Works for me:

We only send arm-core.xml for 32 bit CPUs: are you sure
you didn't select a 32 bit CPU either explicitly or by default
on the QEMU command line? Note that '-machine type=virt'
defaults to a Cortex-A15 even in qemu-softmmu-aarch64
(this is unfortunate but fallout from the fact that we started
the virt model with the A15. Maybe we should make it not
have a default and require a CPU specification...)
