After ctrl reboot, no external connectivity from tenant vms

[Navneet Grewal]

Environment:

Mirantis 7.0 - MOS 7 with update 2

Setup:
2x Controllers on VMWare as VMs
2x Compute - Physical Dell PE 1950 Gen III
2x Ceph - Physical Dell C2100

Deploying new environment with following specs:
VXLAN network segmentation
No L2POP

After every successful deployment to all nodes, I can login to horizon as admin and create new tenant.

Login as new tenant and create new network, subnet, router. Launch a VM and ping external IP (Like google.com) successfully.

Now, I decided to reboot my controller nodes, one at a time. After both controllers come back online, I can login to dashboard successfully.

PROBLEM: I console into the VM as a tenant, and can not longer PING outside (like google.com). I decided to start fresh by deleting everything in that tenant space (vms, router, network, subnet). Re-created network, subnet, router, and vm.

Tried to PING google.com - and failure.

I have successfully re-created this problem several times with exact same setup. Problem only occurs after controller nodes are rebooted.

@Navneet, could you please try to reproduce the issue using the freshly downloaded and installed MU-2? We have fixed there several packages recently, and it looks like it should resolve your problem.
