sos reports from compute-0

Description of problem:
Nova reports overcloud instance in error state after failed instance-ha evacuation
This does NOT happen while doing the same procedure (see steps to reproduce) with 'evacuable' tagged images (using: openstack server --tag evacuable)

Environment :
OSP12 on virt setup, with instance-ha enabled,no shared storage



How reproducible:
Always

Steps to Reproduce:
1) deploy OSP12 with HA env (3 controllers + 2 computes)
2) deploy instance-ha with non_shared_storage option using the following procedure :
- https://github.com/redhat-openstack/tripleo-quickstart-utils
- https://github.com/redhat-openstack/tripleo-quickstart-utils/tree/master/roles/instance-ha
3) boot 4 instances with fip's (no volumes attached as we are using non_shared_storage instance-ha setup)
4) failover the compute hypervisors (echo b >/proc/sysrq-trigger), each two times, with each failover ,wait for evacuation of the instances.
5) after two failovers instances go into ERROR state.

Expected result : 
after two failovers instances go into AcTIVE state on a different hypevisor.

Attachments: the sos-reports from the computes.
