_DIR=/usr/lib/virtualbox

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

  32. Install phpVirtualBox using this link http://wiki.contribs.org/Phpvirtualbox#DB_Configuration
  33. Ensure that the extension pack is installed correctly. Open a console window, then
    vboxmanage list extpacks
  34. At this point, VirtualBox should now be configured and running correctly. To check this, we will now log into the ibay we created for phpVirtualBox and attempt to create a new virtual machine. If you encounter problems, please recheck that you have setup VirtualBox as a service so it starts automatically after a reboot, and that your vbox.cfg file is configured correctly. To manage VirtualBox and any virtual machines, use the command line utility VBoxManage. See VBoxManage --help . For a list of available switches for VBoxManage, see this list. Finally,
  35. Open a terminal window to the SME Server and create a directory to store the virtual machine images.
  36. mkdir -p /root/VirtualBox VMs/addons
  37. Download the VirtualBox Guest Additions iso for later installation into your virtual machine guests.
  38. cd /root/VirtualBox VMs/addons
    wget http://download.virtualbox.org/virtualbox/4.3.6/VBoxGuestAdditions_4.3.6.iso
  39. Using a web browser, Go to http://yourdomain.com/phpvirtualbox and connect to the phpVirtualBox web application. At this point, VirtualBox should now be configured and running correctly. If you encounter problems, please recheck that you have setup VirtualBox as a service so it starts automatically after a reboot, and that your vbox.cfg file is configured correctly. To manage VirtualBox and any virtual machines, use the command line utility VBoxManage. See VBoxManage --help . For a list of available switches for VBoxManage, see this list.

Creating a Virtual Machine

  1. Using a web browser, go to http://yourdomain.com/phpvirtualbox to create your 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.

  2. Even when the extension is installed, the VRDP server is disabled by default. On console:
  3. vboxmanage modifyvm "vmXP" --vrde on
  4. Ensure you are connected to the server's internal network, then open a Remote Desktop client program.
    • On Windows, open an RDP client (run -> mstsc) then type your server’s hostname:port number (e.g. myserver:9000), or your Server's (not your Guest) IP address followed by colon then the port number as shown on above image (Remote Desktop Server Port under Display) (e.g. 192.168.100.1:9000).
    • NOTE: No need to change to port number to 9000 (as per above) in your Windows registry (HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber). It will still be using port 3389 even though phpVirtualBox is using port 9000.
      If you're remotely connected to your server's phpvirtualbox and adding a new Guest remotely, open port 9000 (source and destination TCP poty) pointing to server's IP, so you can be able to access the console built-in to PhpVirtualBox.
  5. Install the VirtualBox Guest Additions ISO into your newly setup VM.
  6. PhpVirtualBox-install-guest-addition.jpg

Access VM outside the Network

  1. On SME Server Manager page, on Port Forwarding left menu, open port 9000 (as per Remote Desktop Server Port under Display) using your desired Source Port:
  2. Protocol: TCP
    Source Ports: 33900
    Destination IP: 192.168.5.1 (which is also the guest IP)
    Destination Port: 9000
    Allow Hosts: <you can leave it blank, or place your Public IP so only your IP can access the VM)
    Rule Comment: <eg. vmXP for SOS>
  3. Now you can access your VM thru RDP using this hostname domain.com:33900

Automatically Start Virtual Machine

  1. Edit your vbox file on /etc/sysconfig/
  2. 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"
    
  3. Edit your vbox file located on /etc/init.d/
    #!/bin/sh
    #
    # chkconfig: - 91 35
    # description: Starts and stops vbox autostart VMs.

    esac
    

Troubleshooting

  1. PhpVirtualBox throws an error attribute does not exist or method 'getVDENetwork' does not exist in the object.

    Solution: Check config.php file located on /home/e-smith/files/ibays/phpvbox/html/ and comment out the line var $enableVDE = true;

  2. #var $enableVDE = true;
  3. Virtual machine with a guest Windows XP installed takes too long to load.

    Solution: The Windows XP disk you might have used is slipstreamed with Intel ICH9 or ICH10. Uninstall iastor.sys on Safe Mode. Once you restart, it will reinstall it for you. Iastor.sys is an Intel Matrix storage manager, used to access RAID drives system driver file.
