From 4a7f3398f115a4eaab6993b0aad9c16fa7f55afa Mon Sep 17 00:00:00 2001 From: Oliver Walsh Date: Thu, 8 Jun 2017 00:17:53 +0100 Subject: Add support for nova live/cold-migration with containers Updates hieradata for changes in https://review.openstack.org/471950. Creates a new service - NovaMigrationTarget. On baremetal this just configures live/cold-migration. On docker is includes a container running a second sshd services on an alternative port. Configures /var/lib/nova/.ssh/config and mounts in nova-compute and libvirtd containers.
