#traverse_folders_for_pool_clustercompute(folder, objectname) ⇒ RbVmomi::VIM::ClusterComputeResource, ...

Find the given pool or compute resource

Parameters:

• folder (RbVmomi::VIM::Folder) —

  the folder from which to start the search, most likely dc.hostFolder

• objectname (String) —

  name of the object (pool or cluster/compute) to find

Returns:

• (RbVmomi::VIM::ClusterComputeResource, RbVmomi::VIM::ComputeResource, RbVmomi::VIM::ResourcePool)
