Anybody with a Cortex-A15 KVM VM is just going to have to stay
with their pre-existing ancient hardware, their pre-existing
host kernel and their pre-existing QEMU binary. That's what
"we deprecated and then dropped support for this" means:
we no longer support running that kind of VM, so users who
were doing it need to either do something else instead, or
else just keep on going with the old versions they have.
