(follow-up)

I purged my configuration files for qemu (and libvirtd) and reinstalled
the whole thing.

When I try to run qemu without any option whatsoever:

phy0:~$ qemu-system-x86_64
qemu-system-x86_64: qemu_mprotect__osdep: mprotect failed: Permission denied
qemu-system-x86_64: mprotect of jit buffer: Permission denied

I don't know what should I do about that. I've no idea where the
error comes from.

phy0:~# qemu-system-x86_64 -version
QEMU emulator version 9.0.2

Thanks for your help
