Call setting:

QEMU_MEMORY (optional) - set the amount of memory in the emualted system.

SERIAL_LOGFILE (optional) - log the serial port output to a file

CROSSPATH - the path to any cross toolchain to use with distcc

Image options:

MACHINE - the machine to run

TYPE - the image type to run

ZIMAGE - the kernel image file to use

HDIMAGE - the disk image file to use
