create-smartos-vm.sh

#!/bin/sh
#
# Creates a SmartOS VM in VirtualBox (assuming you alread have VirtualBox installed)
#
# This script will:
#   * Download the latest live ISO image of SmartOS
#   * Create a VirtualBox VM, or update an existing VM with the latest ISO
#   * Configure the VM with a zones disk, and boot it!
#
#
# To create a node.js vm see: http://GIST
#
#
# Original script from Jonathan Perkin:
#   http://www.perkin.org.uk/posts/automated-virtualbox-smartos-installs.html
#
#
# Changes (to original script):
# * Use md5 or md5sum command (whichever exists)
# * Use bridged networking (instead of NAT) w/prompt for network device
# * Promiscuous mode (Allow-all) for direct access to/from SmartOS VMs
