106 <https://docs.fd.io/vpp/17.01/release_notes_1701.html>`_.
\r
108 Additionally, vhost-VM performance improvements are due to both VPP code
\r
109 optimizations as well as due to the FD.io CSIT Linux KVM test environment
\r
110 optimizations for vhost-VM tests - see section "2.1.7. Methodology: KVM VM
