My instnance of VIO is connected to NSX.
When im trying to edit/create/delete rules on my security group im getting an error like :
Unable to delete rule: ALLOW IPv4 to 0.0.0.0/0
Error: Unable to add rule to security group.
Need some advice, why I can add new rules to any of security group.
Still issue persist ? what do you see in neutron-server.log?
