+Common virtual machine life cycle events test specification
+===========================================================
+
+.. toctree::
+ :maxdepth: 2
+
+Scope
+=====
+
+The common virtual machine life cycle events test area evaluates the ability of
+the system under test to behave correctly after common virtual machine life
+cycle events. The tests in this test area will evaluate:
+
+- Stop/Start a server
+- Reboot a server
+- Rebuild a server
+- Pause/Unpause a server
+- Suspend/Resume a server
+- Resize a server
+- Resizing a volume-backed server
+- Sequence suspend resume
+- Shelve/Unshelve a server
+- Cold migrate a server
+- Live migrate a server
+
+References
+==========
+
+- iSCSI
+
+ - https://docs.openstack.org/liberty/config-reference/content/config-iscsi-storage.html
+
+Definitions and abbreviations
+=============================
+
+The following terms and abbreviations are used in conjunction with this test area
+
+- API - Application Programming Interface
+- NFVi - Network Functions Virtualization infrastructure
+- VIM - Virtual Infrastructure Manager
+- VM - Virtual Machine
+
+System Under Test (SUT)
+=======================
+
+The system under test is assumed to be the NFVi and VIM in operation on a
+Pharos compliant infrastructure.
+
+Test Area Structure
+===================
+
+The test area is structured based on common virtual machine life cycle events.
+Each test case is able to run independently, i.e. irrelevant of the state
+created by a previous test. Specifically, every test performs clean-up
+operations which return the system to the same state as before the test.
