libvir-list is for the *development* of libvirt: for
questions related to *running* libvirt, please use the
libvirt-users mailing list instead.

If you're running libvirt >= 1.3.5 and QEMU >= 2.6.0, both
released about a year ago, you should get GICv3 out of the
box because of the capabilities of your hardware.

That said, aarch64 support has been steadily improving
throughout the stack, so I would strongly recommend you
don't stop there and install the very latest upstream
releases of all components instead.
