===== Solaris 10 Serial Console =====

  - Enable a serial port for the VM.
    - Enable Port 1
    - Port Number COM1
    - Port Mode: Host Pipe
    - Create Pipe
    - Port/File Path: /tmp/vb-VM-NAME-console
  - Perform a reconfiguration boot on the VM.
  - Install //socat// on the host system<code>sudo apt-get install socat</code>
  - Change the //eeprom// console device for the VM:<code>eeprom console=ttya</code>
  - Change the ///boot/grub/menu.lst// for the VM:<code>
...
# 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!!!

terminal serial

  - Bring down the VM:<code>init 5</code>
  - Once this is done, we can now tell VirtualBox to boot the VM headless and connect with socat <code>
VBoxManage startvm node1 --type headless && socat -,raw,echo=0 /tmp/vb-node1-console
</code>
