This domain definition makes no sense:

1) you have <boot dev='hd'/> listed, but not <disk> devices.

2) you have 2 <interface type='internal'> devices, which I've said
before is supported only for vbox domains.

3) all of your interfaces have <model type='am79x97x'/>, but those
devices are not supported by qemu/kvm.

If you want to try a qemu/kvm domain, you really should install
virt-manager and let it create the domain for you, that way you'll be
assured to have all the necessary pieces.

You have no valid device that could be booted from.
