Enable Hot-Add of Memory with Hyper-V

Q: I want to be able to hot-add memory to a Hyper-V virtual machine (VM) but don't want to use Dynamic Memory--is this possible?

A: Typically, the way Dynamic Memory works is you set three values related to memory:

For example, you might set the Startup RAM to 1024MB, the Minimum RAM to 512MB and the Maximum RAM to 4096MB. This allows the VM to have additional memory added based on the memory requirements of processes running inside the guest OS and the amount of RAM physically available on the host.

Some organizations don't want to use Dynamic Memory but want the ability to hot-add memory if required. The trick is to do the following:

Although technically you are using Dynamic Memory, you have complete control of when and how the memory is allocated using this method; you're essentially hot-adding memory manually as needed.
