The title of your thread isn't possible as when you launch a VM it locks the VMDK file.
You can create a template VM which you can create other VMs off using the template as a basis.
(sorry, nicked the enter key by mistake which posted before I intended).
This scenario appears to be supported in vmware view I was just wondering if it's supported under general esx implementations?
It seems I'll also be able to get this type of consolidation via dedupe on my san if I structure my datastores with similar images.
I can't see how this would work in normal ESX as you would end up with alot of locking problems in the VMDK. I assume VMware View would use a basis VMDK and then the machines would run on snapshots so basically it wouldn't be sharing the base VMDK it would be using its own snapshots, but I don't really know much about VMware View and how it works, that is just my assumption.
What you are refering to is the concept of Linked Clones, this is something completely different from sharing a single VMDK. with linked clones you are actually running mulitple snapshots of a single Machine. this fuinctionality is not available in Raw ESX but is a feature of Lab Manager and VMware View Premium.
