ATP Memory Ballooning & Hyptherthreading
#1 Enabling "Reserve all guest memory (All locked)" on a Per VM basis is enough and even preferred.
#2 You can try running with Hyper Threading, it might be OK, depending on how strong the server is, but if you encounter health alerts about overloads, it might be related to Hyper threading turned on.

EdLarge the guidance you received from EliOfek is solid, and accurate. Just to add some additional comments, keep in mind that when you reserve the memory, the memory can only be used by that VM, so the trickle down impact (especially if you apply reservations to many VMs in the same cluster) would be performance impact to other VMs. Because memory swap is disabled by default you of course don't get that advantage either.
Of course, if you don't have more VM vMem deployed than you have physical you are good, but if you have overcommitted memory keep and eye out on your other VMs.
If you start running into performance issues across the cluster, look at share value as an alternative or add memory.
Good luck
