Regarding the path:

  VM->Edit Settings->Resources

Open in new window


If I set the VM memory to 32 GB,

can the memory reservation ever be set to zero  (I have some confusion on this)

Thanks

The memory reservation (if you are using this function) has to be set to a value.

This value GUARANTEES,this VM will always be given this value, e.g. if you set 32GB, 32GB will always be reserved and guaranteed for this VM.

The Hypervisor cannot take it away, for use with other virtual machines.

Why would you want to try and set memory to ZERO ?

if you guaranteed zero memory, the VM would not run.

No you cannot set it to zero.

Try it! and see what happens!
