# HG changeset patch # User Wayne Xia <xiawenc@linux.vnet.ibm.com> # Date 1316154275 -28800 # Node ID 04b73e1cdc3087a390b9790c13b42ebacbc5d5ba # Parent fb09136deb494008eb3aacee420ad74da7d7c294 Fix the problem that libvirt-cim can't find cdrom device that do not have disk This patch would allow define a system with a empty CDROM device, and allow method modify resource settings to insert ISO files into an empty CDROM device. Examples: InvokeMethod(ModifyResourceSettings): ResourceSettings: ['instance of KVM_DiskResourceAllocationSettingData {\nResourceType = 17;\nInstanceID = "test/hdc";\nEmulatedType = 1;\nVirtualDevice = "hdc";\nAddress = "";\n};'] InvokeMethod(ModifyResourceSettings): ResourceSettings: ['instance of KVM_DiskResourceAllocationSettingData {\nResourceType = 17;\nInstanceID = "test/hdc";\nEmulatedType = 1;\nVirtualDevice = "hdc";\nAddress = "/var/lib/libvirt/images/test-disk.iso";\n};'] Note that the Address property should be set to "", not None(not set), to tell that user want an ejection.
