# HG changeset patch # User Eduardo Lima (Etrunko)<eblima@br.ibm.com> # Date 1317409066 10800 # Node ID 85c624ef88f4e1487f95a5e50674a626a4ebf8f4 # Parent f4bcd9833525c6914f61e29e9d2d8adbac240682 [TEST] 32_modify_cdrom_media.py: new test for VirtualSystemManagementService
This test case covers a requirement to change the media in the CDROM using libvirt-cim, which is done via a ModifyResourceSettings call.
