# Fact: virtual
#
# Purpose: Determine if the system's hardware is real or virtualised.
#
# Resolution:
# Assumes physical unless proven otherwise.
#
# On Darwin, use the macosx util module to acquire the SPDisplaysDataType,
# from that parse it to see if it's VMWare or Parallels pretending to be the
# display.
#
# On Linux, BSD, Solaris and HPUX:
# Much of the logic here is obscured behind util/virtual.rb, which rather
# than document here, which would encourage drift, just refer to it.
# The Xen tests in here rely on /sys and /proc, and check for the presence and
# contents of files in there.
# If after all the other tests, it's still seen as physical, then it tries to
# parse the output of the "lspci", "dmidecode" and "prtdiag" and parses them
# for obvious signs of being under VMWare or Parallels.
# Finally it checks for the existence of vmware-vmx, which would hint it's
# VMWare.
#
# Caveats:
# Virtualbox detection isn't implemented.
# Many checks rely purely on existence of files.
