Ah no, wait... On x86, there are two KVM address spaces, so you have to
pass "as" to has_memory.  To detect KVM address spaces, you can allocate
an array with kvm_check_extension(kvm, KVM_CAP_MULTI_ADDRESS_SPACE)
elements (default 1 if the capability is not available), and fill it in
kvm_memory_listener_register.  Then you an search for the address space
in that array, it's very small and cheap.

Promise to merge quickly with that change.

Thanks,

Paolo
