Re: [Libvir] libvirt 0.1.8 Help

["Omer Khalid" <Omer Khalid cern ch>]

I tried with the traceback. Here is the output:

[('<stdin>', 3, '?', None), ('/usr/lib/python2.3/site-packages/libvirt.py', 268, 'lookupByID', "if ret is None:raise libvirtError('virDomainLookupByID() failed')")]
[('<stdin>', 3, '?', None), ('/usr/lib/python2.3/site-packages/libvirt.py', 268, 'lookupByID', "if ret is None:raise libvirtError('virDomainLookupByID() failed')")]

Thanks
Omer

Try adding an exception handler that prints out useful information
rather than raw python object references for a start... Its impossible
to debug this unless you get the text associated with the exception.
