Hi all,
I want to attach cdrom by libvirt.py .But can't find a func in libvirt.py can finish this work.
Who can help me ?
Regard
# 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
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
