# python
import libvirt conn = libvirt.open('qemu:///system') dom = conn.lookupByName('f14') dir(dom) ['ID', 'OSType', 'UUID', 'UUIDString', 'XMLDesc', '__del__', '__doc__', '__init__', '__module__', '_conn', '_o', 'abortJob', 'attachDevice', 'attachDeviceFlags', 'autostart', 'blockInfo', 'blockPeek', 'blockStats', 'connect', 'coreDump', 'create', 'createWithFlags', 'destroy', 'detachDevice', 'detachDeviceFlags', 'hasCurrentSnapshot', 'hasManagedSaveImage', 'info', 'interfaceStats', 'isActive', 'isPersistent', 'isUpdated', 'jobInfo', 'managedSave', 'managedSaveRemove', 'maxMemory', 'maxVcpus', 'memoryParameters', 'memoryPeek', 'memoryStats', 'migrate', 'migrateSetMaxDowntime', 'migrateToURI', 'name', 'openConsole', 'pinVcpu', 'reboot', 'resume', 'revertToSnapshot', 'save', 'schedulerParameters', 'schedulerType', 'setAutostart', 'setMaxMemory', 'setMemory', 'setMemoryParameters', 'setSchedulerParameters', 'setVcpus', 'setVcpusFlags', 'shutdown', 'snapshotCreateXML', 'snapshotCurrent', 'snapshotListNames', 'snapshotLookupByName', 'snapshotNum', 'suspend', 'undefine', 'updateDeviceFlags', 'vcpus', 'vcpusFlags']
see "attachDevice", "attachDeviceFlags", and "updateDeviceFlags", (in case of your guest already has CDROM device). to get how to use them:
help(dom.attachDevice)

--------------------------__ I'm sorry that I as you do,but I don't find the "attachDeviceFlags" and "updateDeviceFlags"
dir(dom) ['ID', 'OSType', 'UUID', 'UUIDString', 'XMLDesc', '__del__', '__doc__', '__init__', '__module__', '_conn', '_o', 'attachDevice', 'autostart', 'blockPeek', 'blockStats', 'connect', 'coreDump', 'create', 'destroy', 'detachDevice', 'info', 'interfaceStats', 'maxMemory', 'maxVcpus', 'memoryPeek', 'migrate', 'name', 'pinVcpu', 'reboot', 'ref', 'resume', 'save', 'schedulerParameters', 'schedulerType', 'setAutostart', 'setMaxMemory', 'setMemory', 'setSchedulerParameters', 'setVcpus', 'shutdown', 'suspend', 'undefine', 'vcpus']
I think this is the version of the problem . My libvir.py's version is 0.6.3 And when I use "attachDevice" to attach cdrom , I get "no wrong"(return value is "0"),but the vm not find the cdrom. Regards Seven

Yes, virDomainAttachDeviceFlags was introduced in 0.7.7, though not sure if Python binding include it timely, 0.6.3 definitely doesn't support it. :-)
And when I use "attachDevice" to attach cdrom , I get "no wrong"(return value is "0"),but the vm not find the cdrom.
Not sure if it's bug, but could you confirm it's attached, but just not mounted? Regards Osier
