juju nova-controller failed relation with MYSQL

[wahi]

Dear all,

I am trying to build Openstack using two virtual machines (for some 
experiment only). The virtual machines are big with 12GB RAM and several 
cores etc.

I started to deploy each required service one-by-one, let me clarify 
that I will not use CEPH for this stage.

Almost everything is running perfectly, the only error which I am 
getting is this:
hook failed: "shared-db-relation-changed" for mysql:shared-db    for 
nova-controller

The MYSQL and nova-controller are on the same VM, I binded the VM IP to 
mysql and granted the user nova to access the mysql with the 
auto-generated password. I did the same step for glance and keystone and 
it worked without any problem.

Could you please help me to understand what is the problem ? and how can 
I solve it ?

Thank you very much in advance.



Regards,
  Wahi
