We're a dev shop so we make heavy use of VMs and snapshots for testing. This works great most of the time, but occasionally I discover some setting in a VM that needs to be changed across all my snapshots.
For example, I recently created a Vista VM and only gave it 512MB of RAM. The VM already has about 18 snapshots, and I'd really, really like to avoid recreating all of them if possible.
Is there a quick way to propagate VMWare-level changes like this across all the VM's snapshots?
I'm using ESX 3.5 but advice from any other versions (especially Workstation) is welcome.
