thank you, glad you sorted it out!

After few minutes trying to figure out what went wrong. I updated openstack on the compute node to the latest software update. Then the problem got fixed. I think I had this problem in the first place because I only updated the controller, so there was an API backward incompatibility with the old and the new update of nova? ( "as validate_console_port" function could not be found otherwise )

Anyway this is for everyone else who is having the same problem.

Best,
Chathura
