Utility method to convert a VMware managed object into an attribute hash. This should only really be necessary for the real class. This method is expected to be called by the request methods in order to massage VMware Managed Object References into Attribute Hashes.
# File lib/fog/vsphere/compute.rb, line 61 def convert_vm_mob_ref_to_attr_hash(vm_mob_ref) return nil unless vm_mob_ref props = vm_mob_ref.collect! *ATTR_TO_PROP.values.uniq # NOTE: Object.tap is in 1.8.7 and later. # Here we create the hash object that this method returns, but first we need # to add a few more attributes that require additional calls to the vSphere # API. The hypervisor name and mac_addresses attributes may not be available # so we need catch any exceptions thrown during lookup and set them to nil. # # The use of the "tap" method here is a convenience, it allows us to update the # hash object without explicitly returning the hash at the end of the method. Hash[ATTR_TO_PROP.map { |k,v| [k.to_s, props[v]] }].tap do |attrs| attrs['id'] ||= vm_mob_ref._ref attrs['mo_ref'] = vm_mob_ref._ref # The name method "magically" appears after a VM is ready and # finished cloning. if attrs['hypervisor'].kind_of?(RbVmomi::VIM::HostSystem) then # If it's not ready, set the hypervisor to nil attrs['hypervisor'] = attrs['hypervisor'].name rescue nil end # This inline rescue catches any standard error. While a VM is # cloning, a call to the macs method will throw and NoMethodError attrs['mac_addresses'] = vm_mob_ref.macs rescue nil attrs['path'] = get_folder_path(vm_mob_ref.parent) end end
REVISIT: This is a naive implementation and not very efficient since we find ALL VM's and then iterate over them looking for the managed object reference id... There should be an easier way to obtain a reference to a VM using only the name or the _ref. This request is primarily intended to reload the attributes of a cloning VM which does not yet have an instance_uuid
