libvirt users - Jun 2014 - TCP connection works for only remote host

tcp connection working only for remote host . for localhost raising the
following error
>>> con=libvirt.open("qemu+tcp:///system")
libvirt: XML-RPC error : unable to connect to server at
'localhost:16509':
Connection refused
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/home/fluent/cvt/convirt-enterprise/tg2env/local/lib/python2.7/site-packages/libvirt.py",
line 239, in open
    if ret is None:raise libvirtError('virConnectOpen() failed')
libvirt.libvirtError: unable to connect to server at 'localhost:16509':
Connection refused
>>>
Is there any other params to be set for local host connection..? please help

Restarted libvirt to listen at tcp
$ sudo /etc/init.d/libvirt-bin stop
[sudo] password for fluent:
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service libvirt-bin stop

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) utility, e.g. stop libvirt-bin
libvirt-bin stop/waiting
$ sudo libvirtd -d --listen



Now am getting this error :

libvirt: XML-RPC error : authentication failed: Failed to start SASL
negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

line 239, in open
    if ret is None:raise libvirtError('virConnectOpen() failed')
libvirt.libvirtError: authentication failed: Failed to start SASL

Because you have authentication set up and you're not calling
OpenAuth() you have to change one of those.
