I am trying to set Metada of running virtual machine, but its giving me an error.

Here is my code

import libvirt

conn = libvirt.open('qemu+tcp://10.0.128.12/system')

dom = conn.lookupByName('virtspace')

type = 'VIR_DOMAIN_METADATA_DESCRIPTION'

key = ''

uri = ''

dom.setMetadata(conn, type, 'myDescription', key, uri)

and here is the error.

Traceback (most recent call last):

File "setMeta.py", line 11, in <module>

dom.setMetadata(conn, type, 'meta_test', key, uri)

File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1460, in setMetadata

ret = libvirtmod.virDomainSetMetadata(self._o, type, metadata, key, uri, flags)

AttributeError: virConnect instance has no attribute '__trunc__'
