      Description of problem:

      Getting the following error when calling the vshphere compute resource API.

      # curl -H "Accept: application/json" -u "username:password"  -v https://satellite.example.com/api/v2/compute_resources/1 | jq
 {
  "error": {
    "message": "uninitialized constant Fog::Vsphere::Compute::ResourcePool"
  }

       

       

      How reproducible:

      Easy

       

      Is this issue a regression from an earlier version:

      No. The issue is there for some years, but never found the root cause or fully fixed.

      For more information please refer to the links below:

      https://github.com/theforeman/foreman/pull/6803

      https://github.com/fog/fog-vsphere/pull/267

       

      Steps to Reproduce:

      1. Create a compute resource connect to a Vcenter and enable caching.

      2.  Create and save a compute profile for it and fill in everything, especially the cluster and resources field.

      3. Call the compute resource show API above to make sure we cached the data.

      4. Restart foreman service "systemctl restart foreman"

      5. Run the API call above again.

      Actual behavior:
      uninitialized constant Fog::Vsphere::Compute::ResourcePool

      Expected behavior:

      no error

      Business Impact / Additional info:

      Satellite loads the Fog classes on demand when API is called to the Vcenter. If Satellite is not yet call to the API since the last restart, then we will get the error loading the cached data.
