Open Stack

Yes, we want to use the same naming conventions when possible.
Submitted a fix here: https://review.openstack.org/#/c/315799/

  I'm trying Kuryr with networking-calico and think I've hit an unhelpful

  generates the Linux device name from 'tap' + port['id']. But when Kuryr
  does VIF binding for a Neutron port, I think it generates the Linux
  device name from 'tap' + port['device_id'].

  Thoughts? Does that sound right, or have I misread the code and my logs?
  If it's correct, it marginally impacts the ability to use identical agent
  and Neutron driver/plugin code for the two cases (Nova and Kuryr).

I think we are supposed to behave like Nova, binding wise.

@Banix: Can you confirm that it is a bug and not a feature?

>From a quick grepping I see hat nova sets the name to be:

    nova/network/neutronv2/api.py:                devname = "tap" +
current_neutron_port['id']

Whereas in Kuryr we use the first 8 characters of the Docker endpoint id.


  Thanks,
