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 On 6/27/07, Daniel P.

Hi,
I have the following code working on libvirt 0.1.9:
######################################## conn = libvirt.openReadOnly(None) if conn == None: print 'Failed to open connection to the hypervisor' #sys.exit(1)
try: domains = conn.listDomainsID() num = conn.numOfDomains() except: print 'Failed to find the list of domains'
for i in range(num): try: dom0 = conn.lookupByID(domains[i]) domInfo = dom0.info() except: print "Unexpected error:", sys.exc_info()
##############################################
For legacy reason, I have to get it working on libvirt 0.1.8 but I am constantly getting the following error:
Unexpected error: (<class libvirt.libvirtError at 0xb7f49f2c>, < libvirt.libvirtError instance at 0xb7f4f2cc>, <traceback object at 0xb7f44c5c>)
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.
