KVM requires the target CPU to be at least ARMv8, because we only support the "host" cpu type, and all KVM host CPUs are v8, which means you can't pass a v7 CPU as the target CPU. (This used to not be true when we still supported running KVM on a v7 CPU like the Cortex-A15, in which case you could pass it to the guest.) thanks -- PMM
