It is not our focus at the moment; we are targeting operating systems that support a modern ARMv7 machine with GIC support. That said, it might be possible to run legacy guests in the future, introducing more emulation to the hypervisor.

We expect most hardware vendors to provide a GIC with virtualization support. However if they do not, in order to support their boards we'll have to do more emulation in the hypervisor.
