+Userguide Introduction
+======================
+
+Overview
+--------
+
+The project "NFV Hypervisors-KVM" makes collaborative efforts to enable NFV
+features for existing hypervisors, which are not necessarily designed or
+targeted to meet the requirements for the NFVI.The KVM4NFV scenario
+consists of Continuous Integration builds, deployments and testing
+combinations of virtual infrastructure components.
+
+KVM4NFV Features
+----------------
+
+Using this project, the following areas are targeted-
+
+* Minimal Interrupt latency variation for data plane VNFs:
+   * Minimal Timing Variation for Timing correctness of real-time VNFs
+   * Minimal packet latency variation for data-plane VNFs
+* Inter-VM communication
+* Fast live migration
+
+Some of the above items would require software development and/or specific
+hardware features, and some need just configurations information for the
+system (hardware, BIOS, OS, etc.).
+
+We include a requirements gathering stage as a formal part of the project.
+For each subproject, we will start with an organized requirement stage so
+that we can determine specific use cases (e.g. what kind of VMs should be
+live migrated) and requirements (e.g. interrupt latency, jitters, Mpps,
+migration-time, down-time, etc.) to set out the performance goals.
+
+Potential future projects would include:
+
+* Dynamic scaling (via scale-out) using VM instantiation
+* Fast live migration for SR-IOV
+
+The user guide outlines how to work with key components and features in
+the platform, each feature description section will indicate the scenarios
+that provide the components and configurations required to use it.
+
+The configuration guide details which scenarios are best for you and how to
+install and configure them.
+
+General usage guidelines
+------------------------
+
+The user guide for KVM4NFV features and capabilities provide step by step
+instructions for using features that have been configured according to the
+installation and configuration instructions.
+
+Scenarios User Guide
+--------------------
+
+The procedure to deploy/test `KVM4NFV scenarios`_ in a nested virtualization
+or on bare-metal environment is mentioned in the below link. The kvm4nfv user guide can
+be found at docs/scenarios
+
+.. code:: bash
+
+    http://artifacts.opnfv.org/kvmfornfv/docs/index.html#kvmfornfv-scenarios-overview-and-description
+
+.. _KVM4NFV scenarios: http://artifacts.opnfv.org/kvmfornfv/docs/index.html#kvmfornfv-scenarios-overview-and-description
+
+The deployment has been verified for `os-nosdn-kvm-ha`_, os-nosdn-kvm-noha, `os-nosdn-kvm_ovs_dpdk-ha`_,
+`os-nosdn-kvm_ovs_dpdk-noha`_ and `os-nosdn-kvm_ovs_dpdk_bar-ha`_, `os-nosdn-kvm_ovs_dpdk_bar-noha`_ test scenarios.
+
+For brief view of the above scenarios use:
