SUMMARY

I'm creating this bug report to track CLOUDSTACK-9885, since there's nothing in any milestones over here for it. A PR #2128 was created, but the PR wasn't completed an alternative solution proposed. #2719 attempted to address the general situation, but missed the specifics of needing to delete a tier.

Short version - VPC with Deleted Tier and Private Gateway may have keepalived configured on the private gateway, leading to both VRs in MASTER.

STEPS TO REPRODUCE

1. Create Redundant VPC, configure a Tier 1 (+deploy VM)
2. Add Private Gateway
3. Add Tier 2 (+deploy VM)
4. Delete Tier 1

EXPECTED RESULTS

Keepalived should be configured on the interface for Tier 2

ACTUAL RESULTS

Keepalived was configured on the interface for Private Gateway (first interface with traffic type = Guest)
