Libvirt-qpid

Installation

libvirt-qpid is currently available in Fedora 10 repositories so you can install it using yum

# yum -y install libvirt-qpid qpidd python-qpid
# chkconfig libvirt-qpid on
# chkconfig qpidd on

We can check that it is running using qpid-tool and the list command

Simple client in python

Now that we have it running lets make a simple client to get information from it. To do this I use python. The following is a simple script that does some of the basics

#!/usr/bin/env python

from qmf.console import Session
from yaml import dump


sess = Session() # defaults to synchronous-only operation. It also defaults to user-management of connections. 

# attempt to connect to a broker
try:
    broker = sess.addBroker('amqp://localhost:5672')
    print "Connection Success"
except:
    print "Connection Failed"


domains = sess.getObjects(_class='domain', _package='com.redhat.libvirt.domain')

# Print a list of the domains
for d in domains:
    print d

# Select the first domain
domain = domains[0]


# Print a list of the properties of the domain
print 'Properties:'
props = domain.getProperties()
for prop in props:
    print "\t",prop

# Access a value of a property and print it 
print domain.name


# Print a list of the methods of the domain
print 'Methods:'
meths = domain.getMethods()
for meth in meths:
    print "\t",meth

# Ca method of the domain and print it 
xmldesc =  domain.getXMLDesc()

# Call another method of the domain and print the result
if domain.state == 'running':
    result = domain.shutdown()
    print result
else:
    result = domain.create()
    print result

# Disconnect from the broker (otherwise we hang the terminal
sess.delBroker(broker)
