Description Shaolong Hu 2013-07-12 02:59:28 UTC 
Description of problem:
------------------------
Use "drive_add" with an invalid bus type "if=XXX" takes the drive id, following drive_add with same drive id fails.


Version-Release number of selected component (if applicable):
--------------------------------------------------------------
qemu-kvm-1.5.1-2.el7.x86_64


How reproducible:
------------------
100%

Steps to Reproduce:
-----------------------
(qemu) drive_add auto file=/root/nfs/RHEL-Server-7.0-64-virtio.qcow2,id=drive-scsi0-0-3,format=qcow2,werror=stop,if=dsfsd,cache=none,media=disk
unsupported bus type 'dsfsd'
(qemu) drive_add auto file=/root/nfs/RHEL-Server-7.0-64-virtio.qcow2,id=drive-scsi0-0-3,format=qcow2,werror=stop,if=none,cache=none,media=disk
Duplicate ID 'drive-scsi0-0-3' for drive


Expected results:
-------------------
Failed drive_add should not take the drive id.
