Openstack Live Migration of instances with iSCSI based boot volumes will not work

Solution Unverified - Updated -

Issue

  • Creating a boot volume from an image and starting the instance using this boot volume works. Live Migration also succeeds, but the access to the boot volume is lost after migration
  • I am not able to successfully live migrate an instance that uses an iSCSI boot disk.
  • The instance loses access to its boot volume on iSCSI after live migration finishes.

Environment

  • Red Hat OpenStack (RHOSP) 7.0
  • overcloud-full image used to deploy overcloud
