 QEMU is used for KVM VM vhost-user testing enviroment. By default,
 standard QEMU version is used, preinstalled from OS repositories
-(qemu-2.11.1 for Ubuntu 18.04, qemu-2.5.0 for Ubuntu 16.04). The path
+(qemu-2.11.1 for Ubuntu 18.04). The path
 to the QEMU binary can be adjusted in `Constants.py`.
 
 FD.io CSIT performance lab is testing VPP vhost-user with KVM VMs using
 following environment settings:
 
-- Tests with varying QEMU virtio queue (a.k.a. vring) sizes: [vr1024]
-  1024 descriptors to optimize for packet throughput.
-- Tests with varying Linux :abbr:`CFS (Completely Fair Scheduler)`
-  settings: i) [cfs] default settings, ii) [cfsrr1] CFS RoundRobin(1)
-  policy applied to all data plane threads handling test packet path
-  including all VPP worker threads and all QEMU testpmd poll-mode
-  threads.
-- Resulting test cases are all combinations with [vr1024] and
-  [cfs,cfsrr1] settings.
-- Adjusted Linux kernel :abbr:`CFS (Completely Fair Scheduler)`
-  scheduler policy for data plane threads used in CSIT is documented in
-  `CSIT Performance Environment Tuning wiki
-  <https://wiki.fd.io/view/CSIT/csit-perf-env-tuning-ubuntu1604>`_.

-Testing with different CFS settings enables verifying the impact of
-making VPP and VM data plane threads less susceptible to other Linux OS
-system tasks hijacking CPU cores running those data plane threads.
