+SUT Configuration - Host OS Linux
+---------------------------------
+
+System provisioning is done by combination of PXE boot unattented
+install and
+`Ansible <https://www.ansible.com>`_ described in `CSIT Testbed Setup`_.
+
+Below a subset of the running configuration:
+
+#. Haswell - Ubuntu 16.04.1 LTS
+
+::
+
+    $ lsb_release -a
+    No LSB modules are available.
+    Distributor ID:	Ubuntu
+    Description:	Ubuntu 16.04.1 LTS
+    Release:	16.04
+    Codename:	xenial
+
+#. Skylake - Ubuntu 18.04 LTS
+
+::
+
+    $ lsb_release -a
+    No LSB modules are available.
+    Distributor ID: Ubuntu
+    Description:    Ubuntu 18.04 LTS
+    Release:        18.04
+    Codename:       bionic
+
+**Kernel boot parameters used in CSIT performance testbeds**
+
+- **isolcpus=<cpu number>-<cpu number>** used for all cpu cores apart from
+  first core of each socket used for running VPP worker threads and Qemu/LXC
+  processes
+  https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt
+- **intel_pstate=disable** - [X86] Do not enable intel_pstate as the default
+  scaling driver for the supported processors. Intel P-State driver decide what
+  P-state (CPU core power state) to use based on requesting policy from the
+  cpufreq core. [X86 - Either 32-bit or 64-bit x86]
+  https://www.kernel.org/doc/Documentation/cpu-freq/intel-pstate.txt
+- **nohz_full=<cpu number>-<cpu number>** - [KNL,BOOT] In kernels built with
+  CONFIG_NO_HZ_FULL=y, set the specified list of CPUs whose tick will be stopped
+  whenever possible. The boot CPU will be forced outside the range to maintain
+  the timekeeping. The CPUs in this range must also be included in the
+  rcu_nocbs= set. Specifies the adaptive-ticks CPU cores, causing kernel to
+  avoid sending scheduling-clock interrupts to listed cores as long as they have
+  a single runnable task. [KNL - Is a kernel start-up parameter, SMP - The
+  kernel is an SMP kernel].
+  https://www.kernel.org/doc/Documentation/timers/NO_HZ.txt
+- **rcu_nocbs** - [KNL] In kernels built with CONFIG_RCU_NOCB_CPU=y, set the
+  specified list of CPUs to be no-callback CPUs, that never queue RCU callbacks
+  (read-copy update).
+  https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt
+- **numa_balancing=disable** - [KNL,X86] Disable automatic NUMA balancing.
+- **intel_iommu=enable** - [DMAR] Enable Intel IOMMU driver (DMAR) option.
+- **iommu=on, iommu=pt** - [x86, IA-64] Disable IOMMU bypass, using IOMMU for
+  PCI devices.
+- **nmi_watchdog=0** - [KNL,BUGS=X86] Debugging features for SMP kernels. Turn
+  hardlockup detector in nmi_watchdog off.
+- **nosoftlockup** - [KNL] Disable the soft-lockup detector.
+- **tsc=reliable** - Disable clocksource stability checks for TSC.
+  [x86] reliable: mark tsc clocksource as reliable, this disables clocksource
+  verification at runtime, as well as the stability checks done at bootup.
+  Used to enable high-resolution timer mode on older hardware, and in
+  virtualized environment.
+- **hpet=disable** - [X86-32,HPET] Disable HPET and use PIT instead.
+
+**Applied command line boot parameters:**
