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.

amelius • Oct 14, 2023 • View on HN

Isn't this already implemented in QEMU?

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

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?
