No, that's not supported. The only board we have that works in
KVM is the 'virt' board. I guess in theory it could be bodged
into working, but AArch64 KVM isn't really intended as "run
an arbitrary guest kernel that uses an arbitrary machine and
set of devices", it's more "run a guest kernel that knows it's
running as a VM" (for instance there is no way to give the
guest something that says it's a Cortex-A53 -- you always get
the CPU type the host has).
