Deployment of OpenStack Issues Summary (iv)--openstack in Nova-compute state status display as ' XXX ' issue

The first time I deployed OpenStack, I met this problem, and the version was Havana,

Now deploy Essex time again encountered this problem, after some toss, solved this problem, record down, lest forget later.

===========================================================

1. View the/var/log/nova/nova-compute.log file there is a situation where:

Domain not found:no domain with matching name ' instance-00000008 '

2. Backup Document /usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py to Commection.py.bak

3. Editing /usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py

Find this line:virt_dom = self._conn.lookupbyname (instance[' name ')

And then delete this line

Add in the location of the deletion:

# note:in case of no domain up try:virt_dom = self._conn.lookupbyname (instance[' name ') except Exception, E:virt_dom = None

find this line again . XML = Virt_dom. Xmldesc (0) to delete the previous sentence of this line:if not xml:

Add again at the place of deletion:

If Virt_dom:xml = Virt_dom. Xmldesc (0) Else:xml = Self.to_xml (instance, network_info)

Finally find this line:

Self.destroy (instance, Network_info, Cleanup=false) The next behavior in this line (Self.plug_vifs (instance, network_info)) and added in its previous row

If Virt_dom:

Go to catalogue cd/var/lib/nova/instances/instance-00000008

Execute commands in this directory

Virsh Define Libvirt.xml

Then restart the instance. Then restart the Nova-compute service, check the Nova-manage Service list discovery is still xxx, and see in log this situation:

CRITICAL Nova [-] Invalid syntax (connection.py, line 397) #说明在397行的语法有问题.

Then the

/usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py changed the name to CONNECTION.PY.BAK2 (the reason is number 2, Because Connection.py.bak has been created before)

This time will

/usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py.bak Change to connection.py

and give permission: chmod 777 connection.py

Restart Nova-compute Services, service nova-compute restart View Nova-manage Service list service has become a smiley face;
