+The results of the testsuite reside in the VM root user's home directory:
+
+ vagrant ssh
+ sudo -s
+ cd /root/build
+ ls tests/system*
+
+### Native
+
+The datapath testsuite as invoked by Vagrant above may also be run
+manually on a Linux system with root privileges. These tests may take
+several minutes to complete, and cannot be run in parallel.
+
+#### Userspace datapath
+
+To invoke the datapath testsuite with the userspace datapath:
+
+ make check-system-userspace
+
+The results of the testsuite are in tests/system-userspace-traffic.dir/.
+
+#### Kernel datapath
+
+Make targets are also provided for testing the Linux kernel module.
+Note that these tests operate by inserting modules into the running
+Linux kernel, so if the tests are able to trigger a bug in the OVS
+kernel module or in the upstream kernel then the kernel may panic.
+
+To run the testsuite against the kernel module which is currently
+installed on your system:
+
+ make check-kernel
+
+To install the kernel module from the current build directory and
+run the testsuite against that kernel module:
+
+ make check-kmod
+
+The results of the testsuite are in tests/system-kmod-traffic.dir/.
