We spawned 72 VMs on top of 3 compute nodes, using heat (24 VMs per one node).
Some instances weren't reachable via tenant network. For example:
| 93b95c73-f849-4ffb-9108-63cf262d3a9f | cassandra_vm_0 | ACTIVE | slice0-node162-net=11.62.0.8, 10.144.1.35 | ubuntu-software-config-last |

root@node1:~# ssh -i .ssh/slace ubuntu@10.144.1.35
Connection closed by 10.144.1.35 port 22

it's unreachable from tenant network as well. For example from instance b1946719-b401-447d-8103-cc43b03b1481 which has been spawned by the same heat stack on the same compute node (node162): http://paste.openstack.org/show/593486/

Environment description:
k8s deployed by Kargo on top of 200 hardware nodes.

logs from OpenStack pods and outputs of some commands have been dumped by this script: http://paste.openstack.org/show/593487/
And will be attached soon.
