But we have qemu [0] that emulates quite a lot of Instruction Sets. How comes that it is allowed to exist, qemu is emulating quite a lot of instruction sets [1] ?

The support is there, yes, but it's always been a grey / largely unenforced black area. As soon as the emulator cuts into chip sales in any significant way the tolerance for its use would stop.

IANAL, this is simply what legal folks are saying on this topic.

Can you run qemu fast enough to be competitive with Intel? And I mean full emulation, not something that requires running on x86.
