+OVS out-of-tree compilation environment can be set up with:
+
+ ./boot.sh
+ vagrant provision --provision-with configure_ovs,build_ovs
+
+This will set up an out-of-tree build environment in /home/vagrant/build.
+The source code can be found in /vagrant. Out-of-tree build is preferred
+to work around limitations of the sync file systems.
+
+To recompile and reinstall OVS using RPM:
+
+ ./boot.sh
+ vagrant provision --provision-with configure_ovs,install_rpm
+
+Two provisioners are included to run system tests with the OVS kernel
+module or with a userspace datapath. This tests are different from
+the self-tests mentioned above. To run them:
+
+ ./boot.sh
+ vagrant provision --provision-with configure_ovs,test_ovs_kmod,test_ovs_system_userspace
