[Qemu-devel] [PATCH 5/6] blockdev-test: add test case for drive_add duplicate IDs |
Date: |
Tue, 10 Sep 2013 18:21:11 +0200 |
The following should work:
(qemu) drive_add if=none,id=drive0
(qemu) drive_del drive0
(qemu) drive_add if=none,id=drive0
Previous versions of QEMU produced a duplicate ID error because
drive_add leaked the options.
