Description of problem:
Create a port. Create a VM attached to this port with customised SG. SG associated with the port should be updated to include the SG specified in VM creation.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create port
2. Create VM attached to this port with custom SG
3. See SGs associated with both VMs and port
Custom SG does not apply to port.
Custom SG should be applied to port.
There is a workaround.
Manually update the security group of the port by running
openstack port update --security-group SG1_ID --security-group SG2_ID PORT_ID
We need to specify this workaround in our docs specially for VLAN aware VM use cases.
