One big question that comes up is how do you patch Linked Clones, currently if you have a master image of WinXP-SP2 and you have 20 LC's linking off that base image, if you want to go to WinXP-SP3, you'll need to update your master and redeploy the 20 LC's again as the changes to the base are different from when you created the LC's originally. When creating Linked Clones, the base image must be off this is the same exact requirement in VMware View 3, you will not be able to Link from a running VM as the disk is locked and you'll need to take a snapshot. Non-persistent LC's are great in a lab environment and this is something that I've worked on with my colleague Tuan at UCSB ResNet:

You may want to go through some of the VMware View 3 documents that describe Linked Clones in greater detail to get a better understanding and here is a quick snippet when View 3 was released that gives you some high level information: ДЇrom my previous post you have 2 options, If you're looking to preserve user's data you'll need to create a second data disk that is attached to each VM OR you use full clones and not Linked Clones, remember LC's aren't for everyone, depending on your use case. The commonality between all the LC's is the common base OS, if you try to merge you'll probably lock the rest of the LC's out from functioning.

I don't think you completely understand how Linked Clones work, you will not be able to merge the individual LC's into the base image as each LC uses the base image as an OS references and all differentials of each VM is written to it's individual delta file. You'll need to write some logic for the second case but that's generally how it works and how VMware View 3 provides Linked Clones support.Дў) There are no VI API support for Linked Clones on a standalone ESX/ESXi host, you'll need to vCenter instance and the only available method that supports this is the one I've described in an earlier post. Persistent on the other hand is achieved by adding a user disk which uses application redirection to store all changes from the user to their respective data disk and the OS disk continues to reference the gold/master image. With non-persistent you will not be keeping the user's state of the OS, this is great for a lab environment where each night or morning user's will always get a fresh OS and changes on the system will not persist and in VMware View this operation is called 'Recompose' and it's similar to that of our script where we take an additional snapshot on the Linked Clone and the VM is reverted back to the original Linked Clone via the pristine snapshot that was taken after the LC was created. With VMware View the two use cases are (non-persistent and persistent LC's). If you find this information useful, please award points for 'correct' or 'helpful'.ДЎ) Generally with Linked Clones you'll have a single gold/master image and then you'll create few dozen or so Linked Clones, you will not be able to merge the deltas back to the base as you can see there will be a problem since each LC will map back to the master.

You can find more information once vSphere GA's and the new VI API reference documents are released, though if you're looking to implement Linked Clones today, you can take a look at VMware View 3 product which provides support for Linked Clones or you can take a look at two scripts I wrote that creates Linked Clones similar to that of View: In the next release of vSphere, the vSphere SDK will provide a way of implementing Linked Clones and this will be a parameter that can be specify to CloneVM_Task() specifically in the VirtualMachineRelocateSpec where you'll specify diskMoveType to createNewChildDiskBacking if you want to implement a full clone and this will require you to have vCenter access. What you're referring to is called Linked Clones, in the current VI API, there are no methods that supports this functionality.
