Solaris Cluster in a Box

A VirtualBox Solaris Cluster complete with shared storage and quorum disk!

Host System

The host system is a Mac running 10.8:

Intel Core i7-3770K Ivy Bridge 3.5GHz
16Gb RAM
GeForce GTX 470 1280M
At the time of this article, I’m running Mac OSX 10.8.2 with VirtualBox 4.2.6. The Solaris Cluster is 3.3 running in a Solaris 10u10 virtual machine.

VirtualBox Serial Port Console on Solaris 10

If you’re like me and prefer the command line to the GUI, here’s a trick and script to help you manage your Solaris VMs.

  1. Enable a serial port for the VM.
    1. Enable Port 1
    2. Port Number COM1
    3. Port Mode: Host Pipe
    4. Create Pipe
    5. Port/File Path: /tmp/vb-VM-NAME-console
  2. Perform a reconfiguration boot on the VM.
  3. Install socat on the host system

    sudo apt-get install socat
  4. Change the eeprom console device for the VM:

    eeprom console=ttya
  5. Change the /boot/grub/menu.lst for the VM:

    ...
    # To enable grub serial console to ttya uncomment the following lines
    # and comment out the splashimage line below
    # WARNING: don't enable grub serial console when BIOS console serial
    #       redirection is active!!!
    serial --unit=0 --speed=9600
    terminal serial
    #
    # Uncomment the following line to enable GRUB splashimage on console
    #splashimage /boot/grub/splash.xpm.gz
    #
    # To chainload another OS
    ...
  6. Bring down the VM:

    init 5
  7. Once this is done, we can now tell VirtualBox to boot the VM headless and connect with socat

    VBoxManage startvm node1 --type headless && socat -,raw,echo=0 /tmp/vb-node1-console

    I wrote a perl script to handle booting and connecting the console. Feel free to download: vb.pl


    $ vb.pl -h
    usage:

    vb.pl -l
    vb.pl -n VM -b
    vb.pl -n VM -p
    vb.pl -h

    -l : list VirtualBox machines
    -n : name of the VirtualBox machine
    -b : power on and boot machine
    -p : power off machine
    -h : this message.
