I think the current aarch64 support in qemu is for running on an aarch64 machine.
But there's patches posted for everything else: build qemu-system-aarch64,
aarch64 emulation, and aarch64 kvm. The qemu-system-aarch64 bit may land
before everything else actually, but it won't be much different from
qemu-system-arm.
Yes, aarch64 kvm has been tested with qemu-system-aarch64. Initial patches
for QEMU aarch64 were aimed at supporting only KVM but recently quite
a few patches have been posted for TCG aarch64 emulation.
Largely, the approach in QEMU is to have qemu-system-aarch64 share most
of the code with qemu-system-arm. In fact, for qemu-system-aarch64 TCG
emulation and aarch64 kvm code is located in target-arm directory which is
originally meant for qemu-system-arm.
