hi:
Actually, openstack just write some wrappers around libvirt api,
together with some logic related to openstack itself.
for example:
def _lookup_by_name(self, instance_name):
"""Retrieve libvirt domain object given an instance name.
All libvirt error handling should be handled in this method and
relevant nova exceptions should be raised in response.
"""
try:
return self._conn.lookupByName(instance_name)
except libvirt.libvirtError as ex:
error_code = ex.get_error_code()
if error_code == libvirt.VIR_ERR_NO_DOMAIN:
raise exception.InstanceNotFound(instance_id=instance_name)
msg = _("Error from libvirt while looking up %(instance_name)s: "
"[Error Code %(error_code)s] %(ex)s") % locals()
raise exception.NovaException(msg)
self._conn is libvirt connection.
By the way, openstack support multiple virtualization drivers, libvirt
is only one of them.
I think you can treat openstack libvirt api as a reference, then modify
libvirt api to suite your needs.
Thanks.

Thanks all:
And another question : is openstack libvirt-python rewrited by
openstack developers?
here is the openstack libvirt-python doc:
http://wiki.openstack.org/LibvirtAPI
If you install openstack with devstack by default.
You can find the lib in /opt/stack/nova/nova/virt/libvirt
It has these files,but not one file named libvirt.py
"""
root@c65:/opt/stack/nova/nova/virt/libvirt# ls *.py
config.py imagebackend.py snapshots.py volume_nfs.py
driver.py imagecache.py utils.py volume.py
firewall.py __init__.py vif.py
"""
I think I may use it.

hi:
Matbe there's no libvirt python api document. You can lookup the
api directly from the libvirt.py file.
In my machine, libvirt.py is located at
/usr/lib/python2.7/site-packages/libvirt.py.
And, you can lookup the ruby api and c api for a reference, most
of them are the same name.
Thanks.
