[Rdo-list] Openstack Juno Live Migration --block-migrate failed "ValueError: A NetworkModel is required here"

Thu Jan 14 13:20:54 UTC 2016

Hi all,
I'm trying to poupulate the compute dbs on controller node, but I'm getting
this error, I can't figure out why 'cause I'm able to login :

*[root at controller nova]# su -s /bin/sh -c "nova-manage db sync" nova*
*Command failed, please check log for more info*
*[root at controller nova]# more /var/log/nova/nova-manage.log*
*2016-01-14 13:11:15.269 4286 CRITICAL nova [-] OperationalError:

'nova'@'localhost' (using password: YES)")*
*2016-01-14 13:11:15.269 4286 ERROR nova Traceback (most recent call last):*

line 10, in <module>*
*2016-01-14 13:11:15.269 4286 ERROR nova     sys.exit(main())*

but :

*[root at controller nova]# mysql -u nova -p *
*Enter password: r00tme*
*Welcome to the MariaDB monitor.  Commands end with ; or \g.*

connection string in nova.conf file is

*connection=mysql://nova:r00tme@controller/nova*

Any suggestions ?

Cheers
