Do You have link to logs of such failed test? I would like to take a look why port was DOWN all time.

[Manik Bindlish (manikbindlish19)]

I think, merging of https://review.openstack.org/#/c/383049 will solve the purpose of this issue.

[Attila Fazekas (afazekas)]

The port implicitly created with the machine should not be down state after the machine become active, the interfaces added later may require time for being wired.

@Sofiia Andriichenko: Are you still working on this issue or should we move it to un-assigned category so that someone can assign it and fix it?
