As expected the port created has no security groups associated with it.

Now, doing a nova boot on this port, results in the VM getting into
error state. is that the expected behavior?

stack@whiskey:~$ nova boot vm --flavor 1 --image cirros-0.3.4-x86_64-uec --nic port-id=33095bd6-3a5c-4ccd-9e4f-046fb7f9272e

I can however boot a vm on a port where port_security_enabled=False
under a network where the port_security_enabled=true as expected.

I was not expecting that an instance cannot be launched under a network
where the value of port_security_enabled is false. Is that the expected
behavior? If yes what's the reason? We don't need security-groups when
port-security-enabled=false, correct? Why should vm boot be blocked then
on such a network?

  As expected the port created has no security groups associated with
  it.

  Now, doing a nova boot on this port, results in the VM getting into
  error state. is that the expected behavior?

  I can however boot a vm on a port where port_security_enabled=False under a network where the port_security_enabled=true as expected.

  I was not expecting that an instance cannot be launched under a
  network where the value of port_security_enabled is false. Is that the
  expected behavior? If yes what's the reason? We don't need security-
  groups when port-security-enabled=false, correct? Why should vm boot
  be blocked then on such a network?
