      The installation of {product-title} failed when a performance profile was located in the extra manifests folder and targeted *master* or *worker* node roles. This was caused by the internal installation that processes the performance profile before the default *master* or *worker* node roles were created. With this release, the internal installation processes the performance profile after the node roles are created so that this issue no longer exists.

      Description of problem:

      The installer supports pre-rendering of the PerformanceProfile related manifests. However the MCO render is executed after the PerfProfile render and so the master and worker MachineConfigPools are created too late.

This causes the installation process to fail with:

      4.14.0-rc.6

      How reproducible:

      Always

      Steps to Reproduce:

      1. Add an SNO PerformanceProfile to extra manifest in the installer. Node selector should be: "node-role.kubernetes.io/master="
2.
3.

      Actual results:

      no MCP found that matches performance profile node selector "node-role.kubernetes.io/master="

      Expected results:

      Installation completes
