Problem:

In section 5.3.3 
"The given argument is appended to the tuned cpu-partitioning profile"
HostIsolatedCpusList: "'2,4,6,8,10,12,14,18,20,22,24,26,28,30'"

However, section C.3.3 which is a sample network-environment.yaml the param is shown as follows.


  # The given args will be appended to the tuned cpu-partitioning profile.
  HostIsolatedCoreList: "2,4,6,8,10,12,14,18,20,22,24,26,28,30"

HostIsolatedCoreList also exists in the first-boot.yaml example

        params:
          $COMPUTE_HOSTNAME_FORMAT: {get_param: ComputeHostnameFormat}
          $TUNED_CORES: {get_param: HostIsolatedCoreList}

Fix:
Change HostIsolatec CPUsList to Host IsolatedCoreList.
