[libvirt-users] where is libvirt-python document??

[Hanyu Xiao]

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.
