This sets up and starts a couple OpenBSD carped virtual machines using qemu and flashrd.
#!/bin/sh
# This uses qemu, so pkg_add qemu
# Download and extract flashrd, either from github or here:
# http://www.nmedia.net/flashrd/
# Grab a flashrd image from here:
# http://www.nmedia.net/flashrd/images/
# and set the name:
flashimg=flashimg.amd64.pccons-20130318
# Set a path where you have space to copy the images
test_path=`mktemp -d`
# And setup the path where we can find cfgflashrd
flashrd_root=$PWD
cd $test_path
### XXX NOTE XXX ###
# This is going to remove ./test in $test_path
