Peter, is your enter key broken? You seem to be typing all your text in
a single unreadable paragraph.

You're saying that firmware basically has two choices:
1. Accept all the memory up front and boot slowly, but reliably
2. Use thus "unaccepted memory" mechanism, boot fast, but risk that the
VM loses a bunch of memory.

If the guest can't even boot because of a lack of memory, then the
pre-accepted chunk is probably too small in the first place.

If the customer screws up, they lose a bunch of the RAM they paid for.
That seems like a rather self-correcting problem to me.
