How can I set the memory reservation on all VMs to “0”?
I’m trying to write a script that will set the memory reservation on all of the guest VMs in a cluster to “0”. We were reserving too much memory, and this setting should allow the VMWare facilities to manage the memory reservations for me. I have hundreds of VMs to update, so I can’t do it by hand. I’m hoping it can be done with the CLI.
