This slows down operations at the moment." I guess that's not a horrible place to start. It's also not *horribly* different from how guests work today. If hosts lazily allocate RAM, they'll see largely the same kind of behavior. What ends up determining how much memory is pre-accepted versus being done from the guest? Is that just a normal part of setting up a TDX guest, like from the qemu cmdline? Or, is there some convention with the virtual firmware?
