I gave up doing things this way as Qemu kept changing under me, voiding my scripts. I now use 'virt-manager' relatively painlessly.

That IP may have been issued by a Qemu dhcp server.

The first step is to confirm Qemu is not messing with stuff it shouldn't... Spin up the VM and confirm that your host network settings have not been altered/added to. You must do this when the VM is running.
