class RbVmomi::VIM::VirtualMachine
Public Instance Methods
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.

Retrieve all virtual disk devices. @return [Array] Array of virtual disk devices.
# File lib/rbvmomi/vim/VirtualMachine.rb, line 10 def disks self.config.hardware.device.grep(RbVmomi::VIM::VirtualDisk) 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
# File lib/rbvmomi/vim/VirtualMachine.rb, line 16 def guest_ip g = self.guest if g.ipAddress && (g.toolsStatus == "toolsOk" || g.toolsStatus == "toolsOld") g.ipAddress else nil end end
Retrieve the MAC addresses for all virtual NICs. @return [Hash] Keyed by device label.
# File lib/rbvmomi/vim/VirtualMachine.rb, line 4 def macs Hash[self.config.hardware.device.grep(RbVmomi::VIM::VirtualEthernetCard).map { |x| [x.deviceInfo.label, x.macAddress] }] 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.
