Tap port creation

asked 2018-02-12 08:41:09 -0500

Hi OpenStack Community

During live migration, the destination Compute Node has to perform some 'pre live migration't tasks, among them is the tap creation at the destination OVS.

I would like to know if once Nova creates such tap interface, is the port/tap status UP?.
This is the behavior I am experiencing, but I am not sure whether it is the default one or not?

In case it is, is it possible to delay such action to the 'post live-migrations tasks'. I am thinking of something like this

  • Pre Live-migration : Create port/tap interface at destination Compute Node, but status DOWN
  • Live-migration
  • Post Live-migration : Delete port at source Compute Node, set port/tap interface at destination Compute Node UP

Thanks for your time

Best Regards, Jorge Gomey
