Reservation reserve resource for specific VMs.

Reservation - Guaranteed memory allocation for this virtual machine.

Limit - Upper limit for this virtual machine’s memory allocation.

Unlimited - No upper limit is specified

if you set unlimited for VM RAM, it will utilizes all assigned memory. e.g if you have assigned 4 GB, it will use all that.

or if you limit your VM to use only 3 GB then thought it will have 4 GB assigned in it will not cross 3 GB Limits.

There is no harm in setting unlimited for VMs unless your VMs are really need lot of CPU and RAM and there is resource crunch.
