QEMU has default devices for machine types and is apparently trying to install an e1000 NIC at guest address 02.0, you either need to disable these defaults with a '-nodefaults' option, disable the NIC with a '-net none' option, or place the NIC at a different address by explicitly defining it and setting the address.
