Hi Peter, Vadim,
Great to know the QEMU team has thought about this before. I concede that
my idea might not fit nicely into QEMU's design architecture, it likely
would be an entirely different accelerator or standalone emulator, and
even then, it would be a hit-or-miss for users as far as wheth

Hi Peter,
Yes, I know. Thank you very much for your response (including the follow-up),

Yes, I know. Thank you very much for your response (including the
