Is it?  I refer to this part of vmrun.sh:

	file -s ${first_diskdev} | grep "boot sector" > /dev/null
	rc=$?
	if [ $rc -ne 0 ]; then
		file -s ${first_diskdev} | grep ": Unix Fast File sys" > /dev/null
		rc=$?
	fi
	if [ $rc -ne 0 ]; then
		need_install=1
	else
		need_install=0
	fi

Which is not expected to be particularly robust.
(BTW, I think there is not agreement as to whether vmrun.sh should
be used in general use, or alternate solutions for VM managemnet.)
