Honestly QEmu is a better choice for this kind of things.

Unicorn / QEMU have done it already, no?

Yes, it's all just implemented using qemu helpers. I expect performance will be terrible.

Isn't this already implemented in QEMU?

dastx Feb 25, 2021 View on HN

The underlying tech is QEMU, so probably equivalent or better.

bpye Jun 6, 2019 View on HN

Qemu has a backend too if I'm not mistaken?

jetzzz Nov 27, 2018 View on HN

QEMU can do much more than this.

Possibly they're using QEMU to run Intel code?

mongol Jul 18, 2021 View on HN

What does this do that regular KVM + Qemu does not?

amelius Nov 23, 2023 View on HN

Is QEMU a practical alternative?
