What about kvm (or xen) as accelerator? Would that work?
IIUC this tests boots a nested Xen guest running at Aarch64 EL2,
and at this point we can only run EL2/EL3 on TCG. HVF and KVM
can not for now (we are working on it).
I don't know if Xen can accelerate EL2, it would need support for
such hardware (like the Apple Silicon M4). Cc'ing Xen folks to
figure it out.
