def add_delta_disk_layer_on_all_disks
  spec = update_spec_add_delta_disk_layer_on_all_disks
  self.ReconfigVM_Task(:spec => spec).wait_for_completion
end

Add a layer of delta disks (redo logs) in front of every disk on the VM. This is similar to taking a snapshot and makes the VM a valid target for creating a linked clone.

Background: The API for linked clones is quite strange. We can’t create a linked straight from any VM. The disks of the VM for which we can create a linked clone need to be read-only and thus VC demands that the VM we are cloning from uses delta-disks. Only then it will allow us to share the base disk.

disks ()

Source

# File lib/rbvmomi/vim/VirtualMachine.rb, line 13
def disks
  self.config.hardware.device.grep(RbVmomi::VIM::VirtualDisk)
end

Retrieve all virtual disk devices. @return [Array] Array of virtual disk devices.

guest_ip ()

Source

# File lib/rbvmomi/vim/VirtualMachine.rb, line 19
def guest_ip
  g = self.guest
  if g.ipAddress && (g.toolsStatus == "toolsOk" || g.toolsStatus == "toolsOld")
    g.ipAddress
  else
    nil
  end
end

Get the IP of the guest, but only if it is not stale @return [String] Current IP reported (as per VMware Tools) or nil

macs ()

Source

# File lib/rbvmomi/vim/VirtualMachine.rb, line 7
def macs
  Hash[self.config.hardware.device.grep(RbVmomi::VIM::VirtualEthernetCard).map { |x| [x.deviceInfo.label, x.macAddress] }]
end

Retrieve the MAC addresses for all virtual NICs. @return [Hash] Keyed by device label.

  end
  spec
end

Updates a passed in spec to perform the task of adding a delta disk layer on top of all disks. Does the same as add_delta_disk_layer_on_all_disks but instead of issuing the ReconfigVM_Task, it just constructs the spec, so that the caller can batch a couple of updates into one ReconfigVM_Task.
