Comment 4 for bug 1559758

Hi,

 The issue related to 1559758 is resolved by installing libvirt-python
,lxml,nova and neutron clients.

/opt/monasca-agent/bin/pip install libvirt-python
/opt/monasca-agent/bin/pip install lxml

But still monasca is unable to monitor the newly created vm.

Here is the log:
2016-04-19 00:13:28 MDT | ERROR | collector |
monasca_agent.collector.checks.check.libvirt(libvirt.py:451) |
instance-00000002 is not known to nova after instance cache update --
skipping this ghost VM.
Already bug is raised on the above issue and it is in closed state,but it
is not working in the lates setup.

Subject: [Bug 1559758] Re: libvirt.yaml failed to load
Sent by: <email address hidden>

Hi,

I managed to reproduce the issue in DevStack on current master.

2016-05-03 08:01:04 CEST | ERROR | collector |
monasca_agent.collector.checks.check.libvirt(check.py:248) | Check
'libvirt' instance #0 failed
Traceback (most recent call last):
  File
"/opt/monasca-agent/local/lib/python2.7/site-packages/monasca_agent/collector/checks/check.py",
line 246, in run
    self.check(instance)
  File
"/opt/monasca-agent/lib/python2.7/site-packages/monasca_agent/common/../collector/checks_d/libvirt.py",
line 428, in check
    for inst in insp._get_connection().listAllDomains():
AttributeError: 'Inspector' object has no attribute '_get_connection'

I'd like to look into this and try to find a solution if no one is
working on it right now.
