+Step-by-step guide for setting up hostapd/wpa_supplicant test framework (VM)
+----------------------------------------------------------------------------
+
+This document can be used as a quick guide for getting started with
+hostapd/wpa_supplicant test framework with mac80211_hwsim. While the
+example here uses Ubuntu 16.04.1 server to have a list of exact steps,
+there are no requirements for using that specific distribution in the
+testing setup.
+
+The steps here describe how to run a guest VM for testing on a Linux
+host system.
+
+
+Install Ubuntu Server 16.04.1 as the host system for VMs
+
+- download installation image, e.g.,
+ http://releases.ubuntu.com/16.04.1/ubuntu-16.04.1-server-amd64.iso
+- install the host system with default settings
+- boot to the installed system
+- update the installed packages:
+ sudo apt update
+ sudo apt upgrade
+
+
+Install the prerequisite packages that may not have been installed by default
+
+# kvm for running the VM guests
+sudo apt install qemu-kvm
+
+# build tools
+sudo apt install build-essential git libpcap-dev libsqlite3-dev binutils-dev \
+ bc pkg-config libssl-dev libiberty-dev libdbus-1-dev \
+ libnl-3-dev libnl-genl-3-dev libnl-route-3-dev
+
+# tools used be the test scripts
+sudo apt install python-minimal python-crypto python-pyrad python-netifaces \
+ python-dbus python-gobject python-openssl bridge-utils ebtables tshark
+
+
+Enable kvm use for the user
+
+sudo adduser $USER kvm
+
+
+Download a snapshot of the hostap.git repository and build the programs
+
+cd
+git clone git://w1.fi/hostap.git
+cd hostap/tests/hwsim
+./build.sh
+cd vm
+cat > vm-config <<EOF
+KERNELDIR=~/wireless-testing
+MEMORY=512
+KVMARGS="-cpu host"
+EOF
+
+
+Build a Linux kernel for testing
+
+cd
+git clone git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-testing.git
+cd wireless-testing
+cp ~/hostap/tests/hwsim/vm/kernel-config .config
+make oldconfig
+make -j8
+
+
+Setup is now ready for testing. You can run a quick test to confirm that
+things work as expected:
+
+cd ~/hostap/tests/hwsim/vm
+./vm-run ap_open
+
+This should print out following style results:
+
+Starting test run in a virtual machine
+./run-all.sh: passing the following args to run-tests.py: ap_open
+START ap_open 1/1
+PASS ap_open 0.924019 2017-01-28 20:20:12.137717
+passed all 1 test case(s)
+ALL-PASSED
+
+Test run completed
+Logfiles are at /tmp/hwsim-test-logs/1485634801
+
+(If that "PASS ap_open" line does not show up, something unexpected has
+happened and the setup is not in working condition.)
+
+
+To run all available test cases in 7 parallel VMs, you can run
+following:
+
+cd ~/hostap/tests/hwsim/vm
+./parallel-vm.py 7
