Hi all I have created one openstack using one controller node and one compute node both installed using devstack.I'm running one instance on controller node and want to migrate it to over compute node. I'm using following link for this.
http://docs.openstack.org/grizzly/openstack-compute/admin/content/live-migration-usage.html http://docs.openstack.org/grizzly/openstack-compute/admin/content/configuring-migrations.html The output of nova-manage vm list on the compute node is as follows.. 10 16:01:49.502 DEBUG nova.openstack.common.lockutils [req-019d2337-143e-4157-9d6c-3c1f2207f63b None None] Semaphore / lock released "__get_backend" inner /opt/stack/nova/nova/openstack/common/lockutils.py:252 Command failed, please check log for more info 2014-03-10 16:01:49.507 CRITICAL nova [req-019d2337-143e-4157-9d6c-3c1f2207f63b None None] Could not parse rfc1738 URL from string '' 2014-03-10 16:01:49.507 9609 TRACE nova Traceback (most recent call last): 2014-03-10 16:01:49.507 9609 TRACE nova File "/usr/bin/nova-manage", line 10, in <module> 2014-03-10 16:01:49.507 9609 TRACE nova sys.exit(main()) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/cmd/manage.py", line 1378, in main 2014-03-10 16:01:49.507 9609 TRACE nova ret = fn(*fn_args, **fn_kwargs) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/cmd/manage.py", line 658, in list 2014-03-10 16:01:49.507 9609 TRACE nova context.get_admin_context(), host) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/db/api.py", line 671, in instance_get_all_by_host 2014-03-10 16:01:49.507 9609 TRACE nova return IMPL.instance_get_all_by_host(context, host, columns_to_join) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/db/sqlalchemy/api.py", line 112, in wrapper 2014-03-10 16:01:49.507 9609 TRACE nova return f(*args, **kwargs) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/db/sqlalchemy/api.py", line 2078, in instance_get_all_by_host 2014-03-10 16:01:49.507 9609 TRACE nova use_slave=use_slave).filter_by(host=host).all(), 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/db/sqlalchemy/api.py", line 2066, in _instance_get_all_query 2014-03-10 16:01:49.507 9609 TRACE nova use_slave=use_slave) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/db/sqlalchemy/api.py", line 200, in model_query 2014-03-10 16:01:49.507 9609 TRACE nova session = kwargs.get('session') or get_session(slave_session=use_slave) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/openstack/common/db/sqlalchemy/session.py", line 423, in get_session 2014-03-10 16:01:49.507 9609 TRACE nova engine = get_engine(sqlite_fk=sqlite_fk, slave_engine=slave_session) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/openstack/common/db/sqlalchemy/session.py", line 561, in get_engine 2014-03-10 16:01:49.507 9609 TRACE nova sqlite_fk=sqlite_fk) 2014-03-10 16:01:49.507 9609 TRACE nova File "/opt/stack/nova/nova/openstack/common/db/sqlalchemy/session.py", line 629, in create_engine 2014-03-10 16:01:49.507 9609 TRACE nova connection_dict = sqlalchemy.engine.url.make_url(sql_connection) 2014-03-10 16:01:49.507 9609 TRACE nova File "/usr/lib/python2.7/site-packages/sqlalchemy/engine/url.py", line 178, in make_url 2014-03-10 16:01:49.507 9609 TRACE nova return _parse_rfc1738_args(name_or_url) 2014-03-10 16:01:49.507 9609 TRACE nova File "/usr/lib/python2.7/site-packages/sqlalchemy/engine/url.py", line 219, in _parse_rfc1738_args 2014-03-10 16:01:49.507 9609 TRACE nova "Could not parse rfc1738 URL from string '%s'" % name) 2014-03-10 16:01:49.507 9609 TRACE nova ArgumentError: Could not parse rfc1738 URL from string '' 2014-03-10 16:01:49.507 9609 TRACE nova Please help me regarding the above error.
