From: Yoshiaki Tamura <tamura.yoshi...@lab.ntt.co.jp> This fixes the following scenario using QMP.
First, put a bogus argument "foo" to "type", which results in an error. {"execute": "netdev_add", "arguments": { "type": "foo", "id": "netdev1" } } Then, call it again with correct argument "user". {"execute": "netdev_add", "arguments": { "type": "user", "id": "netdev1" } } This results in "DuplicatedId" error. Because the first command was invalid, it should be able to reuse the same "id", and the second command should work.
