# Variable explanations:
# VMMachine = Friendly name of virtual machine
# VMDir = Directory path of Virtual Machine
# VMFile = Virtual Machine Configuration File (.vmx file)
# VMDisplay = Virtual Machine Display (start with 1)
# VMTerminal = Virtual Machine Terminal to use (start with 8)
# VMDns = DNS name assigned to the Virtual Machine
# VMShutdownTimer = Time to wait for VM shutdown (in seconds)
# 5 Minutes is normally more than adequate
#
# Each virtual machine must have its own X display and terminal. 
# Assuming a standard installation that runs X on display 0 and 
# vt7, your first virtual machine will use:
# X display 1 and vt 8
# The second:
# X Display 2 and vt 9
# and so on.

# Set this to what you need
