VMware vSphere Hot Add and Hot Plug
KB ID 0000527 Problem I was trying to hot add some memory to a VM the other day, and found the option grayed out. Normally I’d just down the VM, add the memory, then bring it back up. But it was a production server and I was pretty sure the OS supported it. A quick Google search told me why it was grayed out, but it also transpired there was little to no information on what version of Windows hot add and hot plug would work...
